Still no good, I scanned the test fetcher and found a potential bug. COuld you add
```py
            elif f.startswith("examples/tensorflow"):
                test_files_to_run.append("examples/flax/test_tensorflow_examples.py")
```
at the line 562 of `utils/test_fetcher.py` (in-between PyTorch and Flax)? I think that's what causing the issue of the tests not running.

> It looks like your branch is a bit old and does not contain some fixes made to make sure the example tests run when an example is modified (you can see the test examples are not running here 😅 ). Could you try a rebase on main?

@sgugger I've rebased from upstream main and force pushed again. If I run `git log --oneline` I can see these changes are applied on top of the tip of main.

The examples still aren't running and I can't see in the diff where I could be overriding this 😅 I'm sure there's something I'm overlooking. I'll keep digging but let me know if there's something else I should be doing. Sorry to bother.

@sgugger - sorry late on the comment as well. I'll add your suggestion!

Hey @amyeroberts, is this PR still going ahead? It looked almost ready!

@Rocketknight1 Yes - sorry, this fell down my priority list for a bit. Code is all ready to go - I was trying to find models that make the tests run quickly c.f. [this comment](https://github.com/huggingface/transformers/pull/19956#discussion_r1012991408). 

@amyeroberts Ah, that makes sense! It's totally okay to upload your own super-mini model and use that - it doesn't really matter if the accuracy is bad, the test will just let us detect if the outputs from this model class change suddenly
