From 76066f93f1df27657eb937b7c9c091e3a6abf4db Mon Sep 17 00:00:00 2001 From: Rae Moar Date: Tue, 25 Jul 2023 21:25:19 +0000 Subject: [PATCH] kunit: add tests for filtering attributes Add four tests to executor_test.c to test behavior of filtering attributes. - parse_filter_attr_test - to test the parsing of inputted filters - filter_attr_test - to test the filtering procedure on attributes - filter_attr_empty_test - to test the behavior when all tests are filtered out - filter_attr_skip_test - to test the configurable filter_action=skip option Reviewed-by: David Gow Signed-off-by: Rae Moar Signed-off-by: Shuah Khan --- lib/kunit/executor_test.c | 116 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 116 insertions(+) diff --git a/lib/kunit/executor_test.c b/lib/kunit/executor_test.c index d7ab069324b5..01280cb8d451 100644 --- a/lib/kunit/executor_test.c +++ b/lib/kunit/executor_test.c @@ -7,6 +7,7 @@ */ #include +#include static void kfree_at_end(struct kunit *test, const void *to_free);
