kunit: test: add tests for KUnit managed resources

2019-09-30T23:35:01Z

Add unit tests for KUnit managed resources. KUnit managed resources (struct kunit_resource) are resources that are automatically cleaned up at the end of a KUnit test, similar to the concept of devm_* managed resources.

kunit: test: add the concept of assertions

2019-09-30T23:35:01Z

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.
