[Pyunit-interest] problem using assertRaises

[robin a. j. <rob...@ea...>]

Hello,

I'm using the unittest module shipped with PythonWin 2.2.1, and I am =
having trouble using assertRaises.  Here is a code fragment example.


      def test_01(self):
         '''handling the failure to connect with and log onto a FTP =
server'''
          try:
             self.testable.open()
          except Exception:
             pass
          else:
             self.fail('exception not raised')

      def test_02(self):
         '''handling the failure to connect with and log onto a FTP =
server'''
         self.assertRaises(Exception, self.testable.open())

test_01 works as expected (i.e., when the open() operation fails, the =
test succeeds).

However, test_02 does not work as expected; when the open() operation =
fails, the test also fails (i.e., the exception is not caught by =
assertRaises).

What am I doing wrong?
