Have you ever used git bisect? If so, how did you use it? Did it help you find a problem which would otherwise be difficult to find? Story time, I guess?

Several times, sometimes to find out when an incompatibility was introduced in an upstream dependency to find the maximum compatible version, but usually to find the commit that introduced a strange bug.

The process is always the same... Write a unit test, start bisect, check test select next bisect step, repeat. If your last-known-good and first-known-bad are correct, it always worked for me.
