Some code in these tests is not intended to be executed, but rather to detect compiler warnings. Instead of having an obscure fatal error if this code is run in a debug build, it now has a clear fatal error if run in any build. Change-Id: I1c9d27bb14ebf3313865b68e3e57668ba1d14e25 Task-number: QTBUG-17582 Reviewed-by: Rohan McGovern (cherry picked from commit 70f42ced8e01ddf0098b143e5804c22d55ebf16f)
