Hi!
Some time ago I started to think about replacement for the current
runltp + ltp-pan test execution system, before I start writing any code
here are a few points that I currently have in mind. Feel free to
comment on them.
Here is what I think that is wrong with the current system:
* Open Posix Testsuite is not executed by runtest + ltp-pan
- technically this should be as easy as translating the return
codes and generating runtest files as we build the testsuite
* Current system doesn't support timeouts
- which should be easy to implement but would require change
to the runtest file format (one timeout for all doesn't
work as we have tests that runs less than second and tests
that takes more than ten minutes).
* The output to stdout is messy
What I would like is:
[004/243] getrusage04 .................................. [FAILED]
[005/243] getsid01 ..................................... [RUNNING]
* The new tool should be able search runtest files for particular test
names, blacklist some tests if needed, etc. Which is now done by
grepping runtest files in the hacked together runltp script.
* There are tests that needs a disk partition or loopback image, we
should handle that and export right environment variables. This should
be designed, documented and fixed.
* The current system doesn't produce usable logs
Well you get list of testcases that succeeded and list of testcases
that has failed, which is better than nothing.
But what I'm thinking about is some more structured format that
will include test output, possibly test duration and so. I personally
think that JSON is good candidate for this job as it's structured,
easy to read and widely supported as there are libraries for python,
perl, etc.
Then we could create git repo with reference results. Generate html
pages from the repo with results. Write scripts for result comparsion,
etc.
The JSON log may look like:
"LTP Version": 20130109,
"System Info": {
"Kernel Version": "3.7.1",
"Hardware": {
"Arch": "x86_64",
"CPUs": 2,
"Ram": 4051840,
(more filelds like this follows),
},
},
"Results": [
{
"Test Name": "getrusage04",
"Test Result": "FAILED",
"Test Runtime": 0.011532,
"Test CPU Time": 0.003234,
"Test Output": [
"TINFO : Using 1 as multiply factor for max increment",
"TINFO : utime: 0us; stime 0us",
"TINFO : utime: 0us; stime 4000us",
"TFAIL : stime increased > 2000us",
],
},
(more test results follows),
]
