    P1000x this.

    I can read a diff.

    I need to know why.

    No, a code comment isn’t good enough, it’s out of date after the next commit.

      Code comments for "why"s that persist. Commits for why’s that are temporary.

      If you need to run X before Y, add a comment. If you added X before why because it was easier, leave it in a commit

          With a comment on the test detailing why it matters so people don’t just assume the test is out of date when it fails.

          And ideally test the underlying result of x before y, not the fact that x is called before y.

          And while we’re at it, assert in Y that X has been called, and again comment the reason for the preconditions.
