Questions about compiling test.cpp and output of index.js

I'm running these code on Linux ubuntu 16.04.

First, my index.js works well but I didn't find the output of using libsnark（like the detailed time and the mark of entering a new process.）I'd like to know how to get the corresponding output.

Second, I find test.cpp in the project，it wasn't compiled，so I add it in makefile and get errors. I find that some functions in test.cpp didn't even exist. So I want to know, how can I get the test.cpp works well ? （Maybe the test.hpp is left for me to write the nonexistent corresponding funtion？）
