gulpzilla-jest

This adds 2 gulp commands to gulpzilla:

1. gulp jest
2. gulp watch-jest

Install

$ npm install --save-dev gulpzilla-jest

Configuration

In gulpfile.js:

const gulp = gulpzilla({
  jest: {
    srcDir: __dirname + '__tests__' /* the test source code */
  }
});

Requirement

This plugin requires additional script defined: npm run jest

Simply add the script as shown below, in package.json:

{
  "scripts": {
    "jest": "jest" /* e.g. you can specify NODE_PATH or --[option] here */
  }
}

Jest Configuration

As jest-cli is a peerDependencies, jest configuration can be done following the usual ways in the official documentation inside package.json.

For example, in package.json:

{
  "jest": {
    "bail": true,
    "verbose": true,
    "scriptPreprocessor": "<rootDir>/node_modules/babel-jest",
    "testPathDirs": [
      "<rootDir>/__tests__"
    ]
  }
}
