I’ve created a PR for updating the test_host_connection_pool class with the magic attribute __test__ = False (superclass) and __test__ = True (subclasses). This allows the test to run (and should also be backward compatible with Nose).

Unit tests now run successfully with ‘pytest tests/unit’

FTR the “NoneType is not callable” stuff is discussed more thoroughly in

You can use the skip decorator to skip tests or classes.

@pytest.mark.skip(reason="no way of currently testing this")

def test_func_one():

Or consider renaming these functions without the test_ prefix.

Current status for running tests with pytest:

8 tests fail, 7 of which are from test_host_connection_pool.py because it is trying to run functions named “test_…” and aren’t actually tests to be run. Need to bypass this superclass so pytest doesn’t try to run these.

This work will hopefully be included in the the 3.27.0 release which we’ll start working on after we “clear the decks” and get an initial new release out containing the changes that have gone into master but haven’t been included in a release yet. No guarantees but that’s certainly our hope.

Additional note: we’ll want to make sure pytest works correctly with every version of the Python runtime we aim to support. Note as an example, although in that case it’s nose (and I suspect that’s more of a maintenance issue than anything).
