Run WD Tests in Parallel

Run multiple WD tests in parallel on BrowserStack Automate

On BrowserStack, you can run multiple WD tests at the same time across various browser, device and OS combinations. This is called Parallel Testing. Parallel Testing gives you the same benefits as running a multi-threaded application.

With Parallel Testing, you can run the same test on different browser/device combinations i.e. cross-browser testing, or run different tests on the same or different browser/device combinations. Parallel Testing will help you reduce the run time of your test suite, resulting in faster build times and faster releases.

Run sample test in parallel

1. Clone the wd-browserstack sample repo on GitHub, if not already done:
   
   

   git clone https://github.com/browserstack/wd-browserstack.git
   cd wd-browserstack
   

2. Install the dependencies using npm install

3. Setup your credentials and browser/devices where you want to run your test, in the wd-browserstack/conf/parallel.conf.js file as shown below:
   
   

   parallel.conf.js

    exports.config = {
      user: 'YOUR_USERNAME',
      key: 'YOUR_ACCESS_KEY',
   
      seleniumHost: 'hub-cloud.browserstack.com',
      seleniumPort: 80,
   
      commonCapabilities: [{
        "browserstack.debug": true
      }],
   
      "capabilities": [{
        "browser": "chrome"
      },{
        "browser": "firefox"
      },{
        "browser": "safari"
      },{
        "browser": "internet explorer"
      }]
    }
   

4. You can now run your tests in parallel on BrowserStack using the following command:

    npm run parallel
   

5. You can also run you test in other environments by specifying that in the capabilities variable as shown below:

   "capabilities": [{
        "browser": "chrome",
        "browser_version": "latest",
        "os": "Windows",
        "os_version": "10"
      },{
        "device": "iPhone 12 Pro",
        "browser": "iPhone",
        "os_version": "14"
      },{
        "browser": "safari",
        "browser_version": "latest",
        "os": "OS X",
        "os_version": "Big Sur"
      },{
        "device": "Samsung Galaxy S20 Ultra",
        "browser": "Android",
        "os_version": "10.0"
      }]
