@digest/jest provides a Jest configuration that works with Babel, and optionally React and Typescript. To use the provided Jest configuration, simply include the following scripts in your package.json:

	"scripts": {
		"test": "jest --config node_modules/@digest/jest/dist/jest.config.js --no-cache --coverage",
		"test:dev": "jest --config node_modules/@digest/jest/dist/jest.config.js --no-cache --watch"

If you are using react or typescript, don't forget to include the @digest/jest-react or @digest/jest-typescript packages.
The following optional properties are provided for additional configuration in your digest.config.json or environment variables:
| digest.config.js | Environment Variable | Description | Default | Options | |---------------------------|---------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------|---------------------------------------| | n/a | DIGEST | Path to Webpack Digest settings. It contains these settings. | /webpack.digest.config.js | | | config | CONFIG | Path to Webpack config. | /webpack.config.js or default config from Webpack Digest | | | reportPath | REPORTPATH | Path to generate reports | /reports | | | testConfig | TESTCONFIG | Path to optional script that is picked up by the provided Jest config to setup additional test suites such as enzyme | /testconfig.js | | | tsconfig | TSCONFIG | Path to TypeScript config | /tsconfig.json or defaults packaged with Webpack Digest | |
The TESTCONFIG option is for additional test suite configuration when using the provided Jest config. By default it will look for a testconfig.js file in the root of the project. This file is run via Jest's setupFiles
option. This is required when using some libraries like enzyme. For example:

import {configure} from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';

configure({adapter: new Adapter()});

// For async tests, catch all errors here so we don't have to try / catch
// everywhere for safety
process.on('unhandledRejection', (error) => {

Remember, this file is not provided by default since it can be quite unique to each project.
