FWIW ptest is enabled by default on the autobuilder (and in poky).

I think the missing piece of knowledge here is that most of our existing
tests (except ptest) are designed to be run by an external system
against a booted image. They're not intended to run within the image
itself. 

If you have the image booted, you can do something like "bitbake -c
testimage" with it having been configured to point at the booted target
for it to run those tests against the image.
