In reply to Guido.

It covers as many parts as it can but there are still a few things it doesn't have the ability to test by just scanning the code.

Skip links are hard to test they Keyboard navigation I don't even know how to test that while it's unrendered code.

I had my fingers crossed you might have known how but from trying to figure it out myself I know there isn't a simple code solution. It's not super efficient but the best tool right now for it is a human with a browser and a keyboard :)
