Test Driven Development with Unit Tests in Xcode (XCTest) - Swift TDD Code Kata (3/4)
Part 3/4: Learn how to write Swift code with Test Driven Development (TDD). This 4 part series is based on my guest lecture that I gave for Lambda School students in the iOS Development track.

In this lesson you'll see how to refactor your unit tests to remove duplicated logic. You want to use the DRY principle in your code and your tests: Don't Repeat Yourself.
You'll learn how to write code using a TimeTraveler based on John Sundell's article on unit testing time (Link below).
By following along and writing the code, you can turn this exercise into a Code Kata, which you can practice over again to reinforce the concepts for testing time related code.
The code uses dependency injection to provide a new date generating function, so that we can time travel in your unit tests. Unit testing is a great way to verify the logic works like you expect it to work.
