Problem with Unittest

[mhanusek]

Hello!
I have a problem with calling method - assertTrue.

My code:

#!/usr/bin/env python3

import unittest

class MyTest(unittest.TestCase):

    @classmethod
    def setUp(self):
        cond = True
        self.assertTrue(self, expr=cond) # its working
        self.assertTrue(cond) # its not working - TypeError: assertTrue() missing 1 required positional argument: 'expr

    def test_1(self):
        pass

if __name__ == '__main__':
    unittest.main(failfast=True)

Don't decorate setUp as a classmethod. That's not the way it is supposed to work. Also normally assertions belong to the test methods not the setUp method.
