Thanks for your reply.

I think you answer has pointed me in the right direction: I am trying to test for the wrong thing. I should be testing (perhaps via a mock object or similar), that my function does not do anything expensive (e.g., call a database function) to return a result when called in void context. I was erroneously focusing on the return result, rather than the operations of my function. Testing the return value (or lack thereof) would not prove if my function was performing a pointless operation.

Thanks!
