Bug#980842: pytest-mpi: Tests test_mpi_with_mpi and test_mpi_only_mpi fail

[Drew Parsons]

Source: pytest-mpi
Version: 0.4-3
Severity: normal
Control: forwarded -1 https://github.com/aragilar/pytest-mpi/issues/14

After applying upstream PR#12 (https://github.com/aragilar/pytest-mpi/pull/12)
in debian/patches/fix_pytest6_PR12.patch, tests test_mpi_with_mpi and
test_mpi_only_mpi still fail with pytest 6.0.2-2.

An error "ValueError: mpi mark does not take positional args" is
easily fixed with
-    @pytest.mark.mpi(2)
+    @pytest.mark.mpi(min_size=2)
     def test_size_fail_pos():
in tests/test_markers.py

But then there are other errors:
$ python3 -m pytest -k "test_mpi_with_mpi or test_mpi_only_mpi" -p pytester -vv
...

Likewise for test_mpi_only_mpi.
