Which test is done to check that the new technology remains consistent with the old one?

Correct answer: Regression Test. Regression testing checks that new changes have not broken existing features.

Background: Regression tests are rerun after every update.

• Unit test: Unit testing checks small parts of code.
• Integration test: Integration testing checks that modules work together.
• Smoke test: Smoke testing is a quick basic check of the build.

Did you know? “Regression” means going back to check old features.

Memory trick: Regression = check old still works.
