Test-Driven iOS Development with Swift

By: Dr. Dominik Hauser

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.

Chapter 6. Putting It All Together

In previous chapters, we implemented the different parts of our app using TDD. Now, it is time to put all the the parts together to develop a complete app.

This part of the implementation using TDD is the most exciting one. Usually, when not using TDD, you build and run the app in the simulator all the time to check whether your code works and changes bring the app closer to its final state.

In TDD, most of the development is done without running the app on the simulator or device. The tests guide the implementation. This has one big advantage: you can implement parts of the app that need to talk to a component that has not been implemented yet. For example, you can write and verify the complete data model before a View Controller or view is able to bring the data on the screen.

In this chapter, we will put the different parts of our code together to form the final app. In addition to this, we will take a look at how functional tests can help to find bugs...
