According to https://pypi.python.org/pypi/fixtures, prior to
version 1.3.0 fixtures recommended overriding setUp. This is
still supported, but since it is harder to write leak-free
fixtures in this fashion, it is not recommended. We should
override _setUp now.
Make sure the policy enforce_wsgi decorator is called.
Make sure the request will be disallowed by policy, when it does not
satisfy the policy rule.
