This document discusses automated analytics testing and A/B testing. It provides an overview of web analytics and user analytics. A/B testing is described as testing changes to a small portion of users first to avoid regressions. Examples are given of how analytics could be wrong, such as showing the wrong discount code. The document argues that QA personnel should test analytics to prevent data loss and ensure the correct information is captured. It proposes adding an extra HTTP request to intercept analytics data during testing to validate the key-value pairs match expectations.
