Right, I see. The unattended runtime execution of ptests should be 
performed by meta/lib/oeqa/runtime/cases/ptest.py, I don't at the moment 
remember how the pieces fit together exactly so that it runs, but I 
think if you follow what it says [1] and run bitbake -c testimage 
<image> then it should work.

     @skipIfNotFeature('ptest', 'Test requires ptest to be in 
DISTRO_FEATURES')
     @skipIfNotFeature('ptest-pkgs', 'Test requires ptest-pkgs to be in 
IMAGE_FEATURES')
