Test-Driven iOS Development with Swift

Overview of this book

Test-driven development (TDD) is a proven way to find software bugs early. Writing tests before your code improves the structure and maintainability of your app. Test-Driven iOS Development with Swift will help you understand the process of TDD and how it impacts your applications written in Swift. Through practical, real-world examples, you’ll start seeing how to implement TDD in context. We will begin with an overview of your TDD workflow and then deep-dive into unit testing concepts and code cycles. We will showcase the workings of functional tests, which will help you improve the user interface. Finally, you will learn about automating deployments and continuous integration to run an environment.

Summary


In this chapter, we took a look at how to implement the model layer of our app using TDD. We followed the TDD workflow (red, green, and refactor) to guide the implementation of the required micro features.

We implemented two model structs and a manager class. We added conformance to the Equatable protocol for the model structs in order to make sure that the same to-do item cannot be added to the list more than once. We also encapsulated the internals of the manager class with methods to add, receive, and remove to-do items from the manager.

TDD lead us to a clean, simple, and fully tested model.

In the next chapter, we will implement the controller layer and the view layer of the Model-View-Controller design pattern using TDD.
