#2 Selenium 4 - Emulate Device Screen dimensions with Chrome Devtools for Responsive Testing

[@rashmib3343]

Thank you sir, this is one of the best feature in selenium. Your explanation is awesome and waiting for the next session. I will definitely implement this into my framework.

@rahul When clicked on the navigation menu and after going to that clickable screen, the screen size becomes the default, do you know why it is happening?

[@shri3222]

This not a actual emulator, you are just changing the screen size. When we are using emulator there will be a user agent for every device so that it's mimic the device depending upon user agent and user agent is different for every device.

Hello sir Video is useful but i am afraid in this way it is just adjusting the view point as per the mobile device but nor rendering properly as we manualy do with Inspect -> Mobile view In my project there is an iFrame and when i use emulation then it is looking like an adjusted browser window but it is not same with Inspect -> Mobile view

[@iqrabibi8904]

yes had the same problem, did you find any solution to that?

[@keplervelasco1854]

is this available with python?

[@keplervelasco1854]

ok by watching the session 3 of your course, I was able to emulate mobile execution with selenium 4 and python by doing this!: set_device_metrics_override = dict({ "width": 600, "height": 1000, "deviceScaleFactor": 50, "mobile": True }) driver.execute_cdp_cmd('Emulation.setDeviceMetricsOverride', set_device_metrics_override) great course!! thanks a lot Rahul!! :)

@@keplervelasco1854 Does that mean we don't need Appium now?

[@keplervelasco1854]

@jatin Sharma, I think for responsive apps we can follow this approach and would not need appium, however for native apps in which we need to install apk we would still need appium...

[@nobeetee]

@@keplervelasco1854 Thanks for the prompt response, much appreciated. I am having issues while setting up Appium at my work place. I am following Rahul's Appium course. But I am struggling with invoking the app itself. It's such a set back for me.
