pytest: How to get a list of all failed tests at the end of the session? (and while using xdist)

Question

I would like to have a list of all the tests that have failed to be used at the end of session.

Pytest lets you define a hook pyt

I came access this question, trying to figure out internal data structure for the session instance.

Iterating over session.items you can check rep_call.outcome for string representation of the test result.

def pytest_sessionfinish(session, exitstatus):
    for item in session.items:
        print('{} {}'.format(item.name, item.rep_call.outcome))

With trivial test cases you get this

test_positive passed
test_negative failed
