Sorry, I thought I addressed that in the next section, specifically by calling out: printing the test plan, and adding the new kernel command line option.

Yeah, that's reasonable. I am not sure where I should put this in the documentation, however. This seems kind of a technical detail, and all the pages I have now are more of how-tos, I think. Maybe I should send a patch which adds a page detailing how KUnit works? I would like to get some other people's thoughts on this. Such a technical guide wouldn't provide me a lot of value, at least not now, so I want to make sure that something like that would be valuable to others.
