As discussed in pytest-dev/pytest#3973, pytest 3.8.0
introduced some code that ends up checking the
cwd
by accident. One ofthe tests in your test suites changes the
cwd
to a temporary directory, andthis blows up some tests after it.
This change uses the
monkeypatch
fixture to safe cwd-switching, byrestoring it to the original value at the end of the test.
