We have a lot of test failures.
Most are innocent: due log files made obsoletee by code changes.
This kind of thing should be eliminated: it makes using the tests much
harder for everyone else.
It is understandable that this happens once in a while. But these
divergences must be fixed ASAP. We seem to let them drag on for a long
Ideally, one should check in test log updates with the code change that
causes them. Of course one should be careful: we don't want to bless a
bug. Part of making a change is being sure that the new log is correct.
Before checking it in.
I too often check in changes without testing. That's because testing is
so unwieldy. This is a circular problem: test failures that I might have
caused get lost in the noise of endemic failure.
Testing matters. Let's make it great again.
