Regression testing and sanity testing are both essential software testing techniques, but they serve different purposes in ensuring software stability after modifications. Regression Testing Definition: Regression testing is a comprehensive testing approach that ensures recent code changes do not negatively impact the existing functionality of an application. It involves re-running previously executed test cases to verify that the software still works as expected after modifications such as bug fixes, feature additions, or updates. Key Characteristics: Scope: Covers the entire application. Purpose: Ensures that new changes do not break existing functionality. Execution Time: Time-consuming due to extensive testing. Test Cases: Uses a large set of test cases. Automation: Often automated for efficiency. Depth: In-depth testing of all functionalities. When Used: After major updates, bug fixes, or new features. ...
