How to Create a BDD Automation Framework using Cucumber in Java and Playwright? 

How to Create a BDD Automation Framework using Cucumber in Java and Playwright? 

Behavior Driven Development (BDD) is a process that promotes collaboration between developers, testers, and stakeholders by writing test cases in simple, plain language. BDD Automation Frameworks like Cucumber use Gherkin to make test scenarios easily understandable and link them to automated tests.

In this guide, we’ll show you how to create a BDD Automation Framework using Java and Playwright. Playwright is a powerful browser automation tool, and when combined with Java and Cucumber, it creates a solid BDD testing framework.

Introduction to BDD Automation Framework:

BDD Automation Framewrok

Automation testing is testing software with the latest tools and technologies with developed scripts in less time. In Automation testing it involves test case execution, data validation, and result reporting.

Why Playwright over Selenium? 

Playwright is an open-source Node.js library that further enables efficient end-to-end (E2E) testing of web applications. As Playwright offers better performance speed than Selenium. Also, Playwright offers various features like Cross-Brower support, Multi-platform, Headless and Headful Mode, Async/Await API, Integration with Testing Frameworks. 

What is BDD Automation Framework? 

BDD framework is an agile approach to test software where testers write test cases in simple language so that non-tech person can also understand the flow. Moreover, it enhances collaboration between the technical team and the business team. We use Gherkin language to write feature files, making them easily readable by everyone.

4. Cucumber 

https://mvnrepository.com/artifact/io.cucumber/cucumber-java/7.11.0

Prerequisites

  • Java Development Kit (JDK): Ensure you have JDK installed and properly configured. 
  • Maven or Gradle: Depending on your preference, however, you’ll need Maven or Gradle to manage your project dependencies. 

Steps to Install Cucumber with Maven 

  1. Create a Maven Project: 
  2. Update pom.xml File: 
    • Open the pom.xml file in your project. 

This Maven POM file (pom.xml) defines project metadata, dependencies on external libraries (Cucumber, Selenium, Playwright), and Maven build properties. It provides the necessary configuration for managing dependencies, compiling Java source code, and integrating with Cucumber, TestNG, Selenium, and Playwright frameworks to support automated testing and development of the CalculatorBDD project. 

Project Setup or BDD Automation Framework:

Before starting the project on the BDD Automation Framework: 

  • Create a new Maven project in your IDE.
  • Add the dependencies in Pom.xml file .
  • Create folder structure following steps given below: 
Folder Structure

When we created the new project for the executable jar file, we could see the simple folder structure provided by Maven.  

  1. SRC Folder: The SRC folder is the parent folder of a project, and it will also include the main and test foldersIn the QA environment, we generally use the test folder, while we reserve the main folder for the development environment. The development team uses the main folder, so the created JAR contains all the files inside the src folder.
  2. Test Folder: Inside the test folder; additionally, Java and resources folders are available.  
  3. Java Folder: This folder primarily contains the Java classes where the actual code is present. 
  4. Resources Folder: The Resources folder contains the resources file, test data file, and document files. 
  5. Pom.xml: In this file, we are managing the dependencies and plugins that are required for automation.

As our project structure is ready so we can start with the BDD framework: 

1. Feature file: 

Here we have described the scenario in “Gherkin” language which is designed to be easily understandable by non-technical stakeholders as well as executable by automation tools like Cucumber. Each scenario is written in structured manner using keywords “Given”, “When” and “Then”. Calculator.feature in this we have specifically written our functional testing steps. 

2. Step Def File: 

The step definition file serves as the bridge between actual feature file with the actual method implementation in the page file. The Calculator steps are a step definition file that maps the feature file to the page file and functional implementation.

3. Page File:

Page file, in addition, is actual code implementation from the step definition file.Here, we have saved all the actual methods and web page elements, thereby ensuring easy access and organization. It is basically POM structure. So here we are performing addition operation in Calculator we application so created a method to click on a number and another method for clicking on the operator. Here we can minimize the code by reusing the code as much as possible. 

4. Hooks: 

Hooks are setup and teardown methods that, therefore, are written separately in the configuration class. Here we have annotation declare in the hooks file @before and @After. Hooks are steps to be performed a before and after function of the feature file. In this we have open the Web browser in Before and After Tag. These are special functions which allows the testers to execute specific points during execution. 

5. TestContext: 

The TestContext class, moreover, holds various instances and variables required for test execution. In this context, we have successfully created a web driver instance, a page file instance, and a browser context. As a result, the code reusability, organization, and maintainability are improved here.

6. TestRunner: 

The Test Runner is responsible for discovering test cases, executing them, and reporting the results back; additionally, it provides the necessary infrastructure to execute the tests and manage the testing workflow. It also syncs the feature file with step file. 

7. WebUtils:

Web Utils is a file in which browser instance is created and playwright is initialised here. The code for web browser page launching is written here and for closing the browser instance. The page is extended by TestContext where all the properties of TestContext are given to WebUtils page. 

This is the important file where we download all the dependencies required for the test execution. Also, it contains information of project and configuration information for the maven to build the project such as dependencies, build directory, source directory, test source directory, plugin, goals etc. 

This are the dependencies required to download: 

https://mvnrepository.com/artifact/io.cucumber/cucumber-java
https://mvnrepository.com/artifact/io.cucumber/cucumber-testng
https://mvnrepository.com/artifact/com.microsoft.playwright/playwright

Conclusion: 

In this blog, we’ve discussed using the Java Playwright framework with Cucumber for BDD. Playwright offers fast, cross-browser testing and easy parallel execution, making it a great alternative to Selenium. Paired with Cucumber, it helps teams write clear, automated tests. Playwright’s debugging tools and test isolation also reduce test issues and maintenance, making it ideal for building reliable test suites for faster, higher-quality software delivery.

How to Build Right Testing Pyramid?

How to Build Right Testing Pyramid?

“The Right Testing Pyramid is a widely adopted concept in software testing methodologies; therefore, it guides teams in structuring their automated testing efforts efficiently.” 

While planning to build a product, we need to carefully balance the different components of the product whether its software, hardware or a combination of both. 

To create a successful and valuable product, you need to ensure several key aspects.

