Module 4 (April 15026)

In this module, we will focus on testing our code.

Testing Your Code

Read the following articles from The Hitchhiker's Guide to Python:

1. Structuring Your Project
2. Testing Your Code
3. Examples for using pytest

Some Testing Examples

 
    import unittest

    class TestStringMethods(unittest.TestCase):

        def test_upper(self):
            self.assertEqual('foo'.upper(), 'FOO')  # Edit FOO to see fail output

        def test_isupper(self):
            self.assertTrue('FOO'.isupper())
            self.assertFalse('Foo'.isupper())

        def test_split(self):
            s = 'hello world'
            self.assertEqual(s.split(), ['hello', 'world'])
            # check that s.split fails when the separator is not a string
            with self.assertRaises(TypeError):
                s.split(2)

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

 
    def inc(x):
        return x + 1

    def test_answer():
        assert inc(3) == 5 #Fails, since inc(3) is 4, not 5
    

 
    def square(x):
        """Return the square of x.

        >>> square(2)
        4
        >>> square(-2)
        4
        """

        return x * x

    if __name__ == '__main__':
        import doctest
        doctest.testmod() # Expect no output if everything passes
    

Creating Test Suites

Sample exercises from CSC108:

1. Is Teenager
2. All Fluffy
