Metrics Platform Technical Task
A/B testing is an integral part of the process of developing features for end users. Say a change has been made to a menu, moving it out of the menu and into its own button on the page. How could we know that this change resulted in the menu item being clicked on more or less often? To this end, we would like to use an experiment framework that will allow us to trial this feature on a small subset of all user traffic.
Your task is to implement a basic experiment framework that will permit a software engineer (herein "the experimenter”) to carry out such an experiment.
Setup
This repository contains a basic Slim 4 app. The app has one endpoint, GET /, which is defined in
public/index.php. You will be implementing the basic experiment framework within this app.
