Regression tests in review

A PR fixing a bug in a beauty appointment app got a review comment saying there's no reproduction test. The reviewer has already read the code and could approve it, so why ask for a separate reproduction test?

How would an interviewer hear this answer? You'll see whether they'd move on, dig in, or say no, and which sentences would trip you up. Your score doesn't change.

A reviewer's approval is one human judgment about today's diff, while a reproduction test catches the regression automatically from any later change if the same input brings the bug back.
