How to Run Parallel Tests with Remote Browser in TestCafe

Are you looking to optimize your testing process by executing parallel tests with TestCafe on a remote browser? Running tests concurrently can save you time and effort, especially as your pipeline scales. In this guide, we will guide you through the process of configuring TestCafe to run parallel tests on a remote browser, ensuring that you get the most out of your testing setup.

Understanding the Problem

You may have already set up your TestCafe tests to run concurrently in a local environment using a command like this:

This command opens two instances of the Chrome browser, executing your tests in parallel as expected. However, when you attempt to run tests on a remote browser using the command:

You encounter a limitation where you only receive a single connection URL, preventing simultaneous connections and, ultimately, causing tests not to start at their intended pace.

The Solution: Configuring Remote Browser Testing

Step 1: Understanding Connection URLs

When you run the command with the remote:2 argument, TestCafe will output a URL that you need to navigate to in each of the remote browser instances you intend to use. This is essential for establishing connections with those browsers.

Step 2: Connecting Multiple Browsers

To run your tests in parallel effectively, you will need to follow these connection steps:

Open the Connection URL: Start by opening the connection URL provided by TestCafe (e.g., http://192.168.1.1:64828/browser/connect) in the first remote browser window.

Connect the Second Browser: Repeat the process in a second remote browser window by navigating to the same URL.

Wait for Connection Confirmation: Ensure that both browsers display a CONNECTED message. This indicates that both instances are properly connected before your tests commence.

Example Workflow

Here’s a quick summary of what your workflow should look like:

Run the command:

Open your first remote browser and enter the connection URL.

Open your second remote browser and enter the same URL.

Monitor the console for both browsers to show the CONNECTED status.

Troubleshooting Tips

If you find that tests are still not starting as expected, consider these troubleshooting steps:

Ensure both remote browsers are active and correctly navigating to the provided URL.

Check firewall or network settings that may be blocking the connection.

Verify that your TestCafe version and configuration are up-to-date and correctly set for remote testing.

Conclusion

By following the steps outlined above, you can efficiently run your TestCafe tests in parallel on remote browsers. This setup not only enhances your testing speed but also provides the flexibility needed for larger testing pipelines. Don't hesitate to tweak your configuration as necessary to suit your needs, and always consider the environment in which you're running your tests.

Now, get ready to accelerate your testing phase and watch your productivity soar with parallel testing in TestCafe!
