npm i cypress -D

Open Cypress:

npx cypress open

Choose Component Testing

The Cypress Launchpad will guide you through configuring your project.

For a step-by-step guide on how to create a component test, refer to the Vue Quickstart guide.

For usage and examples, visit the Vue Examples guide.

Framework Configuration

Cypress Component Testing works out of the box with Vue CLI, Nuxt, Vite, and a custom Webpack config. Cypress will automatically detect one of these frameworks during setup and configure them properly. The examples below are for reference purposes.

Vue CLI

Cypress Component Testing works with Vue CLI.

Vue CLI Configuration

cypress.config.js

const { defineConfig } = require('cypress')

module.exports = defineConfig({
  component: {
    devServer: {
      framework: 'vue-cli',
      bundler: 'webpack',
    },
  },
})

cypress.config.ts

import { defineConfig } from 'cypress'

export default defineConfig({
  component: {
    devServer: {
      framework: 'vue-cli',
      bundler: 'webpack',
    },
  },
})

caution

PWA Caveat

If you use the Vue CLI's PWA feature, there is a known caveat regarding configuration. See here for more information.

Sample Vue CLI Apps

• Vue 3 CLI 5 with TypeScript
• Vue 2 CLI 4 with JavaScript

Nuxt

Cypress Component Testing works with Nuxt 2. Nuxt 3 is not yet supported.

caution

Nuxt is currently in alpha support for component testing.

Nuxt Configuration

cypress.config.js

const { defineConfig } = require('cypress')

module.exports = defineConfig({
  component: {
    devServer: {
      framework: 'nuxt',
      bundler: 'webpack',
    },
  },
})

cypress.config.ts

import { defineConfig } from 'cypress'

export default defineConfig({
  component: {
    devServer: {
      framework: 'nuxt',
      bundler: 'webpack',
    },
  },
})

Nuxt Sample Apps

• Vue 2 Nuxt 2 with JavaScript

Vue with Vite

Cypress Component Testing works with Vue apps that use Vite 2+ as the bundler.

Vite Configuration

cypress.config.js

const { defineConfig } = require('cypress')

module.exports = defineConfig({
  component: {
    devServer: {
      framework: 'vue',
      bundler: 'vite',
    },
  },
})

cypress.config.ts

import { defineConfig } from 'cypress'

export default defineConfig({
  component: {
    devServer: {
      framework: 'vue',
      bundler: 'vite',
    },
  },
})

Vue Vite Sample Apps

• Vue 3 Vite with TypeScript

Vue with Webpack

Cypress Component Testing works with Vue apps that use Webpack 4+ as the bundler.

Webpack Configuration

cypress.config.js

const { defineConfig } = require('cypress')
const webpackConfig = require('./webpack.config')

module.exports = defineConfig({
  component: {
    devServer: {
      framework: 'vue',
      bundler: 'webpack',
      // optionally pass in webpack config
      webpackConfig,
      webpackConfig: async () => {
        // ... do things ...
        const modifiedConfig = await injectCustomConfig(baseConfig)
        return modifiedConfig
      },
    },
  },
})

cypress.config.ts

import { defineConfig } from 'cypress'
import webpackConfig from './webpack.config'

export default defineConfig({
  component: {
    devServer: {
      framework: 'vue',
      bundler: 'webpack',
      // optionally pass in webpack config
      webpackConfig,
      webpackConfig: async () => {
        // ... do things ...
        const modifiedConfig = await injectCustomConfig(baseConfig)
        return modifiedConfig
      },
    },
  },
})

If you don't provide one, Cypress will try to infer your webpack config. If Cypress cannot or you want to make modifications to your config, you can pass it in manually via the webpackConfig option.

Vue Webpack Sample Apps
