Selenium Tools for Microsoft Edge

Build Status

Selenium Tools for Microsoft Edge extends Selenium 3 with a unified driver to help you write automated tests for both the Microsoft Edge (EdgeHTML) and new Microsoft Edge (Chromium) browsers.

The libraries included in this project are fully compatible with Selenium's built-in Edge libraries, and run Microsoft Edge (EdgeHTML) by default so you can use our project as a seamless drop-in replacement. In addition to being compatible with your existing Selenium tests, Selenium Tools for Microsoft Edge gives you the ability to drive the new Microsoft Edge (Chromium) browser and unlock all of the latest functionality!

The classes in this package are based on the existing Edge and Chrome driver classes included in the Selenium project.

Before you Begin

The Selenium Tools for Microsoft Edge is a solution for developers who prefer to remain on Selenium 3 which is the current stable release and developers who have existing browser tests and want to add coverage for the new Microsoft Edge (Chromium) browser without changing the Selenium version.

The very same Edge driver classes provided in this package are included in Selenium 4 and are already available today in the latest Selenium 4 Alpha release. If you are able to upgrade to Selenium 4 Alpha, there is no need to use this package as Selenium should already have everything you need built in!

Getting Started

Downloading Driver Executables

You will need the correct WebDriver executable for the version of Microsoft Edge you want to drive. The executables are not included with this package. WebDriver executables for all supported versions of Microsoft Edge are available for download here. For more information, and instructions on downloading the correct driver for your browser, see the Microsoft Edge WebDriver documentation.


Selenium Tools for Microsoft Edge depends on the official Selenium 3 package to run. You will need to ensure that both Selenium 3 and the Tools and included in your project.


Add the Microsoft.Edge.SeleniumTools and Selenium.WebDriver packages to your .NET project using the NuGet CLI or Visual Studio.

npm install @microsoft/edge-selenium-tools

Use pip to install the msedge-selenium-tools and selenium packages:

pip install msedge-selenium-tools selenium==3.141

Example Code

See the Microsoft Edge WebDriver documentation for lots more information on using Microsoft Edge (Chromium) with WebDriver.


using Microsoft.Edge.SeleniumTools;

// Launch Microsoft Edge (EdgeHTML)
var driver = new EdgeDriver();

// Launch Microsoft Edge (Chromium)
var options = new EdgeOptions();
options.UseChromium = true;
var driver = new EdgeDriver(options);


const edge = require("@microsoft/edge-selenium-tools");

// Launch Microsoft Edge (EdgeHTML)
let driver = edge.Driver.createSession();

// Launch Microsoft Edge (Chromium)
let options = new edge.Options().setEdgeChromium(true);
let driver = edge.Driver.createSession(options);


from msedge.selenium_tools import Edge, EdgeOptions

# Launch Microsoft Edge (EdgeHTML)
driver = Edge()

# Launch Microsoft Edge (Chromium)
options = EdgeOptions()
options.use_chromium = True
driver = Edge(options = options)


We are glad you are interested in automating the latest Microsoft Edge browser and improving the automation experience for the rest of the community!

Framework to automate tests using Selenium WebDriver (lighten version without selenium drivers)


Bellatrix is a cross-platform, easily customizable and extendable .NET test automation framework that increases tests’ reliability.


Wrapper over Selenium WebDriver for .NET


Liberator Driver works as an abstraction layer over Selenium WebDriver. Liberator uses Expected Conditions to avoid the race conditions common when automating a user interface, thereby ensuring a more efficient performance. Every setting of the individual driver types can be set using preferences, enabling the dependent frameworks built on its functionality to fine tune their performance. Errors in browser interaction are correctly trapped for all Selenium methods.
