unittest assertRaises Problem

[john]

All:

Hi. I am an experienced developer (15 yrs), but new to Python and have
a question re unittest and assertRaises. No matter what I raise,
assertRaises is never successful. Here is the test code:


class Foo:
    def testException(self):
       raise ValueError

class FooTestCase(unittest.TestCase):

       testTryThis(self):
          f = Foo()
          self.assertRaises(ValueError, f.testException())

This fails --- unittest reports the following:
FAILED (errors=1)

This seems like the most basic thing in the world. I am running Python
2.5 on Windows XP using Eclipse and PyDev

Any help appreciated.

Thanks,
John
