Best would be to not shoot on a bright day, but on an overcast day. This makes the lighting the most uniform and repeatable.
Also, you should perform the test a number of times per camera/lens combination, and middle the results.

Uniform, yes, repeatable, no. The intensity still varies a lot with cloud thickness.
But as you already mention, there's a lot more to test to fully cover AF performance. That's another reason why we don't do it.
