In testing my module for the first time, this error is reported

----------------------------------------------------------------------
Traceback (most recent call last):

but when I run it in the GUI, fattoreGiorni DOES WORK

I swear !

The problem is that both on_change functions return a None value and
python does not know how too substract None from None. That's because
the test suite call all on_change functions with an empty object to
ensure that they correctly work when there is no value on the form.

You should take in account None values on your function.

Thank you Sergi

I managed to give my date fiuelds default values AND make my methods return a date _anyway_.

That allowed the tests to pass
