Have a way to force session scope teardown

[kalidasya]

Hi,

I have a session scope fixture what provisions vms in openstack. Sometimes something else during the setup goes wrong, or there is keyboard interruption or jenkins job is terminated (probably similar to keyboard interrupt) in these cases the teardown is not executed and the vms remain in openstack. It would be nice if there can be a way to force the execution of the teardown.

any update on this?

Hi @kalidasya, thanks for the ping on this.

There's nothing in pytest per-se, but you can take advantage of the fact that the finally block on a yield fixture will be guaranteed to be executed by Python:

import pytest

@pytest.fixture
def vm():
    try:
        raise ValueError
        yield 1
    finally:
        print('teardown')


def test(vm):
    pass

 pytest foo.py -q
E
=================================== ERRORS ====================================
___________________________ ERROR at setup of test ____________________________

    @pytest.fixture
    def vm():
        try:
>           raise ValueError
E           ValueError

foo.py:6: ValueError
---------------------------- Captured stdout setup ----------------------------
teardown
1 error in 0.03 seconds
