Python TDD Workflow - Unit Testing Code Example for Beginners

In this tutorial we will play the game of unit testing! 🎮🎮🎮
To do so - we will learn a brand new coding workflow, implementing a set of programming principles known as Test Driven Development.
I will introduce you to the Three Laws of TDD (also known as the Three Laws of Uncle Bob) and show how to write a piece of software unit by unit, test by test, 2 minutes at a time! ⏱️
The end result is not only a cool encryption algorithm known as Caesars Cipher - but also a series of unit tests that ensures its accuracy and reliability.
In the very end - I also have a 🏆 CHALLANGE 🏆 for you! So make sure you tune in at minute 23:10 to participate and practice your new set of skills! 💪
