    To test valid requests, one should use '_assertResponseOk(response)' to get
    hints about failure reasons, if any.

    At least one test per operation type should test the complete response and
    behavior (HTTP, WebSocket, object updates, and object creations)
    Other tests of the same operation type can only assert the specific
    behavior differences.

    For invalid requests, response errors should be tested.
