Ace the 2025 Software Quality Assurance Challenge – Elevate Your Testing Skills!

The main focus of regression testing is to confirm that recent changes haven't introduced new bugs. Regression testing is performed after modifications have been made to the software, such as bug fixes or new features, to verify that these changes did not adversely affect the existing functionality of the application. This testing ensures that previously functioning parts of the software continue to work as expected after the introduction of new code, which is crucial for maintaining software reliability and quality over time.

Each of the other options addresses different aspects of software testing: performance testing concentrates on how the application behaves under various loads, compliance testing ensures that the software adheres to specific regulatory requirements, and usability testing evaluates how user-friendly the software is. While these are all important for overall software quality, they do not specifically target the purpose of regression testing, which is fundamentally about safeguarding existing functionality after changes are implemented.
