How to run Selenium tests on Chrome using ChromeDriver?

Google Chrome dominates the browser market with a massive 64% global market share. With several useful features, it is one of the most preferred browsers in the world. Given its importance and usage, testing all websites on Chrome becomes crucial.

This article will explain how to perform Selenium tests on a Chrome browser using ChromeDriver. But before that, let’s understand what ChromeDriver is and how users can configure it on their systems.

What is a Selenium ChromeDriver?

A ChromeDriver is a standalone server or a separate executable used by Selenium WebDriver to control Chrome. Running Selenium test scripts on the Google Chrome browser is impossible without ChromeDriver. One can easily initialize the object of ChromeDriver using the following command:

WebDriver driver = new ChromeDriver

How to download ChromeDriver for Selenium?

You can download ChromeDriver for Selenium as per the ChromeDriver version using its official website. Here are the steps given below:

Steps to download ChromeDriver version 115 and above

Navigate to ChromeDriver official site for downloading the latest ChromeDriver.

For Chrome browser version 115 and above, click on “the Chrome for Testing availability dashboard” which will navigate to Chrome for Testing Dashboard.

This page has various versions for Stable, Beta, Dev and Canary releases for Windows, Mac and Linux operating system. Click on Stable link and look for ChromeDriver Win32 or Win64 (based on the Windows OS system type).

Open the URL in the new browser window and ChromeDriver will be downloaded in zip format. Extract the content and move it to the desired location. (Preferably at the root location of the automationproject).

Steps to download ChromeDriver version 114 and below

Assuming the current system is Windows, click on “chromedriver_win32.zip”.

Now, we have the desired ChromeDriver downloaded depending on our Chrome browser version, let us see the 2 ways by which we can configure ChromeDriver via environment and System.setProperty() method of Java.

How to configure ChromeDriver?

You can configure ChromeDriver using different methods

Steps to configure ChromeDriver via Environment Variable

On Windows operating systems, we can declare system level variables by using Environment variables. Below steps will help you set up the environment variable for Chrome Driver. Whenever an instance of the WebDriver is created in Selenium script, it will automatically detect the path of the ChromeDriver from the system variables.

Open Environment variable pop up by directly searching for “Environment Variables” from Windows Search. This will open “System Properties” pop up. Click on the “Environment Variables” button.

On Environment Variables pop-up’s System Variables section, click on Path variable and click on the Edit button.  

On the Edit environment variable pop-up, click on the “New” button and add the ChromeDriver executable location. Click on OK to save the configuration. 

driver = new ChromeDriver();

This will automatically detect the ChromeDriver path from the system variable.

Configure ChromeDriver via System.setProperty method

ChromeDriver can also be configured by explicitly specifying the ChromeDriver path in the test script.

System.setProperty accepts key value pair where key would be “webdriver.chrome.driver” and value would be the path of the ChromeDriver exe path.

System.setProperty("webdriver.chrome.driver", "D:\\BStackDemo\\chromedriver.exe");

Now let’s consider a test case example wherein we want to perform 2 simple steps:

Refer to the code snippet below to get a better sense of executing the steps mentioned above:

import org.openqa.selenium.WebDriver; import org.openqa.selenium.chrome.ChromeDriver; public class ChromeTest { public static void main(String args[]) { WebDriver driver; //Setting system properties of ChromeDriver System.setProperty("webdriver.chrome.driver", "D:\\BStackDemo\\chromedriver.exe"); //Creating an object of ChromeDriver driver = new ChromeDriver(); //launching the specified URL driver.get("https://bstackdemo.com/"); } }

If you are configuring ChromeDriver via the environment variable, delete the System.setProperty() line from the above code and it should work.

Run Selenium Tests using ChromeDriver

• Although it’s vital to test web-apps for Chrome, it’s also important for a web app to be optimized for other browsers like Firefox, Safari, Edge, etc.
• Teams can leverage  BrowserStack, which enable QAs to perform cross browser testing for their web apps across thousand of real browsers and browser versions like Safari, Opera, Edge, etc.
• All real browsers are installed on real desktop and mobile devices, thus providing the optimal environment for software testing in real user conditions.
