avatar Bite 246. Test print / standard output

Note this is a Test Bite and uses Python 3.7 and MutPy 0.6.1

In this Bite you test a function that prints to stdout. Check out pytest's Capturing of the stdout/stderr output how to test this.

You probably want to use the capsys / capfd fixture in your test code and you'll probably find a good use case for @pytest.mark.parametrize here too.

Have fun and keep calm and code in Python!