User Needs and Requirements, Quality, Reliability, User experience, Security, Privacy, Scalability, Compatibility, documentation, compliance etc. 

Quality and reliability are essential pillars for every product; therefore, whether it is software, hardware, or a blend of both, they remain crucial. They are indispensable in ensuring customer satisfaction and, therefore, in the creation of superior products.

The Right Testing Pyramid, therefore, acts as a mediator in achieving high quality and reliability in software development through its structured approach to testing at different levels.

The software development project begins with the use of Testing Pyramid concepts and, moreover, maintains them throughout its lifecycle.

How does the Right Testing Pyramid organize software testing into different layers?

Mike Cohn introduced the right testing pyramid as an analogy for structuring software testing; Consequently, it has become widely adopted in engineering circles and remains the industry standard. The right testing pyramid conceptually organizes testing into three layers.

Testing Pyramid

At the bottom of the pyramid are unit tests. These tests check small parts of the code like functions or classes to make sure they work correctly. Unit tests run the code directly and check the results without needing other parts of the software or the user interface; therefore, they are more isolated and efficient.

Moving up one level from unit tests, we have integration tests (or service tests). These tests check how different parts of the system work together, like making sure a database interacts correctly with a model, or a method retrieves data from an API. They don’t need to use the user interface; instead, they interact directly with the code’s interfaces. 

At the top of the pyramid are end-to-end tests (E2E), also known as UI tests. These tests simulate real user interactions with the application to ensure its functionality. Unlike a human conducting manual testing, E2E tests automate the process entirely. They can click buttons, input data, and verify the UI responses to ensure everything functions correctly. 

As you can observe, the three types of tests vary significantly in their scopes: 

  1. Unit tests are quick and efficient, pinpointing logic errors at the basic code level. They demand minimal resources to execute. 
  2. Integration tests validate the collaboration between services, databases, and your code. They detect issues where different components meet. 
  3. E2E tests require the entire application to function. They are thorough and demand substantial computing power and time to complete. 
Level of Testing pyramid

Why We Should Use Testing Pyramid?

The characteristics of each test type determine the shape of the pyramid.

Unit tests are small-scale and straightforward to create and manage. Due to their focused scope on specific code segments, we typically require numerous unit tests. Fortunately, their lightweight nature allows us to execute thousands of them within a few seconds. 

 Application

End-to-end (E2E) tests are more challenging to create and maintain, use a lot of resources, and take longer to run. They validate a wide range of application functions with just a few tests, so they need fewer tests overall.

Integration of Application

In the middle of the testing pyramid, integration tests are comparable in complexity to unit tests. However, we require fewer integration tests because they focus on testing the interfaces between components in the application. Integration tests demand more resources to execute compared to unit tests but are still manageable in terms of scale. 

Do you understand why the pyramid has its shape? Each layer represents the recommended amount of different types of tests: a few end-to-end tests, some integration tests, and lots of unit tests.

Test Pyramid Level

As you move up the pyramid, tests become more complex and cover more of the code. This means they take more effort to create, run, and maintain. The testing pyramid helps balance this effort by maximizing bug detection with the least amount of work. 

Test Pyramid Effeciency

The Testing Pyramid shape often naturally appears in software development and testing for several reasons: 

1. Progressive Testing Needs: Initially, developers focus on unit tests because they are quick to write and provide immediate feedback on individual code units. As the project progresses and we integrate more components, we naturally need integration tests to ensure these components work together correctly. 

2. Development Lifecycle: At the outset of a project, there’s typically a focus on building core functionalities and prototypes. End-to-end tests, which require a functional application, are challenging to implement early on. Developers prioritize unit and integration tests during this phase to validate foundational code and ensure basic functionality. 

3. Developers can run unit tests frequently during development because they are lightweight and execute quickly. Integration tests require more resources but are still feasible as the project advances. We defer end-to-end tests until later stages when the application matures due to their complexity and dependency on a functional UI.

4. Adoption of Testing Frameworks: Frameworks like Behavior-Driven Development (BDD) encourage writing acceptance tests (including E2E tests) from the project’s outset. When teams adopt such frameworks, they are more likely to incorporate end-to-end testing earlier in the development process. 

In essence, the pyramid shape reflects a natural progression in testing strategies based on the evolution of the software from its initial stages to more mature phases. Developers and testers typically begin with unit tests, add integration tests as they build components, and implement end-to-end tests once the basic functionality stabilizes.

Another factor influencing the pyramid is test speed.

Developers run faster tests more frequently, providing crucial feedback quickly for productive development. 

Tests at the bottom of the pyramid are quick to run, so developers write many of them. Fewer end-to-end tests are used because they are slower. For example, a large web app might have thousands of unit tests, hundreds of integration tests, and only a few dozen end-to-end tests.

Test Speed

Realtime Usage in Industry – 

  1. Unit Tests (Bottom of the Pyramid): 
    • Purpose: Unit tests are the foundation of the pyramid, representing the largest number of tests at the lowest level of the application.
    • Scope: They validate the functionality of individual components or modules in isolation. 
    • Characteristics: Unit tests are typically fast to execute, isolated from external dependencies, and provide quick feedback on code correctness. 
    • Tools: Automated unit testing frameworks such as JUnit, NUnit, and XCTest are commonly used for this layer. 
  1. Service/API Tests (Middle of the Pyramid): 
    • Purpose: Service tests validate interactions between various components or services within the application. 
    • Scope: They ensure that APIs and services behave correctly according to their specifications. 
    • Characteristics: Service tests may involve integration with external dependencies (like databases or third-party services) and focus on broader functionality than unit tests. 
    • Tools: Tools like Postman, RestAssured, and SoapUI are often used for automating service/API tests. 
  1. UI Tests (Top of the Pyramid): 
    • Purpose: UI tests validate the end-to-end behavior of the application through its user interface. 
    • Scope: They simulate user interactions with the application, checking workflows, navigation, and overall user experience. 
    • Characteristics: UI tests are typically slower and more fragile compared to lower-level tests due to their dependence on UI elements and changes in layout. 
    • Tools: Selenium WebDriver, Cypress.io, and TestCafe are examples of tools used for automating UI tests 

