New issue 213: Issue with numpy arrays and pytest.mark.parametrize
https://bitbucket.org/hpk42/pytest/issue/213/issue-with-numpy-arrays-and
astrofrog:
The following tests used to pass:
```
import pytest
import numpy as np
@pytest.mark.parametrize(('error'), [1., 'spam', np.ones((5, 5))])
def test(error):
pass
```
but in the latest tip (5de7185c2891) I get the following exception:
```
