New issue 498: Function scope fixture with failing finalizer called only once
https://bitbucket.org/hpk42/pytest/issue/498/function-scope-fixture-with-failing
Alexander Steinert:
``` python
import pytest
class Helper:
pass
@pytest.fixture(scope="function")
def failing_fixture(request):
helper = Helper()
def fin():
raise RuntimeError("On purpose!")
request.addfinalizer(fin)
return helper
def test_0(failing_fixture):
print("test_0", failing_fixture)
def test_1(failing_fixture):
# In pytest 2.3.5 and 2.5.2, this test gets the same helper instance like
# test_0 and the fixture's finalizer is not called.
print("test_1", failing_fixture)
assert 0
```
```
