The Travis version of
pytest seems to have been upgraded from
4.1.0 three days ago. Since then, all our test have been failing.
I was able to repro locally by installing
pytest-cov==2.6.0 which corresponds to the versions installed on Travis.
pytest-cov=2.6.1 fixes my build locally again, though.
Could you consider also upgrading
pytest-cov in Travis to fix things for us?
