How to understand test.py?

[jiabinpeng]

Hi @dgriff777 , thanks for your code firstly. I am learning your code https://github.com/dgriff777/a3c_continuous. And when I learning the test.py, I don't understand this file's function. In addition, why put the test function into Process firstly? What I mean is that "p = mp.Process(target=test, args=(-1, args, shared_model))". Could you give some guidance? Thanks
