44 This test tests inner workings of the SAOP protocol, AKA 'white box' testing.
45 This adds brittleness to this test, because these internal workings may be
46 modified as long as the public API remains working. This approach was
47 necessary because fully testing the public API directly would lead to
48 excessive amounts of Mocking and unfocused tests. (with "focused test" we
49 mean that a junit test should test a small part of the code and thus aid in
50 locating the actual issue).
