jest-runner-mocha

Mocha runner for Jest

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

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 

In your package.json

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

Or in jest.config.js

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

yarn jest

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 } }

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

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

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

You can also use other Jest options like coveragePathIgnorePatterns and coverageReporters
