[gpsd-dev] Test coverage

[Christian Gagneraud]

Hi,

Today, I gave a try to gcov and lcov, and the results are encouraging I 
think, this is what I've done:
- 1 coverage report per testsuite run
- 1 coverage report with all the runs

The results when run on a x86 machine can be found here:

This is experimental stuff, I'm sure there's some problems here and there.

For the "all" testsuite, I think it is possible to merge all the 
testcases belonging to each other testsuite into a corresponding single 
testcase.
Attached is the diff to SConstruct. After banging my head against the 
wall, I stopped trying to find a nice way to add conditionally 
"--coverage", to LDFLAGS, CFLAGS and CCFLAGS, and went for a less subtle 
one...
I had to change the calls to mktemp as it was complaining about not 
having enough X ...
As well, the coveraging calls is unconditional, this is still 
experimental, thought.

Any comments welcome!

Chris
