Probably just in its own file (we don't do a very good job of keeping a lot of related tests in a single file together - usually just add more files, it's not ideal but often hard to find other good groupings) - but if you're looking for related test files, try breaking the pass in some obvious way and see what tests fail - that should help you find some related tests that could be piggy backed on.
