How to test an implementation of a homomorphic scheme?
The best work I know on "How to test an implementation of a fully homomorphic scheme" is the work from Tancrede Lepoint and Michael Naehrig. The article has been published at AFRICACRYPT 2014. Basically, you need to compare the efficiency (in space and time) of the most important operations: KeyGen, Encrypt, Add, Mult, Decrypt.
