I am doing automation testing on the app which launches url inside (webview2 ) with login info , how to connect with that

[pooja1233]

I tried open browser but it opens url inside but with different instance , if I click manually on that it load webpage , how to do that through automation

Hey @pooja1233 - Can you read the instructions on this page and see if it helps?
https://docs.microsoft.com/en-us/microsoft-edge/webview2/how-to/webdriver#approach-2-attaching-microsoft-edge-driver-to-a-running-webview2-app

If not, please let me know.

Thanks!

No i was was following that document but no success , so I launch app with
Set environment variable WEBVIEW2_ADDITIONAL_BROWSER_ARGUMENTS --remote-debugging-port=9222
win = Windows()
win.open_from_search("app","App name")
elements = win.get_window_elements()

once application open , I can see webpage loaded inside it
now to connect to that instance I am using

def create_edge():
options = EdgeOptions()
options.use_chromium = True
options.use_webview = True
options.binary_location = r"app location"
options.DebuggerAddress = 'localhost:9222'
driver = Edge(,options = options)

but this is opening new instance of the edge inside the app , I need to connect what launches manually

Your code looks a bit different then what's described for the options here:
https://docs.microsoft.com/en-us/microsoft-edge/webview2/how-to/webdriver#attaching-microsoft-edge-driver-to-the-launched-webview2-app

What version of Selenium are you using?

[pooja1233]

I have 3.141.0
I am using robot framework

[champnic]

I'm unfamiliar with the robot framework, but I believe you need to be using Selenium version 4.0+.

[pooja1233]

I did update selenium to 4.0 but still its not working , do you have any example in python hoe to connect to existing session , or how to open an webview app with url , I was trying to use Zoomba.GUILibrary open browser but it again use another instance

[pooja1233]

I can grab process id pf webview app and inside there is webview2.exe , i can get port number too , I tried to connect through port number too but no luck

[champnic]

I don't think we have specific examples of this scenario, besides what's in the doc I posted. @bwalderman Any ideas?

[bwalderman]

Hi @pooja1233 , please remove options.use_chromium which is no longer necessary in Selenium 4. Please also remove options.use_webbiew and options.binary_location. These options should only be used if you want WebDriver to launch your app. Lastly, in Python, the name of the option to use for attaching is debugger_address instead of DebuggerAddress: https://www.selenium.dev/selenium/docs/api/py/webdriver_chromium/selenium.webdriver.chromium.options.html#module-selenium.webdriver.chromium.options

Here's an updated sample which should work:

def create_edge():
options = EdgeOptions()
options.debugger_address = 'localhost:9222'
driver = Edge(options = options)
