Subject: [PATCH 2/3] kunit: tool: unit tests all check parser errors,
 standardize formatting a bit
From:   Daniel Latypov <dlatypov@google.com>
To:     brendanhiggins@google.com, davidgow@google.com
Cc:     rmoar@google.com, linux-kernel@vger.kernel.org,

Precedence: bulk

Let's verify that the parser isn't reporting any errors for valid
inputs.

This change also
* does result.status checking on one line
* makes sure we consistently do it outside of the `with` block
