Vue Testing Library


Simple and complete Vue.js testing utilities that encourage good testing practices.

Vue Testing Library is a lightweight adapter built on top of DOM Testing Library and @vue/test-utils.

Table of Contents


This module is distributed via npm and should be installed as one of your project's devDependencies:

npm install --save-dev @testing-library/vue

This library has peerDependencies listings for Vue 3 and vue-template-compiler.

You may also be interested in installing jest-dom so you can use the custom Jest matchers.

If you're using Vue 2, please install version 5 of the library:

npm install --save-dev @testing-library/vue@^5

A basic example

  <p>Times clicked: {{ count }}</p>
  <button @click="increment">increment</button>

  export default {
    name: 'Button',
    data: () => ({
      count: 0,
    methods: {
      increment() {
import {render, screen, fireEvent} from '@testing-library/vue'
import Button from './Button'

test('increments value on click', async () => {
  // The `render` method renders the component into the document.
  // It also binds to `screen` all the available queries to interact with
  // the component.

  // queryByText returns the first matching node for the provided text
  // or returns null.
  expect(screen.queryByText('Times clicked: 0')).toBeTruthy()

  // getByText returns the first matching node for the provided text
  // or throws an error.
  const button = screen.getByText('increment')

  // Click a couple of times.

  expect(screen.queryByText('Times clicked: 2')).toBeTruthy()

You might want to install jest-dom to add handy assertions such as .toBeInTheDocument(). In the example above, you could write expect(screen.queryByText('Times clicked: 0')).toBeInTheDocument().

Using byText queries it's not the only nor the best way to query for elements. Read Which query should I use? to discover alternatives. In the example above, getByRole('button', {name: 'increment'}) is possibly the best option to get the button element.

Guiding Principles

The more your tests resemble the way your software is used, the more confidence they can give you.

We try to only expose methods and utilities that encourage you to write tests that closely resemble how your Vue components are used.

Utilities are included in this project based on the following guiding principles:

  1. If it relates to rendering components, it deals with DOM nodes rather than component instances, nor should it encourage dealing with component instances.
  2. It should be generally useful for testing individual Vue components or full Vue applications.
  3. Utility implementations and APIs should be simple and flexible.

At the end of the day, what we want is for this library to be pretty light-weight, simple, and understandable.
