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 will use to view the page.
In a multisite environment, if you specified that the test should run on all sites, select a Site on which to preview the test.
If you specified that the test should run on only one site, the test is automatically previewed on that site.
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.
