Hi,
Background: I am building an ETL-grader which can automated assess the ETL script. I use EUnit to test if the ETL script generates the correct model.
Question: Now I want to compare the output model and the excepted model so that I can show the difference between them, when the test failed. How can I achieve this?
Best wishes,
Jian

Hi Jian,

This is already computed by EUnit, using EMF Compare - we simply do not save it anywhere at the moment. I will take a stab at a version that allows the EUnit Ant tasks to serialize the EMF Compare differences in XMI form, which you should be able to parse for your own reporting. Here is the Bugzilla issue, in case you would like to follow its development:

Best,
Antonio

I have pushed a first implementation of this to a new branch. I'll wait for our continuous integration process to validate it and a second read through the branch to merge it.
