jest-runner-mocha v0.6.0

jest-runner-mocha

An experimental Mocha runner for Jest

This makes it easy to integrate existing Mocha projects with Jest.

Usage

Install

Install jest(it needs Jest 21+) and jest-runner-mocha

yarn add --dev jest jest-runner-mocha

# or with NPM

npm install --save-dev jest jest-runner-mocha

Add it to your Jest config

In your package.json

{
  "jest": {
    "runner": "jest-runner-mocha"
  }
}

Or in jest.config.js

module.exports = {
  runner: 'jest-runner-mocha',
}

Run Jest

yarn jest

Options

This project uses cosmiconfig, so you can provide config via:

• a jest-runner-mocha property in your package.json
• a jest-runner-mocha.config.js JS file
• a .jest-runner-mocharc JSON file

In package.json

{
  "jest-runner-mocha": {
    "cliOptions": {
      // Options here
    },
    "coverageOptions": {
      // Options here
    }
  }
}

or in jest-runner-mocha.config.js

module.exports = {
  cliOptions: {
    // Options here
  },
  "coverageOptions": {
    // Options here
  }
}

cliOptions

jest-runner-mocha maps some mocha CLI arguments to config options. For example --ui is cliOptions.ui

coverageOptions

jest-runner-mocha has some optional configuration for code coverage

Coverage

Coverage works outside of the box, simply yarn jest -- --coverage

You can also use other Jest options like coveragePathIgnorePatterns and coverageReporters
