Thanks for the tips. For most I have to read a ‘little’ first, so I
will not implement them immediately.
Another question. Is it acceptable to have it in the module itself, or
should I put it in something like test_<module>.py? The code for
testing is bigger as the code for the implementation, so I am leaning
to putting it in a separate file.
