Integrate LambdaTest with your favorite tool and save yourself from manually managing bugs and tasks. Also fits with your CI/CD pipeline.


Most of our ELearning Course testing projects, we use cloud test tools to test the courses on multi OS/platforms. For example: If a tester wants to test an application on Windows 10 and macOS, then the tester needn’t use two physical desktops (one for Windows and another for macOS). Just open two cloud real time testing instances and perform the testing. This eases and speeds up your testing on multi OS and browsers.

LambdaTest provides cross browser testing support on real mobile devices and Desktops and it has a comprehensive list of mobile devices. For desktops, we can see Windows and mac OS options. However, Linux is missing in the supported platforms. We would strongly recommend LambdaTest if you are testing web applications on multi browsers and mobile devices.Suggestion to LambdaTest-Please add Real Time testing for Native Mobile Apps as well.

In LambdaTest Real Time Testing session, you can mark bug by entering comments & drawing on a screenshot, change screen resolution in the middle of your testing session. Screen video recording is also possible.


LambdaTest has three features for Visual UI testing. Screenshot, Responsive, and Smart Testing.

ScreenshotThis is a notable feature in LambdaTest. You can take screenshots for a given URL on 25 mobile/desktop browsers in one go. Once the screenshots are ready, the tester can validate them one by one in slider view.

ResponsiveAnother important feature. You can perform responsive mobile app testing on multiple devices simultaneously.

Mobile Responsive Testing

Smart TestingSmart Testing is a feature to compare screenshots with baseline images.


You can send Selenium browser commands using LambdaTest’s Remote URL and desired capabilities as shown below.

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability("build", "your build name");
capabilities.setCapability("name", "your test name");
capabilities.setCapability("platform", "Windows 10");
capabilities.setCapability("browserName", "Chrome");

LambdaTest supports Java, JavaScript, Python, C#, Ruby, and PHP to run your automation scripts on 2000+ different browsers.

Running Test WebDriver Selenium in Different Browsers

  1. Chrome Browser 

Download the driver from this link for Chrome. Chrome launching is easier when compared to other browsers.

Set system property WebDriver driver = new Chrome (); directing to the path of the ChromeDrive.exe file

Instantiate the ChromeDriver class

Alternatively, follow these instructions and do the same without any coding.

Click My Computer → Right Click on the Empty Space to get the properties → Click on Properties → Change Settings → Advanced → Environment Variables → System Variables → Path → Edit

In the edit, the tab doesn’t delete anything instead include a semicolon at the end and mention the path of the ChromeDriver.

Make sure you download the latest Chrome browser and the latest ChromeDriver.exe to avoid any errors.

  1. Internet Explorer 

Download the driver using one of the links based on your system compatibility.The class InternetExplorerDriver is used to control the browser. The process is the same as that of doing it for a Chrome but mentions the correct path.

  1. Safari

Download the Safari extension and then click the folder where you downloaded the file and double click on it to choose Install. After installation open preference pane and enable WebDriver browser extension. Restart the browser. You’re good to go.

  1. HTML Unit

HTML Unit driver does not have a GUI and it runs internally. Usually, this browser is not suitable for testing as it cannot do all functions as the others do. But, it is faster and lightweight WebDriver implementation can be used to test data.

It is not required to install any extra APIs but use the Selenium server’s detached jar file. HTML Unit Driver also captures the screenshots concurrently when the test is running.

Do not use it for javascript developed applications as it is not compatible.

  1. PhantomJS

This is also a driver that does not require GUI and hence called headless browser. Javascript API is used and web pages can be accessed easily. GhostDriver jar files can be downloaded here. Alternatively, use this link to download integrated PhantomJS and GhostDriver exe file. Also, download PhantomJS Driver and set the property file using the path and execute the script.
