PyTest fixtures using addfinalizer() become convenient when you want to
make them work in RobotFramework as well.
def fixture_being_used_in_robotframework():
closure = "details of how to cleanup the fixture"
def clean_up():
print(closure)
return clean_up
@pytest.fixture()
def reuse_robotframework_fixture(request):
request.addfinalizer(fixture_being_used_in_robotframework())
