Question

I am trying to get started with unittest, but I am having a problem getting setUpClass() to work. Here is my test code…

import unittest

class TestRepGen(unittest.TestCase):
    """ Contains methods for training data testing """

    testvar = None

    @classmethod
    def setUpClass(cls):
        cls.testvar = 6

    def test_method(self):
        """ Ensure data is selected """
        self.assertIsNotNone(self.testvar,"self.testvar is None!")

# run tests
if __name__ == '__main__':
    unittest.main()

The assert error message is displayed, indicating that self.testvar == None, and has not been changed by setUpClass(). Is there something wrong with my code?

I get the same result if I run the code from within my IDE (Wing), or directly from the command line. For the record, I am using Python 3.2.1 under Windows7.

Ok – it’s hands-up time to admit that it was my mistake. I was using 3.1.2 when I should have been (and thought I was) using 3.2.1. I have now changed to the correct version, all is well and the test is passing. Many thanks to all who replied (and sorry for wasting your time 🙁 ).
