wdio-safaridriver-service

WDIO SafariDriver Service

This service helps you to run the Safari browser seamlessly when running tests with the WDIO testrunner. It uses the /usr/bin/safaridriver that comes with Safari/OSX.

Note - this service does not require a Selenium server, but uses the /usr/bin/safaridriver to communicate with the browser directly. Obvisously, it only supports:

capabilities: [{
    browserName: 'safari'
}]

Installation

The easiest way is to keep wdio-safaridriver-service as a devDependency in your package.json.

{
  "devDependencies": {
    "wdio-safaridriver-service": "^1.0.0"
  }
}

You can simple do it by:

npm install wdio-safaridriver-service --save-dev

Instructions on how to install WebdriverIO can be found here.

Configure Safari to Enable WebDriver Support

Safari’s WebDriver support for developers is turned off by default. How you enable it depends on your operating system.

High Sierra and later

Run safaridriver --enable once. (If you’re upgrading from a previous macOS release, you may need to use sudo.)

Sierra and earlier

1. If you haven’t already done so, make the Develop menu available. Choose Safari > Preferences, and on the Advanced tab, select “Show Develop menu in menu bar.” For details, see Safari Help.

2. Choose Develop > Allow Remote Automation.

3. Authorize safaridriver to launch the XPC service that hosts the local web server. To permit this, manually run /usr/bin/safaridriver once and follow the authentication prompt.

Configuration

By design, only Safari is available, and will only work on Mac OS. In order to use the service you need to add safaridriver to your service array:

// wdio.conf.js
export.config = {
    // port to find safaridriver
    port: 4447, // if you want to specify the port. Default is 4444
    path: '/',
    // ...
    capabilities: [{
    /*
     * safaridriver can only handle 1 instance unfortunately
     * https://developer.apple.com/documentation/webkit/about_webdriver_for_safari
     */
    maxInstances: 1,
    }],
    services: [
        ['safaridriver', {
            outputDir: './logs',
            logFileName: 'wdio-safaridriver.log'
        }]
    ],
    // ...
};

Options

port

The port on which the driver should run on.

Array of arguments to pass to the safaridriver executable. -p will use wdioConfig.port if not specified.
