IMO there is no "correct" way regarding order of calling test functions. 
People even have written randomizers so that implicit (and often unintended) 
sife effects of test functions depending on other test functions are uncovered.  
If you are starting to get into testing with Python, i'd join Michael and 
others here and recommend to not depend on test ordering at all.
