 * "tested" by analyzing the data they generate including on some known pages.
 * Feel free to add tests for counters where the triggering logic is
 * non-trivial, but it's not required. Manual analysis is necessary to trust the
 * data anyway, real-world pages are full of edge-cases and surprises that you
 * won't find in unit testing anyway.
