unittest is the batteries-included test module in the Python standard library. Its API will be familiar to anyone who has used any of the JUnit/nUnit/CppUnit series of tools.

Creating test cases is accomplished by subclassing unittest.TestCase.

import unittest

def fun(x):
    return x + 1

class MyTest(unittest.TestCase):
    def test(self):
        self.assertEqual(fun(3), 4)

In this case, you would make a function like this:
In one file, hello_world.py, make this:

#!/usr/bin/env python3
def hello_world():
    return 'Hello, world!'

#Test: 
print ( hello_world() ) # If it prints Hello, world! then this program is working correctly.

If you feel strong and ambitious, try a more advanced test, perhaps.

In another file, test_hello_world.py, make a test like this:

import hello_world
import unittest # More details: https://docs.python.org/3/library/unittest.html

class TestHelloWorld(unittest.TestCase):
    def test_hello_world(self):
        self.assertEqual('Hello, world!', hello_world()) # For other programs, there are assertTrue() or assertFalse() to verify a condition; or assertRaises() to check an exception

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

// , Merge into Master branch.
