Test-Driven iOS Development with Swift 3

Overview of this book

<p>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 apps. In combination with the improved syntax of Swift 3, there is no excuse or writing bad code.</p> <p>This book will help you understand the process of TDD and how it impacts your apps written in Swift. Through a practical, real-world example app, you’ll start seeing how to implement TDD in context. You will begin with an overview of the TDD workflow and then deep dive into unit testing concepts and code cycles. You will also plan and structure your test driven iOS app, and write tests to drive the development of the view controllers and the helper classes. Next, you’ll learn how to write tests for network code, what CI is and how to set it up using Xcode Server.</p> <p>Finally, the book will guide you through the next steps to become a testing expert by discussing integration tests, Behavior Driven Development (BDD), open source testing frameworks and UI Tests introduced in Xcode 8.</p>

The task list view


When starting the app, the user sees a list of to-do items. The items in the list consist of a title, an optional location, and the due date. New items can be added to the list by an add (+) button, which is shown in the navigation bar of the view. The task list view will look like this:

User stories:

  • As a user, I want to see the list of to-do items when I open the app

  • As a user, I want to add to-do items to the list

In a to-do list app, the user will obviously need to be able to check items when they are finished. The checked items are shown below the unchecked items, and it is possible to uncheck them again. The app uses the delete button in the UI of UITableView to check and uncheck items. Checked items will be put at the end of the list in a section with the Finished header. The user can also delete all the items from the list by tapping the trash button. The UI for the to-do item list will look like this:
