built-in self tests.


The ltp doesn't contain kernel selftests, the kprobes in kernel samples 
directory just contain some easy test for kprobes.




I want to be sure that we aren't creating custom wrappers that will
need to be maintained
for a long time.


The maintaining work very little, because the kernel samples and kernel 
selftest's change were not constantly changing very much.




Comments/documentation in the script don't exist, so it is difficult
to look at this and
understand what it is actually trying to test. A header block and
comments before each
test are required.


Ok, I have complete it and will send V3.

All of the modprobes really should be checking for failure, I realize you are
doing some lsmod calls and checking those, but that isn't always the case
in this script.

2018-06-21 Thread Bruce Ashfield
My general comment still stands from v1, That I don't see a lot of
value in creating a
whole set of custom tests and wrappers just for ptest use.

i.e. ltp already has a lot of these covered. kprobes, as do the
built-in self tests.

I want to be sure that we aren't creating custom wrappers that will
need to be maintained
for a long time.

Comments/documentation in the script don't exist, so it is difficult
to look at this and
understand what it is actually trying to test. A header block and

if you want to substitute "-" to "_" here, using bash pattern 
substitution will be much easier

# i="xx-yy-zz-ff"
# echo ${i//-/_}
xx_yy_zz_ff

most ptest (but not all) result format are following the same rule

"[PASS|SKIP|FAIL]" : testname

look at here 
https://www.yoctoproject.org/docs/2.5/dev-manual/dev-manual.html#testing-packages-with-ptest


PS: unified test output matters for LAVA testparse patten.

only enable ptest for linux-yocto_4.14 is not good.

we can still have one copy of run-ptest for different kernel version, 
but we need to make it works for different kernel.


To be clear, for example, linux-yocto-4.14, you might have 10 test 
cases, while in linux-yocto-4.15, you might have 12 test cases


so run-ptest might be like

a) run whatever test case we have, and the first thing is the check 
whether the test case exists,  for example, if directory 
"samples/trace_printk" exists, run it, if not , do nothing
