This documentation is not using the current rendering mechanism and is probably outdated. The extension maintainer should switch to the new system. Details on how to use the rendering mechanism can be found here.
What does it do?¶
This extensions offers a plugin to perform A/B testing of content elements. You can configure a pool of content elements to be shown and how many content elements should be shown at a time. The elements are evenly shown. A user gets the same elements shown every time he visits the page again till the configured expire time is met. After that the procedure starts again which means a new set from the content elements is selected for the user.
