Re: testing for keyboard accessibility

It's important to note that screen reader accessibility is not the same
thing as keyboard accessibility, and it's possible to have one and not the
other, which would make it inaccessible regardless.

E.G

With the below referenced span tag, without tabindex=0, it won't be keyboard
accessible, and without a keyDown handler, it won't be actionable from the
keyboard.

Also, without a click handler, it won't be accessible for screen reader
users via JAWS for example, and without role=link to indicate an accessible
role for the object, it won't be recognizable as an actionable element for
screen reader users either.

All of these pieces need to come together in order to ensure full
accessibility, and there really isn't a way to automate everything.

I wrote an article about this not too long ago with a similar example at
http://lnkd.in/jYnkZq
if it helps.
