Writing Unit Tests in Python ✅

1.Simple and easy just import the Python 3 built-in library unittest.
2.Wrap up tests in a Class.
3.Use assert methods.
import unittest
​
class TestSum(unittest.TestCase):
​
    def test_sum(self):
        self.assertEqual(sum([1, 2, 3]), 6, "Should be 6")
​
    def test_sum_tuple(self):
        self.assertEqual(sum((1, 2, 2)), 6, "Should be 6")
​
if __name__ == '__main__':
    unittest.main()
