According to netmarketshare, Google Chrome accounts for 67% of the browser market share. It is the choice of the majority of users and it’s popularity continues to rise. This is why, as an automation tester, it is important that you perform automated browser testing on Chrome browser.

ChromeDriver is used along with Selenium to automate tests on the Chrome browser. Using Selenium ChromeDriver, you can communicate with Chrome browser to perform different operations like navigation from one web page to another web page, users can provide input on the web pages, javascript execution and many more operations.

In this article, I will show you how to use Chrome Driver to perform Selenium test automation. I’ll go into details about the ChromeDriver, starting from download, installation and to use it on Windows and Mac.

If you’re new to Selenium and wondering what it is then we recommend checking out our guide – What is Selenium?

What Is ChromeDriver In Selenium?

To perform automated browser testing on Chrome browser, ChromeDriver class, a standalone executable, is used by Selenium WebDriver to create communication of our test script with the Chrome browsers. You can create a WebDriver object for Chrome like below:

Selenium WebDriver helps our test script capabilities or power to communicate with the browser. ChromeDriver class extends WebDriver interface. It is an implementation of WebDriver interface which is used to control the Chrome browser running and operations on the local machine.

With the help of Selenium ChromeDriver class, we can easily interact with Chrome browser and perform automation testing of web applications on chrome browser.

This is implementation for Selenium ChromeDriver class

What Are The Requirements For Selenium ChromeDriver?

Before starting to explore Selenium ChromeDriver, there are few prerequisites which should be available on your system.

  1. Java/ JDK/JRE: In this guide, I’ll perform automation testing in Selenium with Java, so in order to run the tests I’d need to have Java/JDK/JRE installed in my system.

    You can download and install it from the official website for Java.

    I have used Java 8, JRE-1.8 for the Selenium test automation script execution.

  2. Eclipse IDE: To write a test automation script with selenium, you’d require an editor. In this case, I have used eclipse IDE. It can be downloaded from the official website of Eclipse.

    You can use the same editor or you can use other editors as well.

  3. Selenium: To write selenium automation test scripts, you’d require Selenium to be installed in your system. You can download it from the official website of selenium.

    In this article I have used selenium version 3.141.59, which is the latest stable version of selenium.

  4. Chrome Browser: Since we’d be performing Selenium test automation on chrome browser, it is required that our system should have chrome browser installed. It can be downloaded from

    I have used google chrome Version 78.0.3904.108 for the Selenium automation script.

How Do I Download Selenium ChromeDriver?

Step 1: To download Selenium ChromeDriver, go to the official website of Selenium.

download chromeDriver in Selenium

Step 2: Now click on the Downloads tab on the top right side of the home page. So that we will get redirected to the download page.


Step 3: On the Downloads page, scroll down to the Browsers section as shown in below image.


Step 4: Expand Browsers section, here you can see links for different browsers. For Chrome browser, click on ‘Documentation’ link under the ‘Chrome’ section.

Downloading ChromeDriver in Selenium

Step 5: Once you click on the documentation for Chrome browser from chrome section, we will be redirected to the page ( from where you can download zip file for Automation testing with ChromeDriver.

chromedriver in Selenium

In the above screenshot, you can see two options for Chrome Driver download. As ChromeDriver 78.0.3904.105 is the latest stable version available for the download, you should download that for better results..

While downloading the Chrome Driver, you need to make sure that it is compatible with the chrome browser version you’re using. Like Chrome Driver which I have downloaded, version 78.0.3904.105 will support all versions of Chrome browsers which start with 78.0.3904.

Step 6: Once you click on the latest stable version, it will open the following page which gives us an option to select the Chrome Driver to download for different operating systems like Linux, Mac and Windows.


Step 7: Download Selenium ChromeDriver for your operating system. For running tests on the Windows operating system, you can download ChromeDriver for Windows , just click on it and it will download the zip file of the Chrome Driver.

Once that zip file of ChromeDriver for Windows is downloaded, you can extract the ChromeDriver.exe file from that zip file.

Similarly, ChromeDriver for macOS can be downloaded. To install ChromeDriver on the macOS, we need to download it from the official website, we need to click and download file.


How To Use Selenium ChromeDriver On Windows?

Now that I have downloaded ChromeDriver and have installed other prerequisites applications as well in the system, I’ll use Chrome Driver and perform Selenium test automation scripts for the login test case on LambdaTest website.

For Windows, there are two different methods for Selenium test automation with Chrome Driver.

a) By using setProperty()

Using the setProperty() method from system class, I’ll provide the path of Chrome Driver from where the Selenium WebDriver can access it for Selenium test automation.

You can see the syntax for, how to set the location for the ChromeDriver.exe below:

So, let’s take a test scenario, login on LambdaTest platform using setProperty().

Steps for Test case:

  • Open the chrome browser
  • Navigate to the
  • Click on the Login link from the home/landing page
  • Identify email field and fill email id
  • Identify password field and fill password in the field
  • Click on the Login button
  • Assert and verify page title, url after login

While writing the Selenium test automation script, I have stored ChromeDriver.exe in the project folder itself. I can directly access it with “user.dir” and do not require to provide some other path. You can refer to the following screenshots for the location of Chrome Driver.