Conclusion

The Right Testing Pyramid is a strategic model that emphasizes a balanced and structured approach to testing. It helps teams achieve efficient and effective quality assurance by prioritizing a higher number of unit tests, a moderate number of integration tests, and a focused set of end-to-end tests. This approach not only optimizes testing efforts but also supports rapid development cycles and ensures robust software quality. Some key principles of right test pyramid concluded here : 

  • Automation Coverage: The pyramid emphasizes a higher proportion of tests at the lower levels (unit and service/API tests) compared to UI tests. This optimizes test execution time and maintenance efforts. 
  • Speed and Reliability: Tests at the lower levels are faster to execute and more reliable, providing quicker feedback to developers on code changes. 
  • Isolation of Concerns: Each layer focuses on testing specific aspects of the application, promoting better isolation of concerns and improving test maintainability. 
  • By following the Test Automation Pyramid, teams can achieve a balanced automation strategy that maximizes test coverage, minimizes maintenance overhead, and enhances the overall quality of their software products.

Installation for Modern UI Automation Framework

How to Install Node.js on Windows? 

What is Node.js? 

Node.js is a runtime environment that enables JavaScript to run outside of a web browser; consequently, it allows developers to build scalable and high-performance server-side applications. Originally, JavaScript was confined to client-side scripting in browsers, but with Node.js, it can now power the backend as well. 

For testers, Node.js unlocks powerful automation capabilities but also supports tools and frameworks like WebDriver.io and Puppeteer, which automate browser interactions, manage test suites, and perform assertions. Node.js also facilitates custom test frameworks and seamless integration with testing tools. Additionally, it enables running tests in headless environments, ideal for continuous integration pipelines. Overall, Node.js enhances the effectiveness of JavaScript-based testing, improving software quality, speeding up development and UI Automation. 

Key Features of Node.js

  • Asynchronous and Event-Driven: Node.js library APIs work asynchronously; consequently, they are non-blocking. The server moves to the next API call without waiting for the previous one to complete, therefore it using event mechanisms to handle responses efficiently. 
  • High Speed: Built on Google Chrome’s V8 JavaScript engine, Node.js therefore executes code very quickly. 
  • Single-Threaded but Highly Scalable: Node.js uses a single-threaded model with event looping. This event-driven architecture allows the server to respond without blocking, making it highly scalable compared to traditional servers. Unlike servers like Apache HTTP Server, which create limited threads to handle requests, Node.js can handle thousands of requests using a single-threaded program.

What is Cypress?

Cypress is a modern, open-source test automation framework designed specifically for web applications and used to UI automation also. Unlike many other testing tools that run outside of the browser and execute remote commands, Cypress operates directly within the browser. This unique architecture enables Cypress to offer fast, reliable, and easy-to-write tests, making it an invaluable tool for developers and testers. 

Cypress’s architecture allows it to control the browser in real-time, providing access to every part of the application being tested. This direct control means that tests can interact with the DOM, make assertions, and simulate user interactions with unparalleled accuracy and speed.

Cypress Architecture for Modern UI Automation Framework:

Cypress Architecture for Modern UI Automation Framework

Cypress automation testing operates on a NodeJS server. It uses the WebSocket protocol to create a connection between the browser and the Node.js server. WebSocket’s allow full-duplex communication, enabling Cypress to send commands and receive feedback in real time. This means Cypress can navigate URLs, interact with elements, and make assertions, while also receiving DOM snapshots, console logs, and other test-related information from the browser. 

Let’s break down the components and how they interact: 

  1. User Interaction
    • The process begins with a user interacting with the web application. This includes actions like clicking buttons, selecting values from drop-down menus, filling forms, or navigating through pages. 
  2. Cypress Test Scripts
    • Developers write test scripts using JavaScript or TypeScript. These scripts simulate user interactions and verify that the application behaves as expected. 
  3. Cypress Runner
    • The Cypress Runner executes the test scripts. It interacts with the web application, capturing screenshots and videos during the tests. 
  4. Proxy Server
    • A proxy server sits between the Cypress Runner and the web application. It intercepts requests and responses, allowing developers to manipulate them. 
  5. Node.js
    • Cypress runs on Node.js, providing a runtime environment for executing JavaScript or TypeScript code. 
  6. WebSocket
    • The WebSocket protocol enables real-time communication between the Cypress Runner and the web application. 
  7. HTTP Requests/Responses
    • HTTP requests (e.g., GET, POST) and responses are exchanged between the Cypress Runner and the application server, facilitating the testing process. 

By understanding these components and their interactions, you can better appreciate how Cypress effectively automates testing for modern web applications and UI Automation. 

Features of the Cypress

  • Time Travel: Cypress captures snapshots of your application as it runs, allowing you to hover over each command in the test runner to see what happened at every step. 
  • Real-Time Reloads: Cypress automatically reloads tests in real-time as you make changes, providing instant feedback on your changes without restarting your test suite. 
  • Debuggability: Cypress provides detailed error messages and stack traces, making it easier to debug failed tests. It also allows you to use browser developer tools for debugging purposes. 
  • Automatic Waiting: Cypress automatically waits for commands and assertions before moving on, eliminating the need for explicit waits or sleeps in your test code. 
  • Spies, Stubs, and Clocks: Cypress provides built-in support for spies, stubs, and clocks to verify and control the behavior of functions, timers, and other application features. 
  • Network Traffic Control: Cypress allows you to control and stub network traffic, making it easier to test how your application behaves under various network conditions. 
  • Consistent Results: Cypress runs in the same run-loop as your application, ensuring that tests produce consistent results without flaky behavior. 
  • Cross-Browser Testing: Cypress supports testing across multiple browsers, including Chrome, Firefox, and Edge, ensuring your application works consistently across different environments. 
  • CI/CD Integration: Cypress integrates seamlessly with continuous integration and continuous deployment (CI/CD) pipelines, enabling automated testing as part of your development workflow.

