def matches(self, testString, parseAll=True):
        """
        Method for quick testing of a parser against a test string. Good for simple 
        inline microtests of sub expressions while building up larger parser.

        Parameters:
         - testString - to test against this expression for a match
         - parseAll - (default=C{True}) - flag to pass to C{L{parseString}} when running tests

        Example::
            expr = Word(nums)
            assert expr.matches("100")
