Learning Python Application Development

Writing unit tests for the application

It is time to write some unit tests for the application. We will make a new subclass of unittest.TestCase to hold all the unit tests.

Setting up a test package

As a first step, let's create a new package for holding the test cases. Create a new directory called test at the same level where you have the rest of the code. Next, create two new files inside this test directory, as shown here:

The test_wargame.py module is where new unit tests will be created. To recognize the directory as a Python package, add an empty __init__.py file.
