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).
Click the Record button or press CTRL+R.
Choose the recording browser.
Note: As of the 2014.4.1211 version Safari cannot be used for test recording.
If you enable Save my choice for the future, the Record button in Test Studio Standalone will display the icon for the default browser.
You can select a different recording browser later from the Record button drop-down.
3. Enter a URL and press Enter/Start Recording button. A recording step is added to the Steps pane and the recorder is attached to the browser.
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.
You cannot connect to an existing Silverlight Out-of-Browser application for Out-of-Browser tests.
To end recording, simply close the IE window or WPF application that has the recording toolbar attached
4. Compare Mode determines which mode to use when adding a page node to the Elements Explorer. Compare Mode can be checked against the page's Title or one of multiple settings that look at various parts of a URL. Please see this article for more information.
