Babel Setup

To write tests using next-generation JavaScript features, you can use Babel to compile your test files.

To do so, first install the necessary Babel dependencies:

npm install --save-dev @babel/core @babel/cli @babel/preset-env @babel/register

Make sure your babel.config.js is configured properly.

The simplest setup you can use is:

babel.config.js

module.exports = {
    presets: [
        ['@babel/preset-env', {
            targets: {
                node: 'lts'
            }
        }]
    ]
}

Once this is set up WebdriverIO will take care of the rest.
