Mobile Emulation from msedge driver (Selenium)

Question

I was reading this page : https://learn.microsoft.com/en-us/microsoft-edge/webdriver-chromium/capabilities-edge-options
about how to use MS Edge's web driver, and among the capabilities of the driver, there seems to be an option for mobile emulation.

I know this option is available during regular use of the browser via devtools, but I can't get it to work using the automated web driver with selenium.

The page above states that information about the device should be passed via a dictionary in EdgeOptions, either by specifying the name of the device, or its metrics (screen size) and user agent. I tired both of these and couldn't get a result.

Any idea of what I might have missed to get this to work ?

Here's my code in python if you are interested :

mobile_emulation_specs = {  
"deviceMetrics" : "425px",  
"userAgent" : "Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.159 Mobile Safari/537.36 Edg/92.0.902.78"  
}  
  
mobile_emulation_name = {  
"deviceName": "Pixel 2"  
}  
  
options = EdgeOptions()  
  
options.use_chromium = True  
options.set_capability('mobileEmulation', mobile_emulation_specs) #doesn't work  
options.set_capability('mobileEmulation', mobile_emulation_specs) #doesn't work either  
  
driver = Edge(options = options, executable_path = edge_path)  
driver.get(url)  

Thank you very much in advance.

Hi @Luc Havelson ,

According to your description, you can try to use add_experimental_option to achieve your requirements, here is a simple sample code(part of your code):

from msedge.selenium_tools import Edge, EdgeOptions  
  
options = EdgeOptions()  
options.use_chromium = True  
  
mobile_emulation = {  
    "deviceMetrics": { "width": 375, "height": 812, "pixelRatio": 3.0 },  
    "userAgent" : "Mozilla/5.0 (Linux; Android 6.0; Nexus 5 Build/MRA58N) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.159 Mobile Safari/537.36 Edg/92.0.902.78"  
}  
options.add_experimental_option("mobileEmulation", mobile_emulation)  
driver = Edge(executable_path = r"C:\Users\Administrator\Desktop\msedgedriver.exe",options = options)  
  
driver.get('https://www.google.com')  

Note: You need to replace the executable_path according to your own situation, and ensure that the mobile device parameters are correct.

And this is result:
