Error discovering pytest too aggressive

[isidorn]

Testing #17040

1. Follow steps in the test plan item to setup pytest
2. Start typing your test in the file
3. As you are typing the following:

def test_math2():
    

4. Notice an error in the Test view

The error reporting should be less aggressive. While the user is in the process of writing a test he or she should not be bothered with errors. I suggest the following heuristic:

• While there are some tests discovered in the file do not show this error. Only show this error if the user explicitly clicks on the Run Tests action

@isidorn Were you just typing or did you hit save or do you have autosave?

I have autosave. I was typing.
