What is the purpose of test cases?

The purpose of test cases is to systematically and thoroughly verify the functionality, performance, and reliability of a software application. Test cases are designed to identify defects or errors in the software and ensure that it meets the specified requirements and quality standards. They serve as a set of instructions or steps to be followed by testers to validate the behavior of the software under different conditions and scenarios. Test cases help in detecting and fixing bugs early in the development cycle, improving the overall quality of the software, and ensuring that it meets the expectations of the end-users.
