Testing Vue.js Components with Jest

Learn how to unit test Vue.js components using Jest, a full-featured JavaScript testing framework. Shallow rendering, mocking dependencies, and more.

Unit testing in modern component-based JavaScript frameworks is not easy. Components are coupled together, and the browser adds a UI layer, making everything so dependent when we want to test components in isolation. We want the test suite to be robust and fast.

In this book, you will learn how to easily test Vue.js components and use the full-featured Jest testing framework along with the official Vue testing tool, Test Utils. This book will show you how to test the styles, structure, and behavior of your components in Vue.js. You will see how to use techniques like snapshots, shallow rendering, module dependency, and module aliases to make your tests more stable and clean.
