Comment:

I was able to reproduce the behavior on my NixOS development machine with a 3.13.9 CPython.

Replacing all occurrences of failUnlessRaises with assertRaises fixes this problem.

     92025-12-30 20:53:20 hacklschorsch   Seems most failures here are due to "[...] object has no attribute 'failUnlessRaises'" - Maybe some dependency has changed?

     112025-12-30 20:55:38 hacklschorsch   IIRC these worked until a while ago
     122025-12-30 21:43:49 sajith  hacklschorsch: I am not 100% sure right now, but I think Python (unittest module maybe?) has deprecated failUnlessRaises in favor of assertRaises or something, and I suspect that we've ended up importing failUnlessRaises both from twisted.trial.unittest and stdlib unittest. Just a hypothesis. I don't have the time to check right now.
