Improve current or new projects with top notch testability and maintainability. Writing tests
improves the design of your apps as it pushes you to have a more modularized design. This in
turn improves the maintainability and sustainability of your apps. This book is for iOS
developers who already know the basics of iOS and Swift development but want to learn all the
testing pro features in iOS. You'll start by reviewing the TDD Cycle and how to implement these
concepts on a legacy project or a new one. You'll then walk through TDD step-by-step on a blank
project including setting up test targets assertions and expectations. You'll follow that
with all levels of testing such as unit tests integration tests and end-to-end tests and
also tackle fairly complex yet badly written legacy code. The book will take you through the
journey of modularizing a legacy app using TDD. Throughout this journey you will be introduced
to multiple testingconcepts and techniques like writing tests for network and core data
layers. You will write tests to ensure the thread safety of your app. And you'll add a new
feature while you are in the middle of refactoring which is an important skill so you can keep
adding features while you are fixing your technical debt. By the end of this book you will
have all the tools needed to become a testing master. What You'll Learn Use mocking and
dependency injection to make components more testable Write tests for asynchronous code like
network code Add new features to existing legacy apps using TDD Who This Book Is ForExperienced
iOS developers who care about software quality and meeting customer expectations.
