DRAFT
A series of exercises to illustrate testing. This workshop will take you on a journey to improve a small application that was built without testing in mind. Each exercise is in its own branch and is called a chapter. The README.md file in each chapter contains a situation description and a mission for you to do, should you choose to accept it. Successive chapters contain a solution to the previous chapter. This is not a test and there are no right answers. For now, we are just covering the basics of testing and refactoring.
