Hi, Ralph
Agree on that. I'd like to have a comment in the test, specially for
this line where you're checking for non-existing classes. It does not
seem to be obvious what should be tested here (at least it was not
obvious for me). This may make it easier to fix stuff if this test
should fail in future.
I don't know if this here is the right test to put the comment in, but
it's at least relying on something global that may change.
Thanks for giving me a deeper knowledge here :)
Bye
Simon
