I really don't have any informed opinion on this. I can see arguments both ways... putting all you eggs in one basket can be seen alternately as foolhardy or highly efficient :)

FWIW in the past I've had problems with trying to combine multiples tests that generate errors into one file. The compiler seems to like to bail out early when it sees errors. I guess that experience was working subconsciously.

Of course that doesn't apply here as these are all warnings. And a bunch of separate files make the test run slower.

So I agree with you - I'll consolidate them.
