Hi All,
Some people have asked how the code coverage for udev looked. I ran
gcov for udev on all the tests in udev/test/ and received the following
results (which are enclosed below and also at the link listed):

Thanks,

Hi,
How about your coverage for the whole udev project? I have got a coverage
data 86.8% for the whole project by our test suite. How do you think of this
result?
In addition, there is no coverage data for udevd.c, you can test it using
test/udevd/udevd-test.pl in udev-025 or later version:-)
Thanks!
Nick

Hi Nick,
I do not have a test suite for the whole udev project and thus have no
results to compare with yours :( I was only reporting on the results of
the tests provided by udev. I have rerun gcov for udev for all the udev
tests including udev/test/udevd/udevd-test.pl and enclosed the results
below (link also provided). Greg, would you be interested in patches to
expand/add some udev tests to hit the untouched portions of code or are
you satisfied with the current coverage provided by udev/test/? Thanks,
Leann

Code coverage reports by themselves don't really mean anything. But if
you have real, useful tests that exercise the functionality of the code,
instead of just trying for complete coverage, that's useful.
So yes, I'm always interested in adding more tests to the test script to
try to exercise more functions in udev, mainly to make sure we don't
break anything in the future, and to validate that everything works
today (much like your last patches did.)
thanks,

Leann,
In facat, to the best of my knowledge there is a tool called LTP which can
total the coverage data for the whole project.

Greg,
I will try to work out some test scripts for udevinfo, udevstart, udevtest
binaries when i have more time. In fact there have been some test scripts
for these binaries in our inner test but those are not so good to put them
into source tree. I will improve them and then submit them to you.
Nick
