Jest Vue transformer with source map support

Usage

npm install --save-dev jest-vue

Setup

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

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

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/jest-vue"
    },
    "mapCoverage": true
  }
}
