Grouping all tests Python
Question:   
I have 2 modules: test1.py and test2.py.  
**test1.py**

    
    
    import unittest
    
    class ArithTest (unittest.TestCase):
    
        def test_run (self):
    
            """ Test addition and succeed. """
            self.failUnless (1+1==2, 'one plus one fails!')
            self.failIf (1+1 != 2, 'one plus one fails again!')
            self.failUnlessEqual (1+1, 2, 'more trouble with one plus one!')
    
    if __name__ == '__main__':
        unittest.main()
    

**test2.py**

    
    
    import unittest
    
    class AlgTest (unittest.TestCase):
    
        def test_alg (self):
    
            """ Test addition and succeed. """
            self.assertEqual(1+1, 2, '1+1 != 2? whaaat?')
            self.assertEqual(6-5, 1, '6-5 != 5 wft python?')
    
    if __name__ == '__main__':
        unittest.main()
    

* * *

**-Now-** I wanna create a new module test3.py to test test1.py and test2.py.
I don't now how, i read on internet about suit tests but i don't understand. I
don't want to create one more method with calling tests, and call them on
test3.py. I wanna group them and call in test3.py and they run as unitests


Answer: test1.py

    
    
    import unittest
    
    class ArithTest (unittest.TestCase):
    
        def test_run (self):
    
            """ Test addition and succeed. """
            self.failUnless (1+1==2, 'one plus one fails!')
            self.failIf (1+1 != 2, 'one plus one fails again!')
            self.failUnlessEqual (1+1, 2, 'more trouble with one plus one!')
    
        def runTest(self):
            self.test_run()
    
    if __name__ == '__main__':
        unittest.main()
    

test2.py

    
    
    import unittest
    
    class AlgTest (unittest.TestCase):
    
        def test_alg (self):
    
            """ Test addition and succeed. """
            self.assertEqual(1+1, 2, '1+1 != 2? whaaat?')
            self.assertEqual(6-5, 1, '6-5 != 5 wft python?')
    
        def runTest(self):
            self.test_alg()
    
    if __name__ == '__main__':
        unittest.main()
    

test3.py

    
    
    from .test1 import ArithTest
    from .test2 import AlgTest
    import unittest
    
    def suite_2():
        suite = unittest.TestSuite()
        suite.addTest(ArithTest())
        suite.addTest(AlgTest())
    
        return suite
    
    if __name__ == '__main__':
        runner = unittest.TextTestRunner()
        test_suite = suite_2()
        runner.run(test_suite)
    

Also add a `__init__.py`

Run it with `python3 -m folder_name.test3`