Advantages of Cypress

  • Easy Setup and Configuration: Cypress offers a simple setup process with minimal configuration, allowing you to start writing tests quickly without dealing with complex setup procedures. 
  • Developer-Friendly: Cypress is designed with developers in mind, providing an intuitive API and detailed documentation that makes it easy to write and maintain tests. 
  • Fast Test Execution: Cypress runs directly in the browser, resulting in faster test execution compared to traditional testing frameworks that operate outside the browser. 
  • Reliable and Flake-Free: Cypress eliminates common sources of flakiness in tests by running in the same run-loop as your application, ensuring consistent and reliable test results. 
  • Comprehensive Testing: Cypress supports a wide range of testing types, including end-to-end (E2E), integration, and unit tests, providing a comprehensive solution for testing web applications. 
  • Rich Ecosystem: Cypress has a rich ecosystem of plugins and extensions that enhance its functionality and allow you to customize your testing setup to suit your specific needs. 
  • Active Community and Support: Cypress has an active and growing community that provides support, shares best practices, and contributes to the development of the framework. 
  • Seamless CI/CD Integration: Cypress integrates seamlessly with CI/CD pipelines, enabling automated testing as part of your development workflow. This integration ensures that tests are run consistently and reliably in different environments, improving the overall quality of your software. 

Cypress’s unique features, reliability, and ease of use make it an ideal choice for developers and testers looking to ensure the quality and performance of their web applications.  

By leveraging Cypress in your JavaScript projects, you can achieve efficient and effective UI automation, enhancing the overall development lifecycle. 

Cypress Framework Structure 

In a Cypress project, the folder structure is well-defined to help you organize your test code, configuration, plugins, and related files. Here’s a breakdown of the typical folders and files we will encounter:

1. cypress/ Directory 

  • Purpose: This is the root directory where all Cypress-related files and folders reside.

    • cypress.config.js: Where you configure Cypress. 
  • Optional Directories
    • fixtures/: For test data. 
    • plugins/: For extending Cypress functionality. 
    • support/: For custom commands and utilities. 

This structure helps you customize your testing environment and keep everything well-organized. 

Now let’s start to install Cypress and Configure in our project.

Cypress Install and Configuration:

We’re now ready to dive into the Cypress installation and configuration process. With Node.js, VS Code, and a new project named “CypressJavaScriptFramework” set up, let’s walk through configuring Cypress step-by-step. 

  1. Open Your Project: Start by opening the “CypressJavaScriptFramework” project in VS Code. 
  2. Open a New Terminal: From the top-left corner of VS Code, open a new terminal. 
  3. Initialize Node.js Project: Verify your directory path and run the below command to initialize a new Node.js project and generate a package.json file. 
    • npm init –y 
  4. Install Cypress: Install Cypress as a development dependency with the below command. Once installed, you’ll find Cypress listed in your package.json file. As of this writing, the latest version is 13.13.1. 
    • npm install –save-dev cypress  
  5. Configure Cypress: To open the Cypress Test Runner, run the below command. 
    • npx cypress open

Upon first launch, you’ll be greeted by Launchpad, which helps with initial setup and configuration. 

Step 1: Choosing a Testing Type

The first decision we will make in the Launchpad is selecting the type of testing you want to perform: 

  • E2E (End-to-End) Testing: This option runs your entire application and visits pages to test them comprehensively. 
  • Component Testing: This option allows you to mount and test individual components of your app in isolation. 

Here we must select E2E Testing. 

What is E2E Testing? 

End-to-End (E2E) testing is a method of testing that validates the functionality and performance of an application by simulating real user scenarios from start to end. This approach ensures that all components of the application, including the frontend and backend, work together seamlessly. 

After selecting E2E Testing Configuration Screen where we just have to click on Continue button.

Step 2: Quick Configuration 

Next, the Launchpad will automatically generate a set of configuration files tailored to your chosen testing type. You’ll see a list of these changes, which you can review before continuing. For detailed information about the generated configuration, you can check out the Cypress configuration reference page. 

After clicking on Continue button we will notice some changes in the framework few Configuration files will be added in the Framework which are 
cypress.config.js 
cypress/ directory 
cypress directory Fixtures and Support directory 

The description of these file s and folders we have seen in start of blog.

Step 3: Launching a Browser 

Finally, the Launchpad will display a list of compatible browsers detected on your system. You can select any browser to start your testing. Don’t worry if you want to switch browsers later; Cypress allows you to change browsers at any point of time.  

As in my system I have Chrome and Edge browser installed. Cypress also have the inbuild browser which is called as “Electron” 

What is Electron Browser? 

Electron is an open-source framework that allows developers to build cross-platform desktop applications using web technologies like HTML, CSS, and JavaScript. It combines the Chromium rendering engine and the Node.js runtime, enabling you to create desktop apps that function seamlessly across Windows, macOS, and Linux.

Key Points: 

  • Cross-Platform Compatibility: Develop applications that work on Windows, macOS, and Linux. 
  • Chromium-Based: Uses Chromium, the same rendering engine behind Google Chrome, for a consistent browsing experience. 
  • Node.js Integration: Allows access to native OS functionalities via Node.js, blending web technologies with desktop capabilities. 
  • Used by Popular Apps: Many well-known applications like Slack, Visual Studio Code, and GitHub Desktop are built using Electron. 

Electron provides the flexibility to build powerful desktop applications with the familiarity and ease of web development. 

Now, you’re ready to hit the start button and embark on your testing journey with Cypress! 

In this article we will use chrome browser for that we have to select Chrome and click on “Start E2E Testing in Chrome”. Then we will land on Cypress runner screen here we have 2 options   

  • Scaffold example specs: Automatically generate example test specifications to help you get started with Cypress. 
  • Create new specs: Manually create new test specifications to tailor your testing needs and scenarios. 

Here we will use Scaffold example specs.  

Scaffolding Example Specs 

Use: Scaffolding example specs in Cypress generates predefined test files that demonstrate how to write and structure tests. 

Reason: Providing example specs helps new users quickly understand Cypress’s syntax and best practices, making it easier to start writing their own tests and ensuring they follow a proper testing framework. 

Once we select Scaffold example specs option, we will notice in framework few files are added in cypress directory under e2e directory. 

Finally, we have installed cypress, configured and now we can run Scaffolding Example Specs. Now we will add our own file and execute it with cypress runner and from Command Line. Before that we will go through the Cypress Testing components. 

Cypress Testing Components 

Let’s understand Cypress Testing Components used while automation. 

  • describe() Block: Groups related tests and provides structure. 
  • it() Blocks: Defines individual test cases, focusing on specific functionalities. 
  • Hooks: Manage setup and teardown processes to maintain a consistent test environment. 
  • Assertions: Verify that the application behaves as expected by comparing actual results to expected results. 

describe() Block 

The describe() block in Cypress is used to group related test cases together. It defines a test suite, making it easier to organize and manage your tests. 

Purpose: 

The describe() block provides a structure for your test cases, allowing you to group tests that are related to a particular feature or functionality. It helps in maintaining a clean and organized test suite, especially as your test cases grow in number. 

Example: 

it() Blocks 

The it() block defines individual test cases within a describe() block. It contains the actual code for testing a specific aspect of the feature under test. 

Purpose: 

Each it() block should test a single functionality or scenario, making your test cases clear and focused. This helps in identifying issues quickly and understanding what each test is verifying. 

Example:

Hooks 

Hooks are special functions in Cypress that run before or after tests. They are used to set up or clean up the state and perform common tasks needed for your tests. 

Types of Hooks: 

  • before(): Executes once before all tests in a describe() block. 
  • beforeEach(): Runs before each it() block within a describe() block. 
  • after(): Executes once after all tests in a describe() block. 
  • afterEach(): Runs after each it() block within a describe() block. 

Purpose: 

Hooks are useful for setting up test environments, preparing data, and cleaning up after tests, ensuring a consistent and reliable test environment. 

Example: 

Assertions 

Assertions are statements that check if a condition is true during the test execution. They verify that the application behaves as expected and helps identify issues when the actual results differ from the expected results. 

Purpose: 

Assertions validate the outcomes of your test cases by comparing actual results against expected results. They help ensure that your application functions correctly and meets the defined requirements. 

Example: 

These components work together to create a comprehensive and organized test suite in Cypress, ensuring your application is thoroughly tested and reliable. 

Create Test File 

Before diving into test file creation, let’s define the functionalities. We will automate the Calculator.net web application and will focus on basic arithmetic operations: addition, subtraction, multiplication, and division. 

Here’s a breakdown of the test scenarios:

1. Verify user able to do addition 

  • Visit Calculator.net 
  • Click on two numbers (e.g., 1 and 2) 
  • Click the “+” operator 
  • Click on another number (e.g., 1) 
  • Click the “=” operator 
  • Verify the result is equal to 3 
  • Click the “reset” button 

2. Verify user able to do Subtraction 

  • Visit Calculator.net 
  • Click on a number (e.g., 3) 
  • Click the “-” operator 
  • Click on another number (e.g., 1) 
  • Click the “=” operator 
  • Verify the result is equal to 2 
  • Click the “reset” button 

3. Verify user able to do Multiplication 

  • Visit Calculator.net 
  • Click on a number (e.g., 2) 
  • Click the “*” operator 
  • Click on another number (e.g., 5) 
  • Click the “=” operator 
  • Verify the result is equal to 10 
  • Click the “reset” button 

4. Verify user able to do Division 

  • Visit Calculator.net 
  • Click on a number (e.g., 8) 
  • Click the “/” operator 
  • Click on another number (e.g., 2) 
  • Click the “=” operator 
  • Verify the result is equal to 4 
  • Click the “reset” button

Optimizing with Hooks: 

As you noticed, visiting Calculator.net and resetting the calculator are common steps across all scenarios. To avoid code repetition, we’ll utilize Cypress hooks: 

  • beforeEach: Execute this code before each test case. We’ll use it to visit Calculator.net. 
  • afterEach: Execute this code after each test case. We’ll use it to reset the calculator. 

Now, let’s create the test file and add the code below to Calculator.cy.js file.  

Let’s create a Selectors.json file to store all the selectors used in automation, assigning them meaningful names for better organization. 

The Selector.json file is a crucial part of your test automation framework. It centralizes all the CSS selectors used in your tests, making the code more maintainable and readable. By keeping selectors in a dedicated file, you can easily update or change any element locator without modifying multiple test scripts. 

Purpose: 

  • Centralization: All element selectors are stored in one place. 
  • Maintainability: Easy to update selectors if the application’s HTML changes. 
  • Readability: Makes test scripts cleaner and easier to understand by abstracting the actual CSS selectors. 

Add the following JSON content to your Selector.json file in the cypress/fixtures directory: 

  • Number Buttons: Selectors for the number buttons (0-9) use the span[onclick=’r(number)’] pattern, identifying the buttons by their onclick attribute values specific to each number. 
  • Operator Buttons: Selectors for the arithmetic operators (plus, minus, multiply, divide) use a similar pattern but include escaped quotes for the operator characters. 
  • Equals Button: The selector for the equals button follows the same pattern, identifying it by its onclick attribute. 
  • Result: The selector for the result display uses an ID (#sciOutPut), directly identifying the output element. 
  • Cancel Button: The selector for the cancel button is included to reset the calculator between tests, ensuring a clean state for each test case. 

By utilizing this Selector.json file, your test scripts can reference these selectors with meaningful names, thereby enhancing the clarity and maintainability of your test automation framework for UI.

Advanced Configuration In cypress.config.js: 

While installing and Configration of cypress we have created cypress.config.js file. Now we will look at the Advanced configuration in cypress.config.js allows you to tailor Cypress’s behavior to fit the specific needs of your project, optimizing and enhancing the testing process. 

Key Benefits: 

  • Customization: You can set up custom configurations to suit your testing environment, such as base URL, default timeouts, viewport size, and more. 
  • Environment Variables: Manage different environment settings, making it easy to switch between development, staging, and production environments. 
  • Plugin Integration: Configure plugins for extended functionality, such as code coverage, visual testing, or integrating with other tools and services. 
  • Reporter Configuration: Customize the output format of your test results, making it easier to integrate with CI/CD pipelines and other reporting tools. 
  • Browser Configuration: Define which browsers to use for testing, including headless mode, to speed up the execution of tests. 
  • Test Execution Control: Set up retries for flaky tests, control the order of test execution, and manage parallel test runs for better resource utilization. 
  • Security: Configure authentication tokens, manage sensitive data securely, and control network requests and responses to mimic real-world scenarios. 

