I'm sorry, I don't understand what you mean by "on intention".

Are you using the Python unittest module, or C++ unit tests?

Python's unittest catches and suppresses exceptions, so it should not be 
printing exceptions except as part of the normal unittest output.

If your unit tests are raising exceptions, your tests are broken. They 
should either raise expected exceptions, in which case the exception is a 
passing test, or they are failing tests, or they are bugs in your test 
code. Fix the failing tests and the bugs in the test code, don't hide 
them.
