The reason for that is that the unit testing framework catches and 
handles the error. It calls both test functions in some unspecified 
order and logs the result. Calls to two separate test functions are 
thereby separated from each other. This is intentionally so, but I think 
you can also give the unit testing framework a flag that makes it abort 
after the first error. In no way will the exception escape from the 
unittest.main() call though, it is all caught and handled inside, also 
by intention.

I don't understand what you want to say here. I also don't understand 
what your problem in general is. I guess there are some expectations 
which are not satisfied, but you haven't explained those explicitly yet.
