AttributeError: 'TestCaseFunction' object has no attribute 'addSubTest'.

Hello!

pyTest 7.4.4
pytest-odoo 1.0.0

For any test that is decorated with @tests.users such as:

from odoo import tests

...

@tests.users('demo')
def test_xxx(self):
    self.fail()

The tests actually runs with the specified user as self.env.user but the assertion failures always raise an additional AttributeError:

    @tests.users('demo')
    def test_xxx(self):
>       self.fail()
E       AssertionError: None

tests/test_xxx.py:52: AssertionError

During handling of the above exception, another exception occurred:

func = <function TestXXX.test_xxx at 0x7ff1a697e5f0>
args = (<odoo.addons.some_addon.tests.test_xxx.TestXXX testMethod=test_xxx>,)
kwargs = {}
self = <odoo.addons.some_addon.tests.test_xxx.TestXXX testMethod=test_xxx>
old_uid = 1, Users = res.users(), user_id = {'demo': 3}
login = 'demo'

    @decorator
    def _users(func, *args, **kwargs):
        self = args[0]
        old_uid = self.uid
        try:
            # retrieve users
            Users = self.env['res.users'].with_context(active_test=False)
            user_id = {
                user.login: user.id
                for user in Users.search([('login', 'in', list(logins))])
            }
            for login in logins:
>               with self.subTest(login=login):

Not a huge deal, but having to scroll up to the actual assertion error is a bit anoying ;) Can this be fixed?

Something related to subtests has been mentioned in #67

Could you add more context it's like your TestXXX class is not a subclass of unittest.TestCaseand probably better to use a base Test case class from odoo.tests.common. Could you confirm?
