Hmm, would need to re-write the linker to query the property every time when linking, instead of initializing it once when the class is initialized. (I don't think it's possible to run tests in different forks with just TestNG). Seems like using a separate test file is more straight-forward? Maybe I'm misunderstanding but the result seems more or less the same.
