Examples of Vue.js Component Unit Testing

This repository contains code examples written for the series of articles “Unit Testing Vue.js Components with the Official Vue Testing Tools and Jest” by Alex Jover.

Getting started

We assume you're already familiar with Vue.js framework and a concept of unit testing.

You might also want to have a look at the testing tools that we're going to use in this series: vue-test-utils (an official test library for Vue.js) and Jest (testing framework developed by Facebook).

Preparing and running tests

To run the code from this repository and build the application use the following commands in your terminal:

# clone the repository
git clone git@github.com:alexjoverm/vue-testing-series.git

# change the folder
cd vue-testing-series

# install dependencies
npm install

# serve with hot reload at localhost:8080
npm run dev

# run tests once
npm t

# run tests in watch mode to monitor what breaks as you change the code
npm t -- --watch

Build Setup

# build for production with minification
npm run build

# build for production and view the bundle analyzer report
npm run build --report

For the detailed explanation of how things work, check out the Vue.js Templates guide and docs for vue-loader.
