Add `ast.AsyncFunctionDef` to correctly recognize async test methods.

[accoleon]

• Added ast.AsyncFunctionDef to discovery
• Tested on my own code, while existing tests pass (other than the 5 failing ones that happened on fork)

Resolves #62

[gleb-sevruk]

Great addition, I will do minimal testing and merge it tomorrow.

[gleb-sevruk]

Can you actually run async test? I got

        if events._get_running_loop() is not None:
>           raise RuntimeError(
                'Cannot run the event loop while another loop is running')
E           RuntimeError: Cannot run the event loop while another loop is running

And need to dig deeper

Side note -> tests are now discovered, and thats excellent

[accoleon]

I did - however the actual running of the async tests required nest_asyncio as described in https://github.com/gleb-sevruk/pycrunch-engine/issues/52#issuecomment-908045411 - I didn't look further into the async system unfortunately. That will come next time!

[gleb-sevruk]

I got it working via next-asyncio in pycrunch/multiprocess_child_main.py

import nest_asyncio
nest_asyncio.apply()

preparing a fix

Seems up and running now: https://github.com/gleb-sevruk/pycrunch-engine/pull/101

🙌

Thanks a lot; Version 1.6.1 Is published; Let me know about the experience.

https://pypi.org/project/pycrunch-engine/1.6.1/

[gleb-sevruk]

You will need to enable plugins in .pycrunch-config.yaml for this to work

engine:
  load-pytest-plugins: true

[accoleon]

Yep! Just tested 1.6.1 and works great. Pretty awesome, I loved ncrunch when I was working in .NET and have been looking for something for Python ever since!

[vegaroy13]

Oh Thank You. Just update to back front last updates (1.6.1) and works over python 3.10. Previous versions of python will fail due to syntax updated code not supported.

[gleb-sevruk]

@vegaroy13 Oh I see what you mean

I will do another version with typing.Union to make sure it can still work on 3.9

[gleb-sevruk]

Version 1.6.2 uploaded to pip; should resolve compatibility issues with Python 3.9
