New issue 740: internal error when parametrising using yield functools.partial
https://bitbucket.org/pytest-dev/pytest/issue/740/internal-error-when-parametrising-using
Dima Tisnek:
Traceback is far below.
Unfortunately I cannot yet create a minimum reproducible example, because
everything works, if I remove propitiatory code.
Note that all tests pass (I can remove all asserts even), but there's still an
internal error.
Below is the outline of the test:
```
#!python
import functools
backup = []
def setup():
backup[:] = secret, secret, secret
secret.init()
def teardown():
secret, secret, secret = backup[:]
def test_one(foo=123):
tmp = secret.secretObject()
tmp.init(...)
def test_all():
for somearg in range(10):
yield functools.partial(test_one, somearg)
```
```
#!python
(plc)[dima@bmg 18src]$ py.test -v test_foo.py
