/**
 * A basic Nightwatch custom command
 *  which demonstrates usage of ES6 async/await instead of using callbacks.
 *  The command name is the filename and the exported "command" function is the command.
 *
 * Example usage:
 *   browser.openHomepage();
 *
 * For more information on writing custom commands see:
 *   https://nightwatchjs.org/guide/extending-nightwatch/#writing-custom-commands
