Resolving the WebDriverException in Jenkins: ChromeDriver Not Found in PATH

When working with automation tools like the Robot Framework and Chrome WebDriver, running tests locally is often straightforward. However, issues can arise when attempting to execute the same tests through Jenkins, particularly when it comes to path configurations. One common problem developers face is the WebDriverException error message indicating that the 'chromedriver' executable needs to be in PATH. In this post, we will explore the reasons behind this error and provide a detailed solution to resolve it.

Understanding the Problem

You might have successfully set up the Robot framework to run with Chrome WebDriver locally, and everything works flawlessly. But once you move your tests to a Jenkins pipeline, the following error might pop up:

[[See Video to Reveal this Text or Code Snippet]]

This error signifies that Jenkins, which runs under a different user context (often as JENKINS_USER), cannot locate the ChromeDriver executable. In this case, even though you have confirmed its presence in the /usr/local/bin directory when you echo your PATH, Jenkins still cannot access it.

Why is Jenkins Unable to Find ChromeDriver?

The main reasons Jenkins cannot find the chromedriver executable are:

Different User Context: Jenkins usually runs as a system user that may not have the same environmental configurations as your local user, including custom path variables.

Environment Variables Configuration: The variable that allows executables to be found in the terminal may not be set correctly in Jenkins.

How to Make ChromeDriver Accessible to Jenkins

Here’s a step-by-step guide to configure Jenkins so that it recognizes the ChromeDriver executable in your environment.

Step 1: Access Jenkins Configuration

Open Jenkins: Launch your Jenkins instance through your web browser.

Manage Jenkins: Click on the "Manage Jenkins" option from the Jenkins home page.

Configure System: Find and select "Configure System" from the available options.

Step 2: Set Global Properties

Navigate to Global Properties: Scroll down to the "Global Properties" section in the configuration page.

Enable Environment Variables: Check the box next to "Environment Variables" to enable the configuration options.

Add ChromeDriver Path: Click on "Add" and input the following:

Name: PATH

Value: usr/local/bin:${PATH}

This configuration will ensure that the ChromeDriver located in /usr/local/bin is included in the PATH variable that Jenkins uses while executing jobs.

Step 3: Save the Configuration

After you have added the new environment variable:

Save Your Changes: Scroll down and click the “Save” button to apply the configuration changes.

Conclusion

By configuring the PATH variable in Jenkins to include the path of your ChromeDriver, you can fix the WebDriverException and allow Jenkins to successfully locate and execute the Chrome WebDriver. This solution ensures that your automated tests run seamlessly on both your local machine and Jenkins.

Now you can continue building reliable CI/CD pipelines while executing your tests without interruptions!
