Overview of this book

The React Native framework offers a range of powerful features that make it possible to efficiently build high-quality, easy-to-maintain frontend applications across multiple platforms such as iOS, Android, Linux, Mac OS X, Windows, and the web, helping you save both time and money. And this book is your key to unlocking its capabilities. Professional React Native provides the ultimate coverage of essential concepts, best practices, advanced processes, and tips for everyday developer problems. The book makes it easy to understand how React Native works under the hood using step-by-step explanations and practical examples so you can use this knowledge to develop highly performant apps. As you follow along, you'll learn the difference between React and React Native, navigate the React Native ecosystem, and revisit the basics of JavaScript and TypeScript needed to create a React Native application. What’s more, you’ll work with animations and even control your app with gestures. Finally, you'll be able to structure larger apps and improve developer efficiency through automated processes, testing, and continuous integration. By the end of this React native app development book, you'll have gained the confidence to build high-performance apps for multiple platforms, even on a bigger scale.

Understanding automated testing

There are different forms of automated testing. The following forms of automated testing are the most common ones and will be covered in this chapter:

  • Unit tests: Unit tests cover the smallest parts of your business logic, such as single functions.
  • Integration tests: This form of testing works very similar to unit tests in React Native, but it covers multiple pieces of your business logic and tests whether the integration of these parts works as expected.
  • Component tests: These tests cover your React Native UI components and check whether they do what they are expected to do. You can also check for (unexpected) changes in your components with this form of testing.
  • End-to-end tests: This form of testing simulates end user behavior and checks whether your whole application behaves like it is expected to do.

To get the most out of automated testing, you should implement all four types of tests. All of them cover different areas...
