Follow these steps to preview a test.
Edit the test and open the Test Groups tab.
Click the Preview button for the test group whose test elements you want to preview.
Select a Preview User, whose profile you’ll use to view the page.
Select the desired preview URL (if more than one is available).
Note: If a System Default Preview URL or a Test Default URL is set, these URLs will be listed as choices on this screen.
Click OK.
A countdown screen displays while the preview loads. It can take up to a minute for the preview to load. When the count down is complete, a new browser window opens and displays the specified URL, with the test elements running.
End the Preview by returning to the ATG Campaign Optimizer UI and clicking End Preview.
