I don't understand the need for the snarky comment, LLMs can run the test suite and avoid regressions.
A change can introduce regressions in any large project even if 100% of unit tests pass. Unit tests test individual units, regressions can happen at many levels. Especially if we treat performance degradations as regressions.
