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 yourpackage.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
|option|example
|-----|-----|
|ui|"ui": "tdd"
|timeout|"timeout": 10000
|compiler|"compiler": "./path/to/babel-register"
|file|"file": ["./path/to/include.js", "/supports/multiple/files.js"
]
coverageOptions
jest-runner-mocha has some optional configuration for code coverage
|option|example|description|
|-----|-----|-----|
|useBabelRc|"useBabelRc": true
|read .babelrc when instrumenting for code coverage (required if you transpile your code with babel).|
Coverage
Coverage works outside of the box, simply yarn jest -- --coverage
You can also use other Jest options like coveragePathIgnorePatterns and coverageReporters
