For example wendelin.core 2 uses pytest_unconfigure to unmount wcfs servers that it spawned:
https://lab.nexedi.com/kirr/wendelin.core/blob/1be4d730/conftest.py#L27-53
This usually leads to some test as shown in added test.
-> Skip that text backwards and actually detect pytest summary line instead of returning empty dict, because empty dict forces Nexedi ERP5 to treat such test run to have UNKNOWN status, e.g.
