In RSI Phase 5, what is meant by 'test case design'?

Test case design refers to the process of creating specific conditions and scenarios under which a particular functionality of a software application is tested. The goal of this process is to ensure that the software behaves as expected under various circumstances, which can include input values, environment setups, and execution paths.

By defining these conditions clearly, developers and testers can systematically evaluate the functionality of the software and verify that it meets the requirements and quality standards. Good test case design is essential for identifying edge cases, ensuring coverage of all functionalities, and facilitating effective regression testing.

The other options each focus on different aspects of the software development process. Creating user permissions relates to security and access control, designing software architecture deals with the overall structure of the application, and documenting user experience focuses on the usability and interface design rather than testing methodologies. These elements, while important in their own right, do not encapsulate the concept of test case design as effectively as creating specific testing conditions does.
