Overview of this book

NativeScript is an open source framework that is built by Progress in order to build truly native mobile apps with TypeScript, JavaScript or just Angular which is an open source framework built by Google that offers declarative templates, dependency injection, and fully featured modules to build rich applications. Angular’s versatile view handling architecture allows your views to be rendered as highly performant UI components native to iOS and Android mobile platforms. This decoupling of the view rendering layer in Angular combined with the power of native APIs with NativeScript have together created the powerful and exciting technology stack of NativeScript for Angular. This book focuses on the key concepts that you will need to know to build a NativeScript for Angular mobile app for iOS and Android. We’ll build a fun multitrack recording studio app, touching on powerful key concepts from both technologies that you may need to know when you start building an app of your own. The structure of the book takes the reader from a void to a deployed app on both the App Store and Google Play, serving as a reference guide and valuable tips/tricks handbook. By the end of this book, you’ll know majority of key concepts needed to build a successful NativeScript for Angular app.

Integration Testing with Appium


In this chapter, we discussed how to do unit tests and the pros and cons of two of the methods of doing unit tests. In a nutshell, Angular testing works for generic TypeScript code that does not call any NativeScript-specific code, and it runs your tests really quickly. The NativeScript testing harness runs inside your NativeScript application and has full access to anything you write and anything a normal NativeScript application can do. However, it requires the NativeScript application to be running to run its tests, so it might require a full build step before it can run your tests.

Now that we have discussed the two types of unit testing, hang on to your testing hat. In the next chapter, we will cover how to do end-to-end testing or full screen and application testing of your awesome application.
