A/B testing Django CMS with the ability to select pages for testing. How can this be implemented?

Question

Django

Good afternoon, dear users!
I would like to know about A/B testing.
There is a project on Django CMS 1.11
. The functionality for displaying various information (separate applications) is also implemented.
What I want to do:
Create a page, place the "A / B testing" application on it, in the settings of which I will specify the pages that will participate in the test. It is necessary to implement the ability to customize the application, for example, the probability of issuing one page (30% / 70%), while it is necessary to save the URL, some other settings are possible, this is not important now.
