I am trying to do AB testing with workflow in Sitecore 8.1. I have already created the test variants in Test the Component Box. Those variants are also stored under the Test Lab in the Marketing Control Panel. But if i am trying to save the item those variants are not visible in experience editor and i am not getting any notification for submit or create test option. Can anyone please tell me what can be the reason and how i can get the Preview and start test dialog box. Is this any access/permission related issue?
