functionality.
Which of the following is the BEST testing technique?
It’s A because regression testing is designed to catch any issues caused by new code affecting old features, unlike stress or load tests which are all about system performance under pressure.
Makes sense to go with A for regression testing here. Stress and load focus on performance under heavy use, which doesn’t fit the goal. Quality (D) is too vague and doesn’t pinpoint the need to check old functions after new ones are added. Regression directly targets that.
A/B? Stress and load are more about performance limits, not verifying old stuff still works. Regression (A) specifically covers retesting existing features after changes.
A imo, stress and load don’t check existing features, regression does.
A/D? I agree regression (A) is the go-to for checking existing features after changes. But just to add, quality testing (D) is pretty broad and doesn’t specifically target verifying unchanged parts after new additions. Stress and load (B and C) focus on system performance under extreme conditions, so they don’t really help here. The question aims at functional stability, so regression fits best. It’s basically about rerunning previous tests to catch any unintended side effects from the new functionality.
A, regression is made for verifying existing features stay intact.
D imo, stress and load tests focus on performance under pressure, not functionality checks. Quality testing is too broad, so regression testing (A) fits best to catch any issues from new features.
Besides regression, I’d rule out stress and load since they’re about performance limits. Quality is vague too. So the focus has to be on testing that confirms nothing breaks after updates, right?
A, regression keeps old stuff working after changes.
