 * This is the default Jest configuration for Doodle frontends.
 * Note: changes to this file affect all projects that depend on it.
 *
 * How to use:
 * Create a jest.config.js file in your project and extend this configuration as
 * shown in the following example.
 * You can either extend the generated object, or pass the parameters specified
 * in the docs of `generateJestConfig`.
 *
 * @example
 * // File: web-my-frontend/jest.config.js
 * const { generateJestConfig } = require('@doodle/frontend-config/jest');
 * module.exports = generateJestConfig();
