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

[Sergey Boyko <sboyko@xxxxxxxxxxx>]

Hi Emmanuel,

QVTO build provides a number of unit-tests which proceed exactly as you 
described.
Look at 
org.eclipse.m2m/org.eclipse.m2m.qvt.oml/tests/org.eclipse.m2m.tests.qvt.oml 
plugin. There's TransformTests.interpreterSuite() suite that accumulates 
 unit-tests with that execution sequence. Script files (.qvto), input 
and output models is located under parserTestData/models folder.

For output models comparison we use our own engine (package 
org.eclipse.m2m.tests.qvt.oml.api.framework.comparator.*) that 
implements algorithm for calculating Selkow's distance of two
trees.

Regards,
  Sergey
