A noble cause, but since multiple options are being tested for multiple
controllers in the same file, once you have all the proper checks in
place the tests won't actually be verifying all of the negative tests -
only the first failure will be noticed - if one of the others is missed,
it won't "fail extra hard" or anything.

Although I hate to explode the number of tests, I think if you want to
have proper negative testing for every options that doesn't belong on a
particular controller, then you'll need a separate test case for each
combination of option and controller model. And since that would make
for a *lot* of test cases if we tried to extrapolate to all other
options for all other elements, I don't know that it's worth going down
that rabbit hole.

(What we really need is a more intelligent test rig that would allow
specifying a single test with a list of variations/diffs and a note of
whether the test should succeed or fail with that difference. It would
end up taking the same amount of time to run the tests, but at least the
amount of xml would be drastically reduced.)
