Automating Cef Based Applications with Selenium: A Step-by-Step Guide

Automating applications developed with the Chromium Embedded Framework (CEF) can be challenging, especially when interoperability with Selenium WebDriver is required. Many developers face issues while attempting to control CEF applications using Selenium. If you’re one of those facing this challenge, you’ve come to the right place. In this guide, we’ll explore how to set up Selenium to automate a CEF-based application effectively and provide solutions to common hurdles.

The Problem at Hand

When trying to automate a CEF application using Selenium, you might encounter difficulties related to the application launch sequence, especially when passing URLs as arguments. As per the previously mentioned requirements:

You need to create a shortcut or use the command prompt to launch the application while passing the URL.

Setting up Selenium with the right options can sometimes lead to errors, particularly when you attempt to integrate the application’s binary executable and the desired URL.

Key Issues Faced:

The webdriver correctly identifies the application binary.

Trouble with the URL passing when using options.addArguments().

The Solution Explored

In this section, we will break down the solution to the aforementioned issue that highlights how to effectively automate CEF applications with Selenium by ensuring proper setup and utilizing debugging features.

Step 1: Check the Development Code

The first step in solving the problem often lies in collaborating with your development team:

Ask the Developers: Request them to attach a remote debugging port (such as --remote-debugging-port=9222) when initializing the browser via the executable. This is essential for effective communication between Selenium and the CEF application.

Step 2: Setting Up ChromeOptions

Once you have the remote debugging port configured, you can utilize Selenium's ChromeOptions for setting up the necessary parameters. Here’s how you can effectively initialize your WebDriver:

Step 3: Utilize Experimental Options

Another important aspect is to control an already running instance of the Chrome browser:

Additional Troubleshooting Tips

If you still face issues, double-check your binary path.

Ensure that the CEF application is not blocking any external connections.

Testing in isolation can help identify if the error is within the application code or the automation setup.

Conclusion

Automating CEF-based applications with Selenium may seem daunting due to particular requirements and setup challenges. However, with the right approach—such as verifying your development settings, using ChromeOptions, and utilizing a debugging port—you can overcome these hurdles effectively. Collaboration with your development team can also lead to a more streamlined process, ensuring that you can control your automation tasks effortlessly.

By following this guide, you should be well-equipped to handle CEF application automation using Selenium WebDriver. Happy testing!
