Its almost impossible to say since we don;t know what you re doing in 
your tests script. Assuming you just call it using subprocess or
similar then its next to impossible since you are launching another 
process. The best bet in that case is to insert print statements but 
that then modifies the code which is not ideal in a test environment.

Breakpoints will only work in the process you are running in the IDE.
We would need to see how the test script works to advise further. There 
are several options, none of them particularly easy.

If you want to debug clickurl.py it would be better to work on it 
directly and just use the tests script to identify the need to
debug it.
