PyTest - Apply mock to all tests

I would like to apply a mock/patch that will apply to all tests, how can I do this?

I had tried putting it in a fixture, and using the fixture everywhere, but, the reapplication of the mock/patch on each test was leading to inconsistent id(my_mock) values.

You can make a fixture applied only once for all the test suite execution by scoping the fixture to 'session', and using it in all your tests:

import pytest
from unittest import mock

@pytest.fixture(scope='session', autouse=True)
def my_thing_mock():
    with mock.patch.object(TheThingYouWantToMock, 'some_attribute') as _fixture:
        yield _fixture
