In `test_contained_in` and other tests, assert more data instead of just the `passed` key

Is your feature request related to a problem? Please describe. Not related to functionalities of the program, only to make the testcases more robust and reliable.

Describe the solution you'd like Most of the test cases only assert the passed key and not all of the key, it's best to actually assert most of the keys available so that we know between evaluation that is actually failing or is not evaluated. One example of this would be in test_contained_in

@mark.passing
@mark.parametrize("evaluator_input,evaluator_data", checks_passing)
def test_evaluate_passing(evaluator_input, evaluator_data):
    result = evaluator.evaluate(evaluator_input, evaluator_data)
    assert result["passed"] == True  # {"passed": True, "message": f"Found {evaluator_input} inside {evaluator_data}"}

We have to at least assert as well the message key.
