  3. Extract the contents of the downloaded ZIP file to a location of your choice on your computer.

Downloading Selenium ChromeDriver for version 115.0 and above

After ChromeDriver version 114.0, the steps of installing were changed. Now, Google has launched Chrome For Testing Availability(CFTA) dashboard.


A version of Chrome will be installed, used explicitly for automation testing.

  1. Click on Stable and we will see a dashboard as shown below.
  2. specification

  3. Copy the URL according to your system specification, and the required version of Chrome and ChromeDriver gets installed.

This version of Chrome is used only for automation purposes and opens with this notification at the top.


Note: Only Selenium version 4.11.0 and above is compatible with Chrome browser version 115.0 and above. All the other steps remain the same.

Setting Up the ChromeDriver for Selenium

Let’s look at how to setup or configure the downloaded ChromeDriver for automation testing on Chrome with different systems.

Steps for Windows users

  1. Open File Explorer and navigate to the extracted ChromeDriver folder.
  2. Copy the path of the ChromeDriver executable file (ChromeDriver.exe).
  3. Open the “About” section in the settings
  4. Advanced

  5. In the System Properties window, click on “Advanced system settings“. A pop-up window appears.
  6. click

  7. Click on the “Environment Variables” button.
  8. Path

  9. Under the “System variables” section, locate the “Path” variable and select “Edit.”
  10. Click on “New” and paste the copied path of the ChromeDriver executable.
  11. Click “OK” to save the changes, and ChromeDriver is now installed on your Windows system.

Steps for Mac users

  1. Once the download is complete, open the downloaded ZIP file.
  2. In the Finder, press Command+Shift+G and enter “/usr/local/bin” to go to the bin directory.
  3. Copy the extracted ChromeDriver executable file (ChromeDriver) into the “/usr/local/bin” directory.

Steps for Linux users

  1. Extract the contents of the downloaded ChromeDriver ZIP file.
  2. You can use the ‘unzip‘ command followed by the name of the ZIP file. For example: unzip ChromeDriver_linux64.zip.
  3. Decide on a location where you want to store the ChromeDriver executable. It’s common to store it in the ‘/usr/local/bin’ directory, already in the system’s PATH.
  4. To move the ChromeDriver executable to ‘/usr/local/bin’, use the following command: sudo mv ChromeDriver /usr/local/bin.
  5. Once the ChromeDriver executable is moved, you need to make it executable. To grant executable permissions, run sudo chmod +x /usr/local/bin/ChromeDriver.

How to Check the Installed Version of Selenium ChromeDriver?

To check the installed version of Selenium ChromeDriver, one can follow these steps:

  1. Open a terminal or command prompt.
  2. Type the following command:
  3. The terminal will display the version number of the installed Selenium ChromeDriver.
  4. without

Alternatively, one can run the command chromeDriver without additional arguments. This will start ChromeDriver, and the output will display the version information.

This command only works when that chromedriver is installed explicitly in the environment variables path.

NOTE: While working with specific ChromeDriver versions for compatibility, you might encounter challenges during the maintenance phase. Updates to browsers and WebDriver versions can lead to mismatches that result in test failures. When a newer version of the browser, your existing test scripts might not function as expected due to version discrepancies. Manual download and setup as discussed above can be automated to make the lives of the testers or developers easy, which will be discussed later in this blog.

Steps to Run Automation Test With Selenium ChromeDriver

This section will show how to run the test scripts on one’s system. Here we have written a simple script in Python and Java, which will open an “e-commerce playground”. This is a demo website maintained by LambdaTest to run tests and learn the concepts. This script will print the title of the website. In our example, it will print “Your Store”.

Automating the Manual Process Of Managing Drivers

The pain of following the manual procedure. Selenium has used this concept to ship “Selenium Manager” out of the box as soon as you install the Selenium bindings. With Selenium Manager, you no longer have to worry about finding the right version, downloading it, setting it up, and maintaining it in the system path as it automates the steps involved.

We just need to write the following piece of code,

In Python:

driver = webdriver.Chrome()

In Java:

A Chrome’s driver object is instantiated, but this time, without having to download the driver binaries and mention a path as we saw in the manual procedure. This line of code works in a way such that it first identifies the current version of the browser, looks for a compatible driver in the environment, if found, uses it to instantiate the chrome driver object, otherwise, it downloads as per the version of chrome being used and manages it.

Steps to Run Automation Selenium Tests On LambdaTest Cloud Grid

To run your automation test on LambdaTest Cloud Grid, follow these steps:

1. Sign up for a LambdaTest account: Go to the LambdaTest website and sign up for an account if you still need to.

2. Retrieve your LambdaTest credentials: You can find these credentials in the “Automation” section of your LambdaTest account dashboard.

Note: access key information is present on the right hand side.

3. Update your test code to integrate with LambdaTest: To generate capabilities, go to capability generator. Select the code for which you want to generate and paste it. Here’s an example of how you can modify your code:

Make sure to replace the placeholders (Your Build Name, Your LambdaTest Username, Your LambdaTest Access Key) with the appropriate values from your LambdaTest account.

This code is a Python script using the pytest testing framework and the Selenium framework to automate browser testing on the LambdaTest cloud platform. The purpose of this script is to demonstrate how to set up and perform automated tests on a website using the Selenium WebDriver and interact with the LambdaTest Cloud Grid for testing on different browsers and platforms.

Here’s a step-by-step code walkthrough:

  • Import Statements:
  • The code starts with importing necessary libraries: pytest for testing and modules from Selenium for browser automation.

  • Fixture Definition (driver):
  • The @pytest.fixture decorator defines a fixture named driver. A fixture is a way to set up and tear down resources needed for testing.
    Inside the fixture, the desired capabilities for the LambdaTest Cloud Grid are defined using the lt_options dictionary. These capabilities specify the browser, version, platform, test name, build information, and other options for the test.

    Finally, a WebDriver instance is created using the webdriver.Remote class. The instance connects to the LambdaTest hub using the constructed remote URL and Chrome options.

  • Fixture Teardown:
  • A yield statement is used, which means that the code after yield will run after the test is done executing.

    In this case, the WebDriver instance is closed using driver.quit().

  • Test Scenario (test_scenario):
  • The actual test is defined as a function called test_scenario that takes the driver fixture as an argument.

    The test involves the following steps:

    • Opening a specific website using driver.get().
    • Getting the title of the webpage and asserting that it’s equal to “Your Store”.
    • Scrolling down the page using JavaScript (driver.execute_script()).
    • Performing a hover action over an element on the page using ActionChains.
    • Adding some wait time using time.sleep() to simulate interactions and visual checks.
    • The test is followed by a comment suggesting that more assertions or steps can be added based on the test scenario.
  • Main Execution:

The script’s main block is wrapped in an if __name__ == ‘__main__’: condition to ensure that its code is only executed when the script is run directly (not when imported as a module).
It invokes the pytest.main() function to run the test.

4. Run the test with LambdaTest integration: Execute the following command in the terminal to run your test code with the LambdaTest integration:

5. Review test results: Once the test run is complete, you can review the test results and logs on the LambdaTest dashboard. You’ll be able to see the screenshots, video recordings, and other details related to the test execution.

That’s it! Your automation test will now run on the LambdaTest Cloud Grid using the desired capabilities you specified.
