Test Recording
There are two ways to initiate recording. You can either launch a new browser instance with the recording toolbar attached, or you can attach the recording toolbar to an existing browser instance (or WPF application).
Launch New Recording Browser
Click the Record button to launch Internet Explorer with the recording toolbar attached. Use the recorder to record your test actions and verifications. Use Ctrl+R as a keyboard shortcut.
Note: Web Test recording is only supported in Internet Explorer.
Attach to Existing Instance
Click the drop-down arrow on the Record button to see a list of available browser instances or WPF applications. Select one to attach the recorder to that instance.
 Web Test |  WPF Test |
Note: You cannot connect to an existing Silverlight Out-of-Browser application for Out-of-Browser tests. Stop Recording
To end recording, simply close the IE window or WPF application that has the recording toolbar attached.
