I wouldn't call attributes "implementation details", at least not in 
Python.  And while it is true that unit tests might not find the 
misspelling *directly* (i.e. you rarely test if you have misspelled 
something), your tests should definitely show unexpected behavior and 
results, if that attribute is of any importance.  Otherwise there's a 
loophole in your tests. :-)
