pytest: TestCase failures reported as passing

Reproduce the issue with the shown TestCase example and the ciqueue.pytest_report plugin command. Read the pytest unittest hook referenced in the issue and the ciqueue reporting hook to verify their ordering and handling of call.excinfo. Done means a failing TestCase is reported as failed rather than passed.

With this test suite:

# test_example.py
from unittest import TestCase

class TestExample(TestCase):
    def test_fail(self):
        assert False

Running works as expected:

$ pytest -p ciqueue.pytest --queue 'redis://localhost:6379/0?worker=0&build=repro&retry=0&timeout=10' test_example.py
========================================================= test session starts =========================================================
platform darwin -- Python 2.7.13, pytest-4.0.1, py-1.7.0, pluggy-0.6.0
...

test_example.py F

============================================================== FAILURES ===============================================================
________________________________________________________ TestExample.test_fail ________________________________________________________

self = <test_example.TestExample testMethod=test_fail>

    def test_fail(self):
>       assert False
E       AssertionError: assert False

test_example.py:5: AssertionError
====================================================== 1 failed in 0.06 seconds =======================================================

However, reporting shows that the test passed:

$ pytest -p ciqueue.pytest_report --queue 'redis://localhost:6379/0?worker=0&build=repro&retry=0&timeout=10' test_example.py
========================================================= test session starts =========================================================

test_example.py .                                                                                                               [100%]

====================================================== 1 passed in 0.02 seconds =======================================================

This appears to be due to ciqueue's makereport triggering before the one in pytest which is responsible for setting call.excinfo for TestCase-style tests.

From these docs it looks like:

1. the ordering of multiple tryfirst=True hooks is undefined
2. hookwrapper=True can execute code before a tryfirst hook

So, one fix could be to get pytest to switch to using hookwrapper. I figured I'd raise it with you folks first, though, in case it's something that's easier to fix on this end (by making ciqueue execute later, somehow).
