[yocto] i assume "ptest" is an all-or-nothing selection, yes?

  i thought as much, just wanted to make sure. and while that might be
obvious to many people, i think a short note at the beginning of that
section wouldn't hurt, but a couple more questions about ptest so i
can make some adjustments all at once, based on what's written here:

http://www.yoctoproject.org/docs/current/dev-manual/dev-manual.html#testing-packages-with-ptest

  toward the end of that section, there is the claim:

"However, you still must add a do_compile_ptest function to build the
test suite. Add a function similar to the following to your recipe:

     do_compile_ptest() {
        oe_runmake buildtest-TESTS
     }


  well, not really ... i did some perusing and there are numerous
ptest-enabled recipes that don't define their own do_compile_ptest()
routine, obviously because the standard compile step handles the
compilation of the test code.

  and, finally, there's this last claim:

"The ptest class automatically copies the file run-ptest to the target
and then runs make install-ptest to run the tests. If this is not
enough, you need to create a do_install_ptest function and make sure
it gets called after the "make install-ptest" completes."

  couple things there. rather than define a do_install_ptest()
routine, i notice a number of recipes simply patch their Makefile to
add the appropriate install-ptest: target, so if one is clever enough
to write the proper Makefile target, one could have a ptest-enabled
recipe with no definition whatsoever of *any* of the do_*_ptest()
routines.

  oh, and about that last claim:

"If this is not enough, you need to create a do_install_ptest function
and make sure it gets called after the "make install-ptest"
completes."

  don't know what you mean by "make sure it gets called ..." since the
code in ptest.bbclass:

        if grep -q install-ptest: Makefile; then
            oe_runmake DESTDIR=${D}${PTEST_PATH} install-ptest
        fi
        do_install_ptest

pretty much guarantees that it will be called -- there is no need for
the developer to "make sure" of it, yes?

  anyway, i think i have a handle on this. any thoughts on the above?