Add below code to cypress.config.js file.

This Cypress configuration file (cypress.config.js) sets various options to customize the behavior of Cypress tests. Here’s a breakdown of the configuration for modern UI Automation: 

  • const { defineConfig } = require(“cypress”);: Import defineConfig function from Cypress, which is used to define configuration settings. 
  • module.exports = defineConfig({ … });: Exports the configuration object, which Cypress uses to configure the test environment. 
    • projectId: “CYFW01”: Specifies a unique project ID for identifying the test project. This is useful for organizing and managing tests in CI/CD pipeline. 
    • downloadsFolder: “cypress/downloads”: Sets the folder where files downloaded during tests will be saved. 
    • screenshotsFolder: “cypress/screenshots”: Defines the folder where screenshots taken during tests will be stored, particularly for failed tests. 
    • video: true: Enables video recording of test runs, which can be useful for reviewing test execution and debugging. 
    • screenshotOnRunFailure: true: Configures Cypress to take screenshots automatically when test fails. 
    • chromeWebSecurity: false: Disables web security in Chrome, which can be useful for testing applications that involve cross-origin requests. 
    • trashAssetsBeforeRuns: true: Ensures that previous test artifacts (like screenshots and videos) are deleted before running new tests, keeping the test environment clean. 
    • viewportWidth: 1920 and viewportHeight: 1080: To simulate a screen resolution of 1920×1080 pixels, you can set the default viewport size for tests accordingly.
    • execTimeout: 10000: Configures the maximum time (in milliseconds) Cypress will wait for commands to execute before timing out. 
    • pageLoadTimeout: 18000: Sets the maximum time (in milliseconds) Cypress will wait for a page to load before timing out. 
    • defaultCommandTimeout: 10000: Defines the default time (in milliseconds) Cypress will wait for commands to complete before timing out. 
    • retries: { runMode: 1, openMode: 0 }
      • runMode: 1: Specifies that Cypress should retry failed tests once when running in CI/CD mode (runMode). 
      • openMode: 0: Indicates that Cypress should not retry failed tests when running interactively (openMode). 
    • e2e: { setupNodeEvents(on, config) { … } }: Provide way to set-up Node.js event listeners for end-to-end tests. This is where you can implement custom logic or plugins to extend Cypress’s functionality. 

Executing Test Cases Locally for Modern UI Automation

To run test cases for modern UI Automation, use Cypress commands in your terminal. Cypress supports both headed mode (with a visible browser window) and headless mode (where tests run in the background without displaying a browser window). 

Running Test Cases in Headed Mode: 

  • Open your terminal. 
  • Navigate to the directory containing your Cypress tests. 
  • Execute the tests in headed mode using the below command: 
    • npx cypress open 

This will open the Cypress Test Runner. Click on “E2E Testing,” select the browser, and run the test case from the list (e.g., calculator.cy.js). Once selected, the test case will execute, and you can see the results in real-time. Screenshots of the local test execution are provided below. 

Running Test Cases in Headless Mode: 

Headless mode in Cypress refers to running test cases without a visible user interface. This method allows tests to be executed entirely in the background. Here’s how you can set up and run Cypress in headless mode. 

To run the test script directly from the command line, use the following command: 

npx cypress run –spec “cypress\e2e\Calculator.cy.js” –browser edge 

By default, Cypress executes tests in headless mode, but you can also specify it explicitly using the –headless flag: 

npx cypress run — headless –spec “cypress\e2e\Calculator.cy.js” –browser edge 

This enables efficient and automated test execution without launching the browser UI (UI Automation).

AI-Assisted Test Case Generation for Web & API: Practical Code Implementation

AI-Assisted Test Case Generation for Web & API: Practical Code Implementation

This blog explores how we can use AI capabilities to automate our test case generation tasks for web applications and APIs, focusing on AI-assisted Test Case Generation for Web & API. Before diving into this topic, let’s first understand why automating test case generation is important. But before that, let’s clarify what a test case is: a test case is a set of steps or conditions used by a tester or developer to verify and validate whether a software application meets customer and business requirements. Now that we understand what a test case is, let’s explore why we create them.

What is the need for test case creation?

  • To ensure quality: Test cases help identify defects and ensure the software meets requirements. 
  • To improve efficiency: Well-structured test cases streamline the testing process. 
  • To facilitate regression testing: You can reuse test cases to verify that new changes haven’t introduced defects.
  • To improve communication: Test cases serve as a common language between developers and testers. 
  • To measure test coverage: Test cases help assess the extent to which the software has been tested.

When it comes to manual test case creation some limitations, disadvantages, or challenges impact the efficiency and effectiveness of the testing process such as: 

What are the limitations of manual test case generation? 

  • Time-Consuming: Manual test case writing is a time-consuming process as each test case requires detailed planning and documentation to ensure the coverage of requirements and expected output. 
  • Resource Intensive: Creating manual test cases requires significant resources and skilled personnel. Testers must thoroughly understand the application and its related requirements to write effective test cases. This process demands a substantial allocation of human resources, which could be better utilized in other critical areas.
  • Human Error: Any task that needs human interactions is prone to error because that is a human tendency and manual test case creation is no exception. Mistakes can occur in documenting the steps, and expected results, or even in understanding the requirements. Which could result in inaccurate test cases that lead to undetected bugs and defects. 
  • Expertise Dependency: Creating high-quality test cases that cover all the requirements and results into high test coverage requires a certain level of expertise and domain knowledge. This creates a limitation especially if those individuals are unavailable or if there is a high turnover rate. 

These are just some of the challenges that I have mentioned but there could be more. Comment down your thoughts on this one. If you have any other challenges then you can share them in the comment section. Now that we have understood why we create a test case and what value it adds in testing along with the limitations for manual test case generation let’s see what are the benefits of automating this test case generation process.

