As of September 2020, Microsoft Edge holds 8.84% of the browser market and stands at the second position after Chrome. But still, while performing Cross Browser Testing, our main focus tends to revolve around browsers like Chrome, Firefox, or Safari primarily. But what about other browsers, like Edge?

While testing a website, it is quite important that it is rendered smoothly and accurately over all browsers, devices, and machines. Suppose you created a website and tested it on browsers like Chrome, Firefox, and Safari manually, and decided to deploy it. But what if the users open the website in Microsoft Edge, or in a version of browsers other than the tested ones ?

Therefore it is quite important to perform Automated Browser Testing, to test your website across multiple browser-version combinations, so as to ensure efficient user experience, with the help of Selenium. In this tutorial, we will dive in-depth on how to perform automated browser testing with Edge and Selenium in Python. We will be using the Edge WebDriver to help us run our Selenium automation test scripts over the Edge browser.

Download Selenium Edge WebDriver

While performing automated browser testing, it is important for the test scripts to communicate with the browser. Without having a WebDriver, this might not be possible. The Selenium Edge WebDriver works as the mediator between your code and the browser, which helps to provide the programmable remote control of the browser.

You can download the latest version of Selenium Edge WebDriver using this link.

Performing Browser Automation With Edge And Selenium In Python

Let us see what are the prerequisites to use Edge with Selenium and Python for browser automation:

  • Download the latest version of Python, if not already installed, from here.
  • Next, we need the Microsoft Edge browser. You can use this link to download it. Please note the version that you are downloading, for WebDriver purpose. If you have Edge already installed, you can find out its version by typing the below command in Edge’s address bar:
    • edge://version/
  • You can also find out the version of your Edge browser, using the below steps:
    • Open the Microsoft Edge browser.
    • Select Settings and more at the top right of the browser and go to Settings.
    • You can see a section About Microsoft Edge at the bottom of the settings tab, that contains the information about your Edge’s version.

Now that the basic setup is ready, let's proceed to the next steps to download and install the following:

  • Selenium framework for Python – Execute the below command in the terminal, after you have already installed Python language, to install the latest version of Selenium framework for Python language:
pip3 install selenium
  • Edge WebDriver for Selenium – Download the Edge WebDriver executable from this link that matches your system’s configuration. Make sure to download the version of the driver based on the version of Edge installed in your system. Unzip the file and copy the location of the msedgedriver.exe.
  • Selenium tools for Microsoft Edge – Execute the below command from the terminal to download the Selenium tools for Microsoft Edge directly:
pip install msedge-selenium-tools selenium==3.141

We are all set. Now we can perform automation testing with Edge and Selenium in Python. Let us see some examples.

Running Your First Automated Browser Testing Script

In this example, we will see how to write the first script that initiates the automated browser testing with Edge and Selenium:

# importing required package of webdriver
from selenium import webdriver
# Just Run this to execute the below script
if __name__ == '__main__':
   # Instantiate the webdriver with the executable location of MS Edge web driver
   browser = webdriver.Edge(r"C:\Users\LenovoE14\Downloads\edgedriver\msedgedriver.exe")
   # Simply just open a new Edge browser and go to

In this code above, we are just creating the WebDriver instance for Microsoft Edge, by passing the path of the executable Edge WebDriver as parameter. In this case, it is C:\Users\LenovoE14\Downloads\edgedriver\msedgedriver.exe. Then we are opening a new Edge instance with a provided URL. You can customize the URL as per your choice.

Execute the above code and you will see an instance of the Microsoft Edge getting started with '' in its address bar (because we have provided this address to the webdriver instance and asked the browser to open it):

First script executed

Performing Browser Automation Using Web Locators

Let us now look at another example, to perform some specific actions, with the help of web locators. In this example, we will try to insert the email address at the home page of and click on the button Start Free Testing, as shown in the below image:

Start free testingCopy and paste the below code in your IDE/Text editor and run it:

# importing required package of webdriver
from selenium import webdriver
from import Options
from time import sleep
from import expected_conditions as EC
from import By
from selenium.common.exceptions import TimeoutException
from import WebDriverWait
from selenium.webdriver.opera.options import Options
from import WebDriverWait

if __name__ == '__main__':
    # Instantiate the webdriver with the executable location of MS Edge
    browser = webdriver.Edge(r"C:\Users\LenovoE14\Downloads\edgedriver\msedgedriver.exe")
    # Simply just open a new Edge browser and go to
        # Get the text box to insert Email using selector ID
        myElem_1 = WebDriverWait(browser, 10).until(EC.presence_of_element_located((By.ID, 'useremail')))
        # Entering the email address
        # Get the Submit button to click and start free testing using selector CSS_SELECTOR
        myElem_2 = WebDriverWait(browser, 10).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "#testing_form > div")))
        # Starting free testing on LambdaTest
    except TimeoutException:
        print("No element found")

In the code above, we have inserted the email address in the text box shown above and pressed the button Start Free Testing. We have used the selectors ID and CSS SELECTOR for this. Upon execution, a new instance of Microsoft Edge will open and perform the following actions in the given order:

New instance of Microsoft Edge will be launched:

Microsoft Edge instance launched using SeleniumThe browser will get maximized (as we execute the browser.maximize_window()):

Browser Maximized

The LambdaText homepage will open:

Home page opened

Given email will be inserted in the text box and the button Start Free Testing will be pressed:

You'll be redirected to the login page to set up your account and start your cross browser testing with the help of LambdaText:

  • What is Edge WebDriver and how to get it.
  • How to set up automated browser testing with Edge and Selenium in Python.
  • Writing the first browser automated test.
  • Using Selectors to perform browser automation with Edge and Selenium in Python.

The popularity of Microsoft Edge is constantly rising. We have performed the browser automation using an installed version. But what if we need to perform this in some other version, or some other Windows OS version?

In such a scenario, downloading and testing each version might not be possible, thereby leading to certain drawbacks or some user experience issues later. To overcome this, we can use LambdaTest for cross-browser testing. LambdaTest will not only allow you to test your website on multiple browsers and operating system combinations but will allow you to perform parallel testing as well on cloud Selenium Grid.

LambdaTest provides a platform to perform live interactive browser compatibility testing of your public or locally hosted websites and web apps on 2000+ real mobile and desktop browsers running on real operating systems.
