Regression Testing
Regression Testing is like a safety check that makes sure software still works correctly after changes are made. Think of it as double-checking that fixing one thing hasn't accidentally broken something else that was working before. It's similar to how a mechanic might check all car systems after replacing a part to ensure everything still runs smoothly. This type of testing is essential in software development because it helps catch unexpected problems before customers find them. When you see this term in resumes, it usually means the person has experience in maintaining software quality and preventing issues from reaching end users.
