title: "addGlobalAssertion"
description: "Adds a named assertion to the collection of assertions to be executed before test actions.

This API is intended to be invoked by assertion frameworks to register assertions that must hold
on the entire application whenever it's fully loaded and ready to interact with. They will be
invoked upon common actions such as `performClick`, and they always verify every element on the
screen, not just the element the action is performed on.

This is particularly useful to automatically catch accessibility problems such as contrast ratio,
minimum touch-target size, etc."
