Configure a Responsive Web Test

Using the Device Mode of Chrome and Edge Chromium browsers you can simulate different mobile devices and check how a web page behaves on these. With its Responsive Web test Test Studio provides the capability to record and execute tests against such emulated device mode.

The Responsive Web test in Test Studio is a separate type of test, which require some additional settings in order to correctly simulate mobile devices in the Device Mode of Chrome or Edge Chromium. This article describes the necessary adjustments in order to test a web page on a simulated mobile device.

The default pre-selected option is to manually choose the width and height of the device display to simulate. The preset values are 100/100 and you can enter the desired values in the respective fields. The User Agent field allows you to modify the User-Agent request header used from the browser for identification toward server and network peers. If left blank, the browser will use its default user agent.

Elements in the Responsive Web Test

The Responsive web test is using the same elements as a standard web test. That said, if the page under test uses the same elements in its responsive view, you can reuse already recorded steps from a web test and paste these into the newly created responsive one.

Note! The elements may look different in the desktop and responsive version of the web page and you may need to additionally adjust the images for the these, when searched by image.
