Hi,

This might not be the answer to your question, but you should be aware of this issue:

https://bitbucket.org/hpk42/pytest/issue/287/fixture-finalizer-failure-causes-other

Raising exceptions in the fixture teardown will make other fixtures not being teared down, which can cause other tests to fail.

Cheers
