Open both name_normalizer.py and name_normalizer_test.py file in your favorite editor.

The normalize function's skeleton is placed at the top of name_normalizaer.py and needs to be implemented. The corresponding tests are placed in name_normalizer_test.py. The tests are disabled by the @unittest.skip attribute.

To enable a test, just delete the @unittest.skip attribute of the corresponding test. Now the enabled test will check your implementation when executed.

To run the tests, open up a terminal, cd into the Python project (this directory) and run python name_normalizer_test.

Now python will run all enabled tests and print the test results on your screen.
