Idea being that either Robot Ninja would provide a list of DOM attributes that it expects the website to have.E.G. add to cart button with a class .js-add-to-cart, and cart count wrapper with and ID or #cart-count which could be based on default WooCommerce templates.
Provide a way for the users to define its own DOM attributes to allow the test to pass.
This might also be helpful in future proving the product as WooCommerce continues development and their own internal templates change. As stores can't alway update to the latest version of woo.
