Test Automation on Microsoft Edge Browser using Selenium Web Driver

Microsoft Edge

Microsoft Edge, initially developed under the codename Project Spartan, is a web browser developed by Microsoft and included in the Microsoft Windows operating system. Officially released on July 29, 2015, for Windows 10. It replaced Internet Explorer, which was used as the default browser since Windows ‘95 release, as the default browser on Windows 10. It will also be the default browser of the forthcoming release of Windows 10 for smartphones and small tablets.

Microsoft Edge is designed to be a lightweight web browser with a layout engine built around web standards, removing support for legacy technologies such as ActiveX in favour of extensions and integration with other Microsoft services, such as the digital assistant Cortana and OneDrive; it also includes annotation tools and a reading mode.


Webdriver Support For Edge

Microsoft has announced support for automated testing of Microsoft Edge through the W3C WebDriver standard. To use WebDriver with Microsoft Edge, we need the Microsoft WebDriver server on  Windows 10. WebDriver is an emerging standard through which Web developers can write tests to automate Web browsers for site testing. It provides a programmable remote control for developing complex user scenarios and running them in an automated fashion against your website in a browser.

With this new capability, Microsoft Edge can be run through the same regression testing as other browsers, helping developers and testers to identify issues with less effort and making sites just work for the end users.

You can refer to the GitHub library for the desired capabilities in selenium for edge browsers for all the detailed methods and etc.


How WebDriver Works

1. WebDriver Server:

To get started using WebDriver, we need to have the first Microsoft WebDriver Server installed in our Windows 10 operating system to start with a new automation framework or to use the existing one. To download the Microsoft edge driver, click here.

WebDriver is disabled by default for security. In order to enable using WebDriver, you will need to download edge driver and install the Microsoft WebDriver in a location with your test repository. You should be able to use Microsoft Edge’s WebDriver implementation just like you would use any other browser’s implementation.

This server forms a link between Selenium and Edge Browser as shown in the following diagram:

2. Supporting Language:

After installation of the Microsoft Driver Server, we will have to choose the framework development language. Currently, the updates of web driver support have been submitted to C# and Java Selenium language bindings.

Selenium provides support for all the basic APIs of the Edge browser version 2.47.1 onward. Microsoft Web Driver for IE Edge supports xpath too.

3. Automation Framework:

A. Framework from scratch

If you are building the framework from scratch to be tested on Microsoft Edge then firstly download the language-specific selenium client. And import it within the project. Here we will use java as a framework development language.

Step 1 -> Set System property for edge driver.

Set System property for edge driver

Step 2 ->If you want to change the default page load strategy of edge browser which is normal by default you can use the following code snippet 

Set System property
Set System property

Step 3 ->Get the object of Edge browser as follows

Using this driver instance you can access the different objects with the help of different locators on the website you want to automate. Except few, most of the locators will work for the Edge browser. These options will be discussed in the next section in detail.

B. Existing Framework to run on Microsoft Edge:

Older version of Selenium 2.53.1 use to provide good support for most of the features that we have available for the other browsers to date. So you will not be able to run the existing framework on the edge browser directly.

As per the old release of Selenium 2.53.1

Locators supported: id, css, cssSelector, name, tagName, xpath, linkText, partialLinkText, tagName

Functionality supported: Maximize screen, full-screen window, getting window handles, size, and handling alerts is also supported with the latest versions of IE Web driver.


Key Features of the Latest Selenium WebDriver 4.21.0 for Edge

1. Enhanced WebDriver Server: Selenium 4.21.0 introduces an updated WebDriver server for Microsoft Edge, ensuring seamless communication between Selenium and the Edge browser. This improved server enhances stability and performance, crucial for large-scale test automation projects.

2. Expanded Language Support: Selenium 4.21.0 extends language bindings support to include popular programming languages such as Python, Ruby, and JavaScript, in addition to C# and Java. This broad language support empowers developers to leverage their preferred programming languages for test automation on Microsoft Edge.

3. Advanced Locator Strategies: The latest release of Selenium introduces refined locator strategies, enabling precise element identification on web pages. With support for dynamic XPath and CSS selectors, developers can create robust test scripts optimized for Microsoft Edge.


Best Practices for Test Automation on Microsoft Edge:

1. WebDriver Installation: Begin by installing the latest version of the Microsoft WebDriver server compatible with Selenium 4.21.0. Ensure proper configuration to establish a seamless connection between Selenium and Microsoft Edge.

2. Framework Development: Utilize existing test automation frameworks or develop custom frameworks tailored to Microsoft Edge. Leverage Selenium WebDriver’s comprehensive APIs and advanced features to create efficient and maintainable test scripts.

3. Cross-Browser Testing: Incorporate cross-browser testing into your automated software testing services to validate application functionality across different browsers, including Microsoft Edge. Selenium’s multi-browser support ensures consistent behavior across diverse browser environments.

      Hi Purushottam..
      You can try this for your problem.

      System.setProperty(“webdriver.edge.driver”, “C:\Program Files (x86)\Microsoft Web Driver\MicrosoftWebDriver.exe”);
      EdgeOptions options = new EdgeOptions();
      driver = new EdgeDriver(options);


    • Aravindhan

      Hi Purushotham,

      You missed the double quotes at the end. it should be driver.get(“http://google.com”)

  • Uttam Basak


    I am using groovy to develop testing framework using Selenium. I want to switch driver from main page to a pop-up window but I could not able to do. I have seen that driver.getWindowHandles() does not work using edge driver and edge browser. driver.getWindowHandles() always returns 1 window handler i.e. main page. Is there any capability that I am missing to capture pop-up window? Any help would be appreciated. Thanks.