It is not mandatory to store ChromeDriver.exe in the project folder, you can store it in another folder or directory as well. In that case, you will have to provide correct path for the ChromeDriver.exe

You can find the test script for our test scenario below:

Upon executing the test script, it will open the browser and navigate to the home/landing page of LambdaTest website as shown in the screenshot below. While executing the test script, we can see the message “Chrome is being controlled by the automated test software” which means our test script is working with Chrome Driver.


Code Explanation:

  1. @BeforeTest:
    This section gets executed before the test execution starts. In this section of the code I have set the property and provided a ChromeDriver.exe file path and created an object to invoke the chrome browser. After that I maximize the browser window, then I invoked implicit wait and page load timeout which will avoid exceptions due to timeouts.
  2. @AfterTest:
    This section gets executed after the test execution is completed. After completion of the test, I closed the driver session.
  3. @Test:
    In this section, I perform actual tests and assertion/verification of results. Script navigates to LambdaTest home/landing page and clicks on the Login link.

    Upon reaching the login page, it will find the email field and enter the email id which we provide and also it will find the password field and enter password which we have provided in the script.

    Once both are entered, it will click on the Login button.

    After that user login successfully, it will assert the actual URL and title with the expected URL and title which we have provided.

    If the credentials provided are valid, then the test will pass and we can see the results as below. If credentials are wrong, then it will fail as in assertion actual and expected will not match.

Following screenshots show the result of the execution of the above test script.


b) By adding path in Environment Variable

In the above part I showed the execution of the Selenium test automation script using Chrome Driver, by providing a path of Chrome Driver in the test script itself.

There is another way as well, where I can set the path of ChromeDriver.exe in the system environment variable itself so that i don’t need to set the path in selenium test automation script explicitly.

Let us see how you can set that path in the system environment variables.

  1. Copy the path of the folder in which ChromeDriver.exe. If the entire path for ChromeDriver is
    “D:\AutomationPractice\Selenium\Project1\ChromeDriver.exe “
    Then we will consider folder path as
  2. Now open environment variables in Windows operating system, on Windows 10 search for ‘This PC’, right click on that and go to properties. And click on Advanced System Settings


  3. Click on Environment Variables and then go to System variables, select path and click edit (as shown in below screenshot)


  4. Click Edit and add path which we have copied in the first step and then save it by clicking ‘Ok’ and close all open windows with ok.

So I have saved the path for Selenium ChromeDriver in system variables, now we will execute our Selenium test automation script. But we will not require to set the property ChromeDriver path in the test script explicitly.
So we have made changes accordingly in the script.

Following screenshot shows the result after execution of the above test script as it shows that our Selenium test automation script is successfully passed using Selenium ChromeDriver.


How To Use Selenium ChromeDriver on Mac OS?

Now, we’ll perform test automation with Selenium ChromeDriver on Mac OS. After the zip file for Selenium ChromeDriver is downloaded, you can extract the application executable Chrome Driver file from it.


You can see the screenshot where downloaded and extracted executable ChromeDriver file from ChromeDriver zip file.

And I will store it in the eclipse project folder, so that I can use that in my selenium test automation script to invoke the chrome browser.


Now we can see how we will use that to invoke chrome browser and perform the same actions as we did in earlier cases.

As we have stored Chrome Driver in the project folder, it helped us to use it from there directly while invoking the browser.

Here, we have to notice that we just have to provide only the name Chrome Driver and not with its extension. Once the browser gets invoked and navigates to the LambdaTest home/landing page. It can be seen in the following screenshot.

We can also see the message ‘Chrome is being controlled by automated test software’, which shows that session is being controlled by Selenium ChromeDriver.


Following screenshots shows the successful execution of Selenium test automation script along with TestNG result.


Selenium ChromeDriver Using Maven Dependencies

So, in a practical scenario, while working in an organisation, you use some kind of build automation tools for test automation projects. Maven is a widely used build automation tool, ChromeDriver can be used with Maven dependencies as well.

If you are not aware of maven please refer to our article on Selenium testing with Maven to start with.

While using maven, you need to change the approach. You no longer require to download ChromeDriver explicitly. In this case, you can just add a dependency for Automation testing with Selenium ChromeDriver in the pom.xml file.

And this dependency can be downloaded from the maven repository website

Once you go to this website, click on the Selenium WebDriver version for which you want to download Selenium ChromeDriver dependency and then copy that dependency and paste it in the pom.xml file of your project.

Wrapping it Up

As Google Chrome’s popularity rises, so does the need to find automated browser testing of your web application on the Chrome browser. To perform Selenium test automation, you need a ChromeDriver to access the browser.

In this blog, we’ve explored how you can download ChromeDriver in Selenium and run test scripts both on Windows and Mac OS. One with, setting property explicitly in test script by providing ChromeDriver path and another one with setting system environment variable.

That’s all for now! I hope you are more wiser, when it comes to automation testing with Selenium ChromeDriver. Do share your views and opinions with us in the comment section below. Also, feel free to retweet this article and help us reach out to your peers. Happy Testing!!!
