Hi,
We don't provide any support or have any experience with CppUTest so unfortunately i cannot be of much help here. There are certainly eclipse plugins available like the Eclipse plugin for CppUTest unit test harness, again though I don't have any experience with using this and its worth noting that this wont have any insight into CCES.
All I can recommend is the Third Party product (TESSY) that I mentioned previously.
Regards,
Colin.
