This looks like a bug in pytest to me. The "offending" code in
t1_backends.py is:
def pytest_generate_tests(metafunc, _info_cache=[]):
# [ Populate test_params ]
metafunc.parametrize("backend", test_params, indirect=True,
ids=[ '%s/%s' % (x[0].name, x[1])
for x in test_params] )
I believe this should succeed, no matter the contents of test_params.
Best,
