Test Cases
Test cases are detailed specifications that define inputs, execution conditions, and expected outcomes for testing software functionality. They are used to verify that a system or component behaves as intended under various scenarios, helping to identify defects and ensure quality. Test cases are typically documented and executed as part of systematic testing processes like unit, integration, or system testing.
Developers should learn and use test cases to improve software reliability, catch bugs early in the development cycle, and facilitate regression testing. They are essential in agile and test-driven development (TDD) environments to ensure code changes don't break existing functionality. Use cases include validating new features, automating repetitive tests, and meeting compliance or quality standards in industries like finance or healthcare.
