What exactly are we testing at that point?

  Ensuring that `if x == 1` works when x == 1. Very important. Very valuable. Imagine if `if err != nil { return err }` just stopped working tomorrow. Your tests would detect it! Outage prevented!

    You're being sarcastic but honestly, I've never found a regression because of a unit test. Only past few days though, I did find two bugs that would've been prevented if the original code was covered by a decent unit test.

      > You're being sarcastic but honestly, I've never found a regression because of a unit test So you've never made a change caused a unit test to fail? If not, how large is your codebase, and is ownership shared across multiple teams? I caught dozens of latent or unreported bugs by writing unit tests for a 6kloc JS app which had 0% coverage before.

    I don't write Perl or Ruby anymore, but this would have been immensely helpful back then.
