unit testing - Execution order on Python unittest

Question

I need to set an order of execution for my tests, because I need some data verified before the others. Is possible to set an order?

class OneTestCase(unittest.TestCase):
    def setUp(self):
        # something to do
    def test_login (self):
        # first test
        pass
    def test_other (self):
        # any order after test_login
    def test_othermore (self):
        # any order after test_login
if __name__ == '__main__':
    unittest.main()

Answer 1

You can do it like this:

class OneTestCase(unittest.TestCase):
    @classmethod
    def setUpClass(cls):
        # something to do
        pass

    def test_01_login (self):
        # first test
        pass
    def test_02_other (self):
        # any order after test_login
    def test_03_othermore (self):
        # any order after test_login

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

Tests are sorted alphabetically, so just add numbers to get your desired order. Probably you also want to set failfast = True for the testrunner, so it fails instantly, as soon as the first test fails.
