The thread safety analysis requires a bit of setup, that's why we tend to keep the tests in one file. I'll admit that the C++ tests have grown quite large, but for ObjC++ it's still very manageable.

On one hand, the all-in-one test files get to be unwieldy size, but on the other hand, it's nice having everything integrated into a single file for testing purposes. I'd say go with the all-in-one approach because it's consistent with how we otherwise test thread safety and there are some (albeit, minor) benefits.
