[news.eclipse.modeling.m2m] Re: [QVTO] Unit testing

["Emmanuel.Leguy" <Emmanuel.Leguy@xxxxxxx>]

Thank you very much Sergey. The plugin helps me to understanding a 
little more the qvto architecture (is there some docs?). I think the 
qvto transformations are only able to run in a plugin context. Am i right?
I would like to know if there is a solution to make a 'stand alone' (not 
a plugin) java application using the qvto api which run transfos and 
unit-tests?
I think i understand how to launch a transfo and test the result. It is 
what the plugin does. But i want to test each mapping separatly. How can 
i just run a mapping or a set of mappings from a transfo?

Another question:

Does qvto store compiled transfos into files? So that, i could run 
transfos directly from the compiled version.

Thank you,

Manu.
