yarn add jest enzyme enzyme-adapter-react-16 --dev

Overriding default Encore configuration Webpack Encore fills in webpack.config.js file with initial instructions to configure the asset system. We need to modify the file slightly, cause Jest & Enzyme require instructions from babel.config.js to load js modules. To do so, remove or just comment the lines below:

Webpack Encore amendment inside webpack.config.js

    // enables @babel/preset-env polyfills
    // .configureBabelPresetEnv((config) => {
    //     config.useBuiltIns = 'usage';
    //     config.corejs = 3;
    // })
