The test case design is a crucial aspect of the software testing process, determining the effectiveness and efficiency of our testing efforts. To ensure comprehensive test coverage and the detection of critical defects, we must employ well-thought-out test case design techniques.
This technique divides the input data into equivalent classes, allowing us to select representative test cases from each class. By testing a single representative from each class, we can identify defects that affect the entire class, optimizing our test coverage.
By focusing on the boundaries of equivalent classes, we test scenarios where input values are at the extremes. This technique helps uncover defects that might occur at the edges of acceptable ranges.
In situations with multiple conditions and combinations, decision tables come to the rescue. This technique organizes test cases in a tabular format, simplifying complex logic and ensuring exhaustive testing of all possible scenarios.
Ideal for testing systems with different states, this technique explores how the application transitions from one state to another. It helps identify defects related to state changes and validates the system's behavior in various scenarios.
By selecting a combination of input parameters that have the highest probability of causing defects, this technique minimizes the number of test cases while maintaining thorough coverage.
This technique revolves around testing the application's functionalities based on user interactions, ensuring that the system aligns with real-world usage.
Drawing from the tester's experience, this technique involves predicting potential defects based on past knowledge or intuition. While informal, it can uncover defects that might have been overlooked by other techniques.
Using models of the system, this technique generates test cases automatically, reducing manual effort and increasing efficiency.
