Additionally, this This question might be a misunderstanding of the intent of some of the terminology in the above paragraph, so this is mostly a request for clarification. With my pre-conception of what unit tests are, I read "test a single unit of code" to mean a relatively narrow piece of a subsystem. So if I understand correctly, taking examples from patch 17 "of: unittest: migrate tests to run on KUnit", each function call like KUNIT_ASSERT_NOT_ERR_OR_NULL(), KUNIT_EXPECT_STREQ_MSG(), and KUNIT_EXPECT_EQ_MSG() are each a separate unit test, and thus the paragraph says that each of these function calls should have no dependencies outside the test. Do I understand that correctly? < snip > -Frank _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
