[lttng-dev] Running lttng-tools tests?

[Thibault, Daniel]

After installing lttng-tools (2.2.0-rc2) in /usr/src, I tried this:

$ cd /usr/src/lttng-tools-2.2.0-rc2/tests
$  ./run.sh unit_tests

   And I got this:

unit/test_kernel_data .............. Dubious, test returned 1 (wstat 256, 0x100)
No subtests run 
unit/test_session .................. Dubious, test returned 1 (wstat 256, 0x100)
No subtests run 
unit/test_uri ...................... Dubious, test returned 1 (wstat 256, 0x100)
No subtests run 
unit/test_ust_data ................. Dubious, test returned 1 (wstat 256, 0x100)
No subtests run 
unit/test_utils_parse_size_suffix .. Dubious, test returned 1 (wstat 256, 0x100)
No subtests run

Files=5, Tests=0,  0 wallclock secs ( 0.03 usr  0.00 sys +  0.04 cusr  0.04 csys =  0.11 CPU)
Result: FAIL

   There is no README in lttng-tools/tests (unlike lttng-ust, but sadly like userspace-rcu), and the script is laconic, so I can't be sure if this is a true failure (my installation works) or if I just ran the tests wrong.  For userspace-rcu, I ran ' ./runtests.sh 2 2 10', but I got no PASS/FAIL evaluation so I'm not 100% sure the tests were a success.

   How are these tests supposed to be run?
