Test improvement

[AlessandroMinoccheri]

Hello everybody,
I would like to cover all the repository with tests.

What do you think top open a Pull request on WIP and split It into different task for every class for example?

It could be interest to integrate travis for CI or some similar tool to do It

Let me know

I think we'll need @davidedonattini help here. Our accounts have not enough rights access to add this project to travis CI.
