OK

The methods you want to be tested should start with test

class TestNumberMethods(unittest.TestCase):
    def test_addition(self):
        print(cal.addition())
        self.assertNotEqual(cal.addition(),4)
        self.assertTrue(cal.addition())
        #self.assertEqual(cal.addition(),3,"Should be 4")
