Being able to test your application is crucial for smooth development workflow. You want to release features with as few bugs as possible, so it's important to write unit tests to test both your logic and rendering part. Usually, setting and configuring the testing framework properly is a nontrivial task; however, with React Native, we have a built-in testing mechanism. After you create your first app by running the following command: react-native init myFirstApp, you already have tests configured as well as several basic unit tests which reside in the __tests__ folder. By running npm test, you can run tests using the Jest framework from Facebook.

Overview of this book
<p>The emergence of React Native has made creating mobile apps in JavaScript easier for developers. This book introduces you to the React Native framework and the mobile apps development process. It starts with how React Native fits into the world of hybrid apps, and why it’s a popular framework. You’ll learn how React Native works under the hood--compiling JavaScript to Native code to bridge JavaScript and native apps. Also, you’ll learn how to write React Native components and use the ReactJS way of structuring your app. Understand how to use the industry standard Redux architecture as well as MobX--a newly emerging approach for state management--making your apps more robust and scalable.</p>
<p>The mobile native world can be intimidating, with lots of platform-specific APIs. In this book, you’ll learn about the most important APIs with help of the real-world examples. You’ll also learn about the community packages that can help speed up your development. The book explains how to use these packages with JavaScript code, include native modules in your application, and write the modules yourself. Throughout the book, you will see examples of WhatsApp, Instagram, and YouTube apps and learn how to recreate them. You’ll also learn debugging and testing techniques, authentication, dealing with real data, and much more.</p>
<p>At the end we will walk through design to production process of Twitter app clone and will explain application release process to App Store and Play Store</p>
