Any way, right now i'm fighting hard to get the test project "loaded".
My first step is simply to get the generator running, i have several choices:

- 2 use CommandLineFrontend
- 3 instantiate Project "manually" like TestApi::doBuildProject()
But i'm a bit overwhelmed by the amount of boiler plate i have to write!
