Getting Started with NativeScript

By: Nathanael J. Anderson

Overview of this book

NativeScript allows you to build a fast cross-platform application that has a native UI. NativeScript is a true cross-platform framework that generates native speed applications using the native components of the host platform, all using JavaScript. Although NativeScript allows you to build your application in JavaScript, you have full access to the host OS from your code, allowing you to easily tweak or use new platform features instantly at native code speeds. Whether you have already developed multiple applications or zero applications, this book will help you to develop your next application in a cross-platform framework quickly, saving you a massive amount of time and money. This book concisely shows you NativeScript’s built-in framework that allows you to rapidly develop a fully-working compiled cross-platform application in just a few chapters. It starts by laying the foundation of NativeScript and working through the fundamentals to create a basic shell of the application. Moving on, you’ll see how to build a full-fledged application step by step. We’ll show you how to use plugins, and how to communicate with the native OS libraries easily so that you can customize your application as if your app was created in Java or Objective C. We then deal with the issues that arise from being cross platform and compensate for the different screen sizes, screen resolutions, and device abilities. Finally, we progress to testing and deploying your app.

Chapter 7. Testing and Deploying Your App

Wow, we are almost done with learning NativeScript. The hard part is behind us. The fun part is about to begin. Testing and debugging! Just so I don't totally ruin your parade, we will discuss a couple of different ways to do testing outside of NativeScript. Then, we will explore how to read the call stack and how to debug your application. Finally, when your application is 100 percent bug free, we will see how to publish it.

In this chapter, we will cover the following topics:

  • Testing your application

  • Test frameworks

  • Local testing of your code

  • Unit testing on a device

  • Testing on a device

  • Understanding the call stack

  • Debugging your application

  • Publishing your application
