Hello!

The code for this section is available here: https://github.com/tecladocode/complete-python-course/tree/master/course_contents/20_unit_testing

It's split into two folders: a code folder which contains the three major applications and sets of tests we'll write, and a lectures folder which contains lecture-by-lecture codes of everything we'll write.

Hope it's useful!
