Subject: Re: [PATCH v13 09/18] kunit: test: add support for test abort

Quoting Brendan Higgins (2019-08-13 22:50:59)
> Add support for aborting/bailing out of test cases, which is needed for
> implementing assertions.
> 
> An assertion is like an expectation, but bails out of the test case
> early if the assertion is not met. 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.
