Python unit test with base and sub class

Question

I currently have a few unit tests which share a common set of tests. Here\'s an example:

import unittest

class BaseTest(unittest.TestCase):

    def testCo         


        

Answer 1

What are you trying to achieve? If you have common test code (assertions, template tests, etc), then place them in methods which aren't prefixed with test so unittest won't load them.

import unittest

class CommonTests(unittest.TestCase):
      def common_assertion(self, foo, bar, baz):
          # whatever common code
          self.assertEqual(foo(bar), baz)

class BaseTest(CommonTests):

    def testCommon(self):
        print 'Calling BaseTest:testCommon'
        value = 5
        self.assertEquals(value, 5)

class SubTest1(CommonTests):

    def testSub1(self):
        print 'Calling SubTest1:testSub1'
        sub = 3
        self.assertEquals(sub, 3)

class SubTest2(CommonTests):

    def testSub2(self):
        print 'Calling SubTest2:testSub2'
        sub = 4
        self.assertEquals(sub, 4)

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