Description: Test case design is the process of creating test cases based on requirements and specifications. This process is fundamental in the realm of software testing and automated testing, as it allows for the verification that the software meets the established expectations and requirements. A well-designed test case includes a clear description of the test’s objective, the steps to follow, the necessary input data, and the expected results. The quality of test cases directly influences the effectiveness of the testing process, as a poorly designed test case can lead to the omission of critical errors. Furthermore, test case design should be systematic and repeatable, facilitating automation. In the context of automated testing, test cases become scripts that can be executed by software tools, saving time and resources in the software validation process. The creation of these test cases is based not only on the software’s functionality but also on user experience, security, and performance, thus ensuring comprehensive test coverage.
