From e4aea8f8532b55f966d828efcf720f8aeb203e13 Mon Sep 17 00:00:00 2001 From: Brendan Higgins Date: Mon, 23 Sep 2019 02:02:41 -0700 Subject: kunit: test: add the concept of assertions Add support for assertions which are like expectations except the test terminates if the assertion is not satisfied. The idea with assertions is that you use them to state all the preconditions for your test. Logically speaking, these are the premises of the test case, so if a premise isn't true, there is no point in continuing the test case because there are no conclusions that can be drawn without the premises. Whereas, the expectation is the thing you are trying to prove. It is not used universally in x-unit style test frameworks, but I really like it as a convention. You could still express the idea of a premise using the above idiom, but I think KUNIT_ASSERT_* states the intended idea perfectly.
