Hi @igalic,

sorry for the delay. I added spec tests.

Could you have a look into what I've done? I'm quite new to rspec, so it may be not correct.

Also...for information the travis tests seems to be failing for everyone, it's not related to this PR.

i say we merge this, and see what happens

[Augustin-FL]

@igalic do you have merge rights on this repo?

(as explained above, the tests are failing for everyone, it's not related to this PR)

the next release (v0.3.0) is already quite big. I will release this now, then merge this PR and do a new release. In case this breaks something, people can still use v0.3.0. thanks for all the work!
