yield <step-name> does not work without extra yield at the top of the test case about python-pytest-steps HOT 2 OPEN

Digging deeper into this matter, it looks like the steps are handled differently inside VSCODE and when run on the commandline.

When running the above snippet in VSCODE an extra yield at the top works fine although the steps are enumerated in random order in the drop down menu of VSCODE. I extended the test case from the documentation:

Starting the test case in VSCODE, they are started like this without the first yield

> ./.venv/bin/python -m pytest --rootdir . --override-ini junit_family=xunit1 --junit-xml=/var/folders/pt/zw8ycd8x1pl7w13s9ltgrvlc0000gq/T/tmp-361377bjf1ByIrKIL.xml ./tests/integration/apis/test_user_files.py::test_suite[4.step_d] cwd: .
I.e. one line per step, repeated In the order d,e,b,a,c.

And fails with:
´./tests/integration/apis/test_user_files.py::test_suite[3.step_c] Failed: [undefined]pytest_steps.steps_generator.StepYieldError: Error collecting results from step '3.step_c': received '1.step_a' from the yield statement, which is different from the current step or step name. Please either use yield, yield '3.step_c' or wrap your step with with optional_step(...) as my_step: and use yield my_step´

Running the same test case from the command line with ´pytest´ works fine though.

This is actually a huge problem for us using VSCODE and a CI/CD pipeline. Any suggestions or ideas are more than welcome!

Hi @danielFlemstrom, thanks for reporting !
It seems indeed very much related to VSCode...
Proably the best and fastest workaround is to get rid of pytest steps and instead passing a session-scoped fixture to all of your "steps" tests. You can then further use a basic test class to wrap the various "step" tests, if you want to have them nicely separated from others.

That's the easiest workaround I would suggest, not requiring strong investigations on how VSCode inspects pytest (which I do not have the bandwidth to perform as of now unfortunately)

I hope this helps!
