Thanks for the bug report.  This is something that may be rather difficult to fix so I don't know that we'll get to it anytime too soon but it's good to track these little differences.

Subject: [IronPython] Unit Test Failures Do Not Include String Arguments Passed to Test s

The following script
import unittest

class MyTest(unittest.TestCase):
    def testFirst(self):
        self.failUnless(False, 'first')
    def testSecond(self):
        self.failIf(False, 'second')

def suite():
    theSuite = unittest.makeSuite(MyTest, 'test')
    return theSuite;
if __name__ == '__main__':
produces the following output in Python 2.4
$ python unittesterror.py
FAIL: testFirst (__main__.MyTest)
Traceback (most recent call last):
  File "unittesterror.py", line 7, in testFirst
    self.failUnless(False, 'first')
AssertionError: first
Ran 2 tests in 0.000s
FAILED (failures=1)
(In particular, it contains the text 'first' supported to the assertion.)
Executing under IronPython, the output is:
$ /usr/local/bin/ironpython/IronPythonConsole.exe unittesterror.py
FAIL: testFirst (__main__.MyTest)

Ran 2 tests in 0.172s

In particular, the string argument is not present in the output.
I have submitted this behavior as a bug.
