What is the main purpose of developing test cases?

The primary purpose of developing test cases is to cover all test conditions. Test cases are detailed, step-by-step instructions designed to verify specific functionalities or features of the software under test. By creating these cases, testers ensure that various input scenarios, functional requirements, and edge cases are systematically checked, allowing for thorough verification of the software's behavior and performance.

Designing test cases helps in establishing a clear understanding of what to test and how to evaluate the outcomes. This structured approach not only aids in identifying defects but also ensures that the software meets the specified requirements and functions as intended in different scenarios. Covering all test conditions through well-defined test cases is essential for achieving a high level of software quality, as it minimizes the risk of overlooked issues in the final product. Thus, the main objective of developing test cases directly aligns with achieving comprehensive testing coverage.
