aMustHaveTitle accessibility test not necessary

[edtechdev]

(Forgive me, I don't have UDOIT running. Please delete/ignore this if aMustHaveTitle is already disabled) There doesn't seem to be a basis for the aMustHaveTitle accessibility test. Screen readers ignore the title attribute on links by default, for example.

The code for the test is on line 371 here: https://github.com/ucfopen/UDOIT/blob/master/lib/quail/quail/common/accessibility_tests.php

It's been requested to be removed from the quail library UDOIT uses, but development on quail has ceased for a long time now, so the issue is still open:
quailjs/quail#363

W3C HTML5 recommends against using the title attribute:
https://www.w3.org/TR/html/dom.html#the-title-attribute

And here are a few articles about not using the title attribute in links for accessibility purposes:

On the quail github page, since they are no longer actively developing it, they recommend to use the axe library instead. I don't see any evidence that the axe library tests for a title attribute in links:

Hi Doug, that test is indeed disabled for UDOIT and only exists in the code from the quail library. Thanks for the concern!
