That’s expected, perform_job/3 doesn’t insert the job in the DB (it’s used to unit test a worker) so the id of the job will be nil
Yeah I verified this error with my own code and I was able to reproduce it.
Here’s what I strongly believe it’s going on:
:inlinetesting mode uses theOban.Queue.InlineEngine, which doesn’t touch the DB, while:manualtesting mode uses theOban.Queue.BasicEngine, which inserts jobs in the DBperform_job/3is always supposed to run in:inlinemode using theInlineEngine, if it accidentally uses theBasicEngine, the error you encountered will be triggered, namely it will try to update the state of a job that was never inserted in the DB- Therefore, when you call
perform_job/3, it setstesting: :inlinein the config here: oban/lib/oban/testing.ex at fdeb0001bbacb60c4686b86ca0610c7f7508d357 · oban-bg/oban · GitHub which is then used here: oban/lib/oban/config.ex at fdeb0001bbacb60c4686b86ca0610c7f7508d357 · oban-bg/oban · GitHub to enforce the usage of theInlineEngine(the correct one), regardless of thetestingmode set in your main config. So you can havetesting: :manualin your config and still haveperform_job/3run correctly using theInlineEngine. - This works well as long as you don’t use
with_testing_mode(:manual, ...). Reason is thatwith_testing_mode/2sets the engine to use in the process dictionary here: oban/lib/oban/testing.ex at 9b4861354f0189d548f4d5cd89273bc98f8eaede · oban-bg/oban · GitHub and this takes precedence over the engine set byperform_job/3. The overwrite happens here: oban/lib/oban/queue/engine.ex at 1e0f61a913a2ba52c985675383e2f7a180119ac5 · oban-bg/oban · GitHub
Long story short: perform_job/3 always tries to use the InlineEngine, cause it fails otherwise, but with_testing_mode/2 gets in the way end enforces the usage of the BasicEngine, which is the wrong one and causes the issue.
This seems to be a bug, perform_job/3 should ignore the engine set by with_testing_mode/2. Although, to be honest, I see little use for explicitly setting the test mode to :manual and then calling perform_job/3. If you’re using manual mode you’re expected to insert jobs in the DB and execute them with drain_queue/2.
