Consider the case where an A/B test is set up to compare Episerver recommendations with your existing recommendations. In this case, set the abTestContent attribute in the tracking request to full, and define implementations for the info and smartRecs callback functions.
The smartRecs callback is called whenever a visitor is a member of the test group set up to show Episerver product recommendations. If the visitor is a member of the test group that is set up to show your own product recommendations, the smartRecs callback is not called.
Do not rely on the group property alone to decide when your own product recommendations should be shown. For example, you write your info callback to show your product recommendations whenever the visitor's group is set to A. When the current A/B test ends and another begins which compares two competing Episerver configurations, your site displays both Episerver and your own product recommendations to visitors in the A group.
