Subject: Add tests of concurrent prepare_app and app_install/uninstall
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=cec976e0bb9f9efe46331f55bb4820163332eb75;p=platform%2Fcore%2Ftest%2Fsecurity-tests.git

Add tests of concurrent prepare_app and app_install/uninstall

These tests should properly stress the two-threads implementation
of the daemon that has dedicated thread just for prepare_app call.

The test takes more time so its run as RUNNER_TEST (not CHILD test)
as CHILD tests do  have a timeout in the testing framework internals.
