Subject: [PATCH v2 2/4] kunit: tool: stop using bare asserts in unit test
Use self.assertEqual/assertNotEqual() instead.
Besides being more appropriate in a unit test, it'll also give a better
error message by show the unexpected values.
Also
* Delete redundant check of exception types. self.assertRaises does this.
* s/kall/call. There's no reason to name it this way.
* This is probably a misunderstanding from the docs which uses it
since `mock.call` is in scope as `call`.
