Subject: tests: Add tests for LTTNG_UST_APP_PATH and LTTNG_UST_CTL_PATH
X-Git-Url: http://git.lttng.org./?a=commitdiff_plain;h=39c3cb7445a9505648730719aedcad602973cf1e;p=lttng-tools.git

tests: Add tests for LTTNG_UST_APP_PATH and LTTNG_UST_CTL_PATH

test_blocking_mode: Verifies that the sessiond starts (or doesn't start)
appropriately depending on the combination of path settings in
conjuction with `LTTNG_UST_ALLOW_BLOCKING` and `--blocking-timeout`.

test_path_separators:Path separators: Verifies the behaviour of the
sessiond and applications with multiple `LTTNG_UST_APP_PATH`s and
multiple `LTTNG_UST_CTL_PATHS`, including the verification of Java JUL
and Python agents.

test_ust_app_ctl_paths: Verifies the sessiond and traced applications
with different combinations of `LTTNG_UST_APP_PATH` and
`LTTNG_UST_CTL_PATH` settings.
