For some reason I had a test who suddenly failed, mix test test/pleroma/web/o_auth/app_test.exs:54. A user has a list of applications and this test adds them and then sees if the list it gets back is the same as the apps it added.
When I ran mix test a day before I didn't have this problem and when I pushed code today in a different MR, the pipeline succeeded (see https://git.pleroma.social/ilja/pleroma/-/jobs/205827), yet locally it failed. So it seems the test can sometimes succeed and sometimes fail, which makes it untrustworthy.
The failure I see is because the returned list is in reverse order. I assume that's not per sé wrong. You just want to know if the apps you added are actually there. I fixed the test by first ordering the lists before comparing.
AFAICT (and as far as that's relevant) the test got introduced in commit cb2a072e62
In general, tests that match these criteria can be made async:
- Doesn't use real Cachex.
- Doesn't write to the Config / Application Environment.
- Uses Mock. Using Mox is fine.
- Uses the streamer.
