Question

I need to run a Python unittest test suite against multiple REST backend resources so I need to pass in a Resource object to the test suite and individual testcases.

Is setting a global var the right way to do this, or is there a better way?

resource = Resource(‘http://example.com’)

class RestTestCase(unittest.TestCase):
    def setUp(self):
        self.resource = resource

def suite():
    suite = unittest.TestSuite()
    suite.addTest(unittest.makeSuite(RestTestCase))
    return suite

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

Follow the example of the how the standard library writes its own unittests. Put the resource in a class variable and use inheritance to test the various resources:

class RestTestCase(unittest.TestCase):
    resource = Resource('http://example.com')

    def sometest(self):
        r = self.resource
        ...
        self.assertEqual(expectedresult, actualresult)

class SomeOtherRestTestCase(RestTestCase):
    resource = Resource('http://someother.example.com')

class YetAnotherRestTestCase(RestTestCase):
    resource = Resource('http://yetanother.example.com')

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