Echo JS 0.11.0

Nice writeup... I would point out that these kinds of tests can be somewhat costly and very time consuming in terms of the time they take to run.

Depending on your workflows, you may want them earlier or later in your lifecycle.

Another point worth mentioning, is that you will want to consider device/viewport configurations as well.  I use my phone (Android) with Text Accessibility cranked to max because of visibility issues that glasses won't correct.  I cannot tell you how many times I will face a mobile dialog or other content that is completely unusable/broken for me.  The other issue is having things forced too small, though the PS's triple-tap zoom helps significantly there.

Of course the Accessibility rabbit hole is an adjacent topic beyond the minimum viewport testing.
