By: Solomon Eseme

Overview of this book

Building enterprise-ready Vue.js apps entails following best practices for creating high-performance and scalable applications. Complete with step-by-step explanations and best practices outlined, this Vue.js book is a must-read for any developer who works with a large Vue.js codebase where performance and scalability are indispensable. Throughout this book, you’ll learn how to configure and set up Vue.js 3 and the composition API and use it to build real-world applications. You’ll develop the skills to create reusable components and scale performance in Vue.js 3 applications. As you progress, the book guides you in scaling performance with asynchronous lazy loading, image compression, code splitting, and tree shaking. Furthermore, you’ll see how to use the Restful API, Docker, GraphQL, and different types of testing to ensure that your Vue.js 3 application is scalable and maintainable. By the end of this book, you’ll be well-versed in best practices for implementing Restful API, Docker, GraphQL, and testing methods to build and deploy an enterprise-ready Vue.js 3 application of any scale.

Component testing in Vue.js 3

In Vue.js, components are the main building block of the UI and refer to a single unit of the application that is shareable, testable, and reusable. Therefore, component testing sits between unit testing and end-to-end testing. It can also be referred to as integration testing.

In the previous chapters, where we integrated atomic patterns using Storybook, we discussed creating component stories and how to create them. If you created stories for all your components and configured them to work properly as demonstrated, then you will have already implemented component testing using Storybook stories.

However, Chapter 10, Integrating Testing in Vue.js 3 is dedicated to exploring component testing. Nevertheless, we will briefly illustrate in this chapter how to implement simple component-based testing to aid our understanding of the next chapters.

Writing a basic component test

We will start by installing the new testing library for Vue.js 3. Since...
