Issue happened only once, as far as I know. I will update this issue if it happens multiple times and if I manage to reproduce it outside of GitHub Actions CI.

[RonnyPfannschmidt]

@bluetech there is a disparity in how we get the objects for testcase objects and for normal python tests

the normal case in testcase intentionally passes name, the traceback cutting case will however occasionally trigger making a new instance without adding the object

i wonder how how to best make this fit/change

a quickfix is likely going to need a test for unittest Testcase objects and a own _get_obj implementation

[The-Compiler]

It’s probably as @RonnyPfannschmidt says due to the Instance collector removal, and it shouldn’t be hard to make it work again.

Correct - bisected to 062d91ab474881b58ae1ff49b4844402677faf45 (“python: remove the Instance collector node”, #9277).
