I read @try/@catch as part of the same construct, just like if/else. According
to the style we’re supposed to use, the @catch should be moved up to be nestled
between the } @braces {.

Done.

Reword? It’s not really validating OCMock, it’s validating what you asked OCMock
to do.

I'm not liking this choice better, do you have a suggestion here?

This also struck me as a bit off, but I didn't leave a comment. How about
'verifying' instead of 'validating'? Maybe "Failed to validate OCMock: "?
