var downloadfile = path.join(__dirname,'\\dash-e2e-tests\\resources\\files-cabin\\download-files');

capabilities: {
    browserName: 'chrome',
    'chromeOptions': {
        prefs: {
            download: {
                'prompt_for_download': false,
                'directory_upgrade': true,
                'default_directory': downloadfile
            }
        }
    }

},
