Tests are broken

[Raffo]

Currently if we run the tests for generation, those don't pass.

I started some time ago to try to fix them, you can find a diff https://github.com/devimteam/microgen/compare/master...Raffo:master that explains what I was trying to do.

I stopped cause I think that the strategy of going with string comparison with the generated files is very fragile and it can break anytime (it does actually).

I also suggest to add a travisCI or circleCI build such that we can make sure that tests are actually passing.
