Accessible Name Automation (Proof of Concept)

This is an experiment based on set of changes to HTML and related standards called Accessibility Object Model (AOM).

It mainly uses the experimental global method window.getComputedAccessibleNode(node).

Such project tries to demonstrate that it is theoretically possible (in a certain way) to predict what the screen reader will say by focusing on semantic and non semantic elements with a bit of automated testing, thus reducing the need for manual testing.
