Does using fail instead of fail-check work? It appears to, but that's
mostly a coincidence for this implementation. You can imagine a different
RackUnit implementation where this is not the case, so you should avoid it.
I think that mentioning define-check in the fail-check documentation is a
good idea, since they should be cooperating with each other. Note that define-check already mentions fail-check.
Thanks to @sschwarzer for letting me know my message was incorrectly processed by Discourse. I fixed the above reply. It appears Discourse will remove any content after a horizontal line when posted from email. Let’s see if this is true (sorry for a bit off-topic):
I read this, but I think mentioning that it's useful for stubs doesn't automatically say that this is the only use. So this is still a bit vague in my opinion.
