pytest mocker assert has_calls

 Managed to figure it out with the help of another answer provided by the author of pytest-mock.

The assert should be called as follows if using alt. A: mock_a.assert_has_calls([mocker.call(mocker.ANY, 100), mocker.call(mocker.ANY, 50)])

Posting this to help others.
