object has no attribute '_memoizedcall' on pytest 6.x

[b0g3r]

Hi there! I started to use your library for one of my new projects and faced up with the exception like this:

tests/api/personal/test_change_password.py:None (tests/api/personal/test_change_password.py)
.venv/lib/python3.9/site-packages/pytest_describe/plugin.py:134: in _getobj
    return self._memoizedcall('_obj', self._importtestmodule)
E   AttributeError: 'DescribeBlock' object has no attribute '_memoizedcall'

I wrote a little example:

import pytest


@pytest.fixture()
def truelness():
    return True

def describe_pytest_describe():
    def should_work_on_pytest_6():
        assert True


def describe_pytest_describe_with_fixture(truelness):
    def should_work_on_pytest_6():
        assert truelness is True

output:

    return self._memoizedcall('_obj', self._importtestmodule)
E   AttributeError: 'DescribeBlock' object has no attribute '_memoizedcall'

During handling of the above exception, another exception occurred:
.venv/lib/python3.9/site-packages/pytest_describe/plugin.py:136: in _getobj
    return self._importtestmodule()

======================================================================================================= short test summary info ========================================================================================================

It looks like a problem with this specific commit in pytest: pytest-dev/pytest@ceb0165

Could you please take a look?

@b0g3r are you able to reproduce this with the unreleased version in the master branch?

[ROpdebee]

Not OP but can confirm the _memoizedcall error is gone on master for me (python 3.8.2, pytest 6.1.2). The example above still fails because the fixture isn't injected into the describe block, which I can reproduce on pytest 5.4.3 as well, although that may be a different issue.

[b0g3r]

Oops, my bad, my intuition told me that it should work like this 🙇‍♂️

[ROpdebee]

Fixture issue is related to #9 and #11, it's been a few years so it might be worthwhile to re-evaluate whether it'd be possible to inject fixtures into describe blocks (perhaps limited to class-scope fixtures?)

This should be fixed in 2.0. The fixture issue is now covered in #38. Any help with that one is appreciated.
