Which type of testing is primarily conducted to ensure that recent changes to the codebase have not introduced new defects into existing functionalities of a software application?
Performance testing
Regression testing
Stress testing
Unit testing
Regression testing is conducted to verify that recent code changes have not adversely affected existing functionalities. It ensures that the software continues to operate as intended after modifications. Unit testing focuses on individual units or components of the software in isolation. Stress testing assesses the system's performance under extreme conditions to determine its stability. Performance testing measures the system's responsiveness and speed under a specific workload but does not specifically target issues arising from recent code changes.
