A quick look at the unittest module

Python comes with the built-in unittest module, which is a framework to write automated tests based on JUnit, a unit testing framework for Java. You create tests by subclassing from unittest.TestCase and defining methods that begin with test. Here's an example of a typical minimal test case using unittest:

    import unittest    from fibo import fibonacci    class Test(unittest.TestCase):        def test_fibo(self):            result = fibonacci(4)            self.assertEqual(result, 3)    if __name__ == '__main__':        unittest.main()

The focus of this example is on showcasing the test itself, not the code being tested, so we will be using a simple fibonacci function. The Fibonacci sequence is an infinite sequence of positive integers where the next ...
