To run A/B tests that test your current setup or existing recommendations against Optimizely recommendations, request additional A/B test information by adding the abTestContent property.

Name	Description and usage
abTestContent	[Optional] [String] Activate A/B test output. - summary – Returns only A/B test name and the page visitor's group. - full – Returns all available information. If you specify the property name with an empty string, summary is used by default.

To request full A/B test information, set the abTestContent attribute in the tracking request to full, as shown below.

{    
      "type"          : "home",
      "ip"            : "10.42.37.139",
      "session"       : "new",
      "cuid"          : "new",
      "site"          : "retailer",
      "clientToken"   : "1234abcd5678",

      "info"           : {
         "abtest" : [{
           "smartRecs" : [{
             "name"    : "a/b test",
             "group"   : "A",
             "configs" : {
                           "A": [{
                                   "name"     : "homeA",
                                   "position" : "homejson"
                                }],
                           "B": [{
                                   "name"     : "homeB",
                                   "position" : "homejson"
                                }]
                         }
           }]
         }]
      }
    }

To request only the name of the A/B test and the group of the page visitor, set the the tracking request's abTestContent attribute to summary.

{      
      "type"          : "home",
      "ip"            : "10.42.37.139",
      "session"       : "new",
      "cuid"          : "new"
      "site"          : "retailer",
      "clientToken"   : "1234abcd5678",
      "channel"       : "web",
      "lang"          : "en-gb",
      "currentURI"    : "www.retailer.com/home",
      "previousURI"   : "https://www.google.co.uk/?gws_rd=ssl#q=retailer",

                     }]
      }
    }

Note
Each product can have different A/B groups. So, do not assume that a visitor in group A for recommendations is also in group A for another Optimizely product, such as, Optimizely Promote (legacy).
