From: Sam Spilsbury Date: Fri, 13 Sep 2013 02:01:20 +0000 (+0800) Subject: Add support for table-driven testing. X-Git-Tag: 1.2.91~32 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b502126e1943e7991fd54fe0190f80bb86264370;p=platform%2Fupstream%2Fweston.git Add support for table-driven testing. The new TEST_P macro takes a function name and a "data" argument to point to an arbitrary array of known size of test data. This allows multiple tests to be run with different datasets. The array is stored as a void * but advanced by a known size on each iteration. The data for each invocation of the test is provided as a "data" argument, it is the responsibility of the test to cast it to something sensible. Also fixed single-test running to only run the tests specified --- diff --git a/tests/weston-test-runner.c b/tests/weston-test-runner.c index ed5baf0..4274b39 100644 --- a/tests/weston-test-runner.c +++ b/tests/weston-test-runner.c @@ -47,9 +47,9 @@ find_test(const char *name) } static void -run_test(const struct weston_test *t) +run_test(const struct weston_test *t, void *data) { - t->run();
