Answer 1

import unittest

class UnitTestExamples(unittest.TestCase):

    def testsum(self):
        a = 10
        b = 42
        self.assertEqual(a+b,52)

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

Run the above in with your python interpretor using -v flag.

python testexample.py -v

And you will see that testsum is run and the test is exercised. unittest documentation has details how the working and the above example should be simple enough to get you started. The methods which start with the name test are run by the unittest framework.

Answer 2

#test_numbers.py is located at 'tests' folder

import unittest 
class testNumbers(unittest.TestCase):

    def test_add_two_numbers(self):
    
        first_number = 3
        second_number = 7


        result = first_number + second_number 
        expected = 10


        self.assertEqual(result,expected)



if __name__ == '__main__':
    suite = unittest.TestLoader().loadTestsFromTestCase(testNumbers)
    unittest.TextTestRunner(verbosity=3).run(suite)

run on terminal :

python -m tests.test_numbers
