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

Answer 1

I wanted a concise report of failed tests and parametrized variations so went with pytest_terminal_summary in conftest.py:

def pytest_terminal_summary(terminalreporter, exitstatus, config):
    terminalreporter.section('Failed tests')
    failures = [report.nodeid.split('::')[-1]
                for report in terminalreporter.stats.get('failed', [])]
    terminalreporter.write('\n'.join(failures) + '\n')

If you inspect terminalreporter._session.items, there's more information you can add to the report, this is just what I wanted.
