Outputting data from unit test in Python

Question

If I\'m writing unit tests in python (using the unittest module), is it possible to output data from a failed test, so I can examine it to help deduce what caused the error?

Answer 1

Expanding @F.C. 's answer, this works quite well for me:

class MyTest(unittest.TestCase):
    def messenger(self, message):
        try:
            self.assertEqual(1, 2, msg=message)
        except AssertionError as e:      
            print "\nMESSENGER OUTPUT: %s" % str(e),
