Unit tests are not working or missing

[dacb]

I couldn’t find the unit tests or testing framework or they are failing and not working for me. If you don’t have any, then make sure you justify this decision somewhere, maybe the README.md. I’m skeptical that any bit of code doesn’t need unit tests.

Yes we have the unittest intergrated through travis CI(test folder under mss folder), but it is now failing for building so we still under working, we are definitely going to make sure it works.
