Jest Vue transformer with source map support

npm install --save-dev vue-jest

To define vue-jest as a transformer for your .vue files, you need to map .vue files to the vue-jest module.

"transform": {
  ".*\\.(vue)$": "<rootDir>/node_modules/vue-jest"
},

To use source maps, you need to set mapCoverage to true. A full config will look like this.

{
  "jest": {
    "moduleFileExtensions": [
      "js",
      "json",
      "vue"
    ],
    "transform": {
      "^.+\\.js$": "<rootDir>/node_modules/babel-jest",
      ".*\\.(vue)$": "<rootDir>/node_modules/vue-jest"
    },
    "mapCoverage": true
  }
}

Example repositories testing Vue components with jest and vue-jest:

• Avoriaz with Jest
• Vue Test Utils with Jest

vue-jest compiles the script and template of SFCs into a JavaScript file that Jest can run. It does not currently compile the style section.

• typescript (lang="ts", lang="typescript")
• coffeescript (lang="coffee", lang="coffeescript")

• pug (lang="pug")
• jade (lang="jade")
• haml (lang="haml")
