No warning

Actual Behavior

PytestCollectionWarning raised

Steps to Reproduce

Using any static method from cdktf.Testing within a pytest test suite

Important Factoids

To my understanding the issue causes no issues in terms of functionality, only an annoying warning.

The issue stems from the the naming of Testing as pytest attempts to collect the class as a test class since it's name is prefixed with Test.

Just gave the the accepted answer at StackOverflow (__test__ = False) a quick test and unfortunately JSII does not allow properties starting with an underscore to be exposed to the other languages. So there's no simple way to get __test__ = False included in the generated Testing class in Python. Maybe there is another way to get __test__ into the __dict__ property of the Testing class, but I couldn't quickly find it.

Meanwhile to suppress warning you can create pytest.ini and add

[pytest]
filterwarnings =
    ignore:::.*.cdktf:11850

Thanks, @nlucansk

With cdktf 0.16.3, I had to update the above to be: ignore:::.*.cdktf:13637

Is the Testing class static? If yes, can it not just be converted into a module, say cdktf.testing?
