Troubleshooting Selenium: Fixing Edge WebDriver Exception

If you've been working with Selenium and suddenly found your tests failing with the following error message:

You are not alone! Many developers encounter this issue, especially when there is a mismatch between the version of the browser and the WebDriver. In this guide, we'll dive deep into understanding this problem and how to fix it effectively.

Understanding the Problem

When you run Selenium tests, the WebDriver is responsible for controlling the web browser. If the WebDriver version does not match the version of the installed browser (in this case, Microsoft Edge), you will encounter errors like the one described above. Here, your Edge WebDriver only supports version 106, while your actual browser version is 108.

Initial Thoughts

You may assume that having the latest version of the Edge WebDriver would resolve the issue. It may lead to confusion, especially if the correct version is already present in your PATH environment variable.

The Solution: Step-by-Step Guide

Here’s how you can troubleshoot and resolve the version mismatch issue:

1. Search for Redundant Edge Drivers

Sometimes, old versions of the WebDriver can cause conflicts. Follow these steps:

Open your file explorer.

Search for keywords like "msedgedriver" or "MicrosoftWebDriver".

It’s usually more effective to use "MicrosoftWebDriver" for locating the appropriate files.

2. Delete Old Versions

Make sure to pay attention to the versions of the Edge WebDriver you find:

Remove any instances of the WebDriver that are not the correct version, particularly any that reference version 106.

3. Rename the WebDriver (If Necessary)

If you encounter another error that states:

You might need to rename your WebDriver. Here’s what to do:

Change the driver name from msedgedriver to MicrosoftWebDriver.

Java Selenium may prefer this naming convention, which could fix the issue.

4. Set the Driver Location Explicitly

If the problem persists, you can set the driver location directly in your code:

This method bypasses the PATH variable and directs your test to the explicit WebDriver location.

Conclusion

With these steps, you should be able to overcome the Selenium exception related to the Edge WebDriver version mismatch. Always ensure that your browser and WebDriver are aligned to avoid unexpected interruptions in your automation tasks. Happy testing!