Benefits of automated test case generation:

  • Efficiency and Speed: Automated test case generation significantly improves the efficiency and speed of test case writing. As tools and algorithms drive the process instead of manual efforts, it creates test cases faster and quickly updates them whenever there are changes in the application, ensuring that testing keeps pace with development.
  • Increased Test Coverage: Automated test case generation eliminates or reduces the chances of compromising the test coverage. This process generates a wide range of test cases, including those that manual testing might overlook. By covering various scenarios, such as edge cases, it ensures thorough testing.
  • Accuracy and Consistency: Automating test case generation ensures accurate and consistent creation of test cases every time. This consistency is crucial for maintaining the integrity of the testing process and applying the same standards across all test cases.
  • Improved Collaboration: By standardizing the test case generation process, automated test case generation promotes improved collaboration among cross-functional teams. It ensures that all team members, including developers, testers, and business analysts, are on the same page. 

Again, these are just a few advantages that I have listed down. You can share more in the comment section and let me know what the limitations of automated test case generation are as well.

Before we move ahead it is essential to understand what is AI and how it works. This understanding of AI will help us to design and build our algorithms and tools to get the desired output.

What is AI?

AI test case generation

AI (Artificial Intelligence) simulates human intelligence in machines, programming them to think, learn, and make decisions. AI systems mimic cognitive functions such as learning, reasoning, problem-solving, perception, and language understanding.

How does AI work?

AI applications work based on a combination of algorithms, computational models, and large datasets. We divide this process into several steps as follows.

1. Data Collection and Preparation:

  • Data Collection: AI system requires vast amounts of data to learn from. You can collect this data from various sources such as sensors, databases, and user interactions.
  • Data Preparation: We clean, organize, and format the collected data to make it suitable for training AI models. This step often involves removing errors, handling missing values, and normalizing the data.

2. Algorithm Selection:

  • Machine Learning (ML): Algorithms learn from data and improve over time without explicit programming. Examples include decision trees, support vector machines, and neural networks.
  • Deep Learning: A subset of machine learning that uses neural networks with many layers (deep neural networks) to analyze complex patterns in data. It is particularly effective for tasks such as image and speech recognition. 

3. Model Training:

  • Training: During training, the AI model learns to make predictions or decisions by analyzing the training data. The model adjusts its parameters to minimize errors and improve accuracy. 
  • Validation: We test the model on a separate validation dataset to evaluate its performance and fine-tune its parameters.

4. Model Deployment:

Once the team trains and validates the AI model, they deploy it to perform its intended tasks in a real-world environment. This could involve making predictions, classifying data, or automating processes.

5. Inference and Decision-Making:

Inference is the process of using the trained AI model to make decisions or predictions based on new, unseen data. The AI system applies the learned patterns and knowledge to provide outputs or take actions.

6. Feedback and Iteration:

AI systems continuously improve through feedback loops. By analyzing the outcomes of their decisions and learning from new data, AI models can refine their performance over time. This iterative process helps in adapting to changing environments and evolving requirements.

Note: We are using Open AI to automate the test case generation process. For this, you need to create an API key for your Open AI account. Check this Open AI API page for more details.

Automated Test Case Generation for Web:

Prerequisite:

  • Open AI account and API key
  • Node.js installed on the system

Approach:

For web test case generation using AI the approach I have followed is to scan the DOM structure of the web page analyze the tag and attribute present and then use this as input data to generate the test case. 

Step 1: Web Scrapping

Web scrapping will provide us the DOM structure information of the web page. We will store this and then pass this to the next process which is analyzing this stored DOM structure.

Code Explanation:

  • Install Puppeteer npm package using npm i puppeteer We are using Puppeteer to launch the browser and visit the web page. 
  • Next, we have an async function scrapeWebPage This function requires the web URL. Once you pass the web URL then it stores the tags and attributes from the DOM content. 
  • This function will return the structure and at last will return the web elements. 

Step 2: Analyze elements

In this step, we are analyzing the elements that we got from our first step and based on that we will define what action to take on those elements.

Code Explanation:

  • Here the function analyzePageStructure takes pageStrucure as a parameter, which is nothing but the elements that we got using web scraping. 
  • We are declaring the action array here to store all the actions that we will define to perform. 
  • In this particular code, I am only considering two types i.e. text and submit and tagNames i.e. input and button. 
  • For type text and tag name input, I am adding an action to enter the data. 
  • For type submit and tag name submit I am adding an action to click. 
  • At last, this function will return the actions array. 

Step 3: Generate Test Cases

This is the last step of this approach. Till here we have our actions and the elements as well. Now, we are ready to generate the test cases for the entered web page. 

Code Explanation: 

  • The function generateBddTestCases takes two parameters actions and apikey (Open AI API key) 
  • We have added a prompt along with the actions and API key to generate the test cases. 
  • The API used in the above code is provided by Open AI.

  Then an error message “Invalid username format” should be displayed
   And no script should be executed

Automated Test Case Generation for API:

Approach:

To effectively achieve AI Test Case Generation for APIs, we start by passing the endpoint and the URI. Subsequently, we attach files containing the payload and the expected response. With these parameters in place, we can then leverage AI, specifically OpenAI, to generate the necessary test cases for the API.

Step 1: Storing the payload and expected response json files in the resources folder

  • We are going to use the POST API for this and for POST APIs we need payload.
  • The payload is passed through json file stored in the resources folder. 
  • We also need to pass the expected response of this POST API so that we can create effective test cases. 
  • The expected response json file will help us to create multiple test case to ensure maximum test coverage.

Step 2: Generate Test Cases

In this step, we will use the stored payload, and expected response json files along with the API endpoint.

Code Explanation:

  • Firstly we are reading the two json files from the resources folder i.e. payload.json and expected_result.json
  • Next, use your API key, specify the API URL and endpoint along with callType
  • Write a prompt for generating the test cases. 
  • Use the same Open AI API to generate the test cases.

ADB (Android Debug Bridge) is an invaluable tool for developers, testers and Android enthusiasts alike. It allows you to interact with your Android device from a computer, opening new possibilities for application development and usability improvement. Explore ADB commands for android device manipulation in this blog.  

Android enthusiasts, developers and testers find ADB to be of great utility. It provides several features essential for managing devices and developing apps. 

