Hi Caike,
Can you open an issue for this milestone?
You are right, the "tests" folder is not running on the build path as it should and on the way I also found out that the ThrowError request handler has a bug too. I will start working on it right now, fixing the bugs that are there, running it by hand, as soon as it is fixed I can fix the scripts.
If both the rake spec and (cd full-examples/restfulie-restbuy && rails server && rake spec) works fine, you can assume the change is good so far.
Regards
