During an A/B test, Engagement Cloud judges individual test cases by the frequency of certain events for user sessions that are assigned to each specific test case. An event can be the retrieval of a specific page, but it can also be a custom event that the web browser generates.

After you define a custom event template in Engagement Cloud, a JavaScript call sends such events:

bysideWebcare_event('checkOutPageReached', {});

where

You are free to send these events whenever you like, but avoid calling this method in an onClick handler for a hyperlink, because the browser might leave the current page before having sent the event to the Engagement Cloud server.