ADB uses a command-line interface (CLI) to function. This implies that instead of interacting with it through a graphical user interface (GUI), you do it by typing instructions into a terminal or command prompt. 

ADB establishes a connection between your Android smartphone and PC. You can use your computer to control your gadget using this connection and use ADB Commands for Android Device interaction. 

Below are few of the benefits of using the ADB commands for Android Device Control

  • The tool makes it possible to do a variety of interactions with your Android device, which can be useful for both everyday use, development and testing. 
  • By enabling fast access to a device from a development environment, ADB helps developers to build and testers to test applications more efficiently. 
  • By providing access to more complex system capabilities, ADB can assist users in personalizing their devices or troubleshooting problems. 
  • ADB allows you to install apps straight from your development environment onto the device, saving you the trouble of manually moving them there. With the ability to perform diagnostic commands and retrieve error logs, it also aids in troubleshooting applications. 
  • System logs (logcat), which are essential for debugging apps and comprehending system events, can be retrieved by ADB. 
  • When you need to remotely manage a device or perform automated testing, it can mimic human activities like key presses and touch events. 

We’ll go over the most crucial ADB commands in this tutorial, along with their advantages and uses and explore ADB command for Android Device.

But before you start using the ADB commands to manipulate the Android device, you’ll first need to set up your device and computer to enable communication. 
 
Please refer to the Step 7 of the blog by Ajay Salunkhe on How to configure Windows Desktop for Android App Automation using Appium? 

Explore Following ADB Commands to manipulate Android Device

ADB Commands as below

Device Connectivity

Getting comprehensive details on your connected device is one of the most basic things you can do with ADB. For developers and testers who must comprehend the context in which their apps are operating, this is essential which can be achieved by executing the subsequent ADB command: 

This command displays a list of every device that is either networked or USB-connected to your computer. It provides a list of device serial numbers and their status, which can be  

1. “unauthorized” (meaning the device is connected but not authorized for ADB communication),  

2. “offline” (meaning the device is connected but not ready for commands), or  

3. “device” (meaning the device is connected and ready for commands). Making sure your device is correctly connected and prepared to communicate with ADB starts with doing this. 

Device Information

It is critical to understand the characteristics of your Android device. The following is a straightforward shell command that provides detailed information about the currently connected device. 

This command provides a list of exclusive device properties, including the phone number in store memory, the handle number for GSM radio standard communications, the operating system version, the device model, hardware details, and even kernel panics, if necessary. You can think of it as an inside perspective, opening a revealing window that can help identify problems and combine them with public report papers on security bugs to quickly ensure compatibility. 

Battery Power

Battery management is a crucial part of the app development and testing process. You can simulate different battery conditions and examine how your program behaves in response by setting the battery level using adb shell dumpsys. 

This command sets the battery level to 100%, but you can alter it to any percentage you wish. This is quite handy for evaluating your app’s response to low battery conditions, power saving settings, and charging state.

Bluetooth Enable

Many applications rely on Bluetooth capability, particularly those involving IoT devices, wearables, and music streaming. Use the following command to see if Bluetooth is enabled: 

A ‘1’ in the terminal response indicates Bluetooth is enabled, whereas a ‘0’ indicates Bluetooth is turned off. 

To turn on Bluetooth, use 

To turn off Bluetooth: 

Using these commands involves significantly less hardware labor when testing the Bluetooth functionality of your own software.

WiFi Control

Many apps require a Wi-Fi connection. To control the Wi-Fi status on your device, enter the following information: 

– Enable Wi-Fi: 

– Disable Wi-Fi: 

This is particularly handy when evaluating how your app functions without internet connectivity and providing different network situation simulations. 

Airplane Mode

When in airplane mode, all wireless connections are cut off, including Bluetooth, cellular, and Wi-Fi. You can use this to test the offline functionality of your app. Use these commands to switch between Airplane mode ON and Off: 

To enable Airplane mode: 

To disable Airplane mode: 

These commands help you test your app’s behavior in various connectivity scenarios.

Installing an App

Deploying your app to a physical device is a crucial step in development. To install an APK file on your device, use: 

Replace the ‘path-to-apk-file’ with the location of your APK file. This command simplifies the installation process across multiple devices, ensuring consistency.

Putting an App in the Background

Testing how your app behaves when sent to the background and brought back to the foreground is essential for a smooth user experience. To put an app in the background, use: 

The first command simulates pressing the home button, sending the app to the background. The second command brings up the recent apps screen, allowing you to simulate app switching.

Relaunching an App

To relaunch an app, use the `monkey` tool, which sends random events to the system. This is useful for stress testing and ensuring your app can handle unexpected inputs: 

Replace ` app-package ` with your app’s package name. This command launches the specified app, helping you automate the process of starting your app from a clean state.

Uninstalling an App

To uninstall an app from your device, use: 

Replace ` app-package` with the package name of the app you want to uninstall. This command is useful for cleaning up after tests and ensuring no residual data remains on the device.

Making a Call

For apps that interact with the phone’s calling capabilities, being able to initiate calls programmatically is important. To initiate a call from your device, use: 

Replace `1231231234` with the phone number you want to call. This command is useful for testing call-related features and interactions.

Rebooting the Device

Sometimes, a fresh start is needed. To reboot your device, simply use: 

This command restarts your device, ensuring it is in a clean state before starting tests or after making significant changes. 

Conclusion

These ADB instructions are but a sample of what may be accomplished using ADB by developers and testers. They undoubtedly offer a great deal of assistance with your work, including a better way to manage and debug native applications on your device and steps toward automation. These commands can be used in conjunction with your development and testing workflow to improve efficiency and ensure that, for example, an app’s behavior at various signal strengths is tested instantly. This eliminates the need for hours-long testing, which is particularly useful when a developer wants to upgrade or downgrade firmware based on how it will affect performance over varying time periods. This tool couldn’t be more powerful!  

Whether you’re a seasoned developer, tester or just starting out, ADB is the only tool you need with its many helpful commands that can handle anything from making the screen as bright or obscure as you like to completely changing the way Android can be used.  

Gaining control of these ADB commands will benefit you in a variety of testing and development situations, allowing your app to provide a seamless and enjoyable user experience. Thus, give them a go!
