Pytest 4.1.0 has just been released, removing a number of features.

Could it be this?

pytest-dev/pytest#4546: Remove Node.get_marker(name) the return value was not usable for more than a existence check.

Use Node.get_closest_marker(name) as a replacement.

Another project to run in to this (matplotlib/matplotlib#13121) notes it's an issue with pytest-cov: pytest-dev/pytest-cov#253.

If there's not a pytest-cov release soon, we can temporarily pin pytest<4.1, like matplotlib/matplotlib#13122.

pytest-cov 2.6.1 has been released. Re-running tests, this now passes.
