Welcome to your third unit of this course dedicated to practicing Test Driven Development (TDD) utilizing C++ and Google Test. We will begin building a new system; this time, we'll focus on creating a shopping cart module with a variety of features.

In this course, emphasis is placed on hands-on practice, where you'll receive requirements through tests, one at a time. Your task is to write tests and implement code that makes each test pass, simulating a real-world TDD environment. Unlike previous exercises, where tests were supplied, this time you're in charge!

Remember to utilize the core concepts of the Red-Green-Refactor cycle while working through these exercises. Assistance is available, so don't hesitate to ask for help.
