Hello Everyone,

I am really new to Epsilon and am a bit lost.I am not very familiar with testing either. Could anyone please tell me how I can test my model transformation? Lets say, I have two meta models, M1 and M2 and a transformation in ETL from M1 to M2. I have a file where I have an model that conforms to M1. Now, I want to input this file to the ETL application that I have written and I want to see the output file that I get.

Could someone kindly guide me in this process?

I will really appreciate some help.

Thank you so much and looking forward to hearing from someone Smile

Best regards,
Chandrakana.

Hi Dimitris,

However, I have another question now. I have written a transformation and also a JUnit test to check if the transformation works for a simple hello-world model. I have the helloworld code conforming to the input meta-model and I also know the output code that I expect from my transformation. However, in the tutorial it shows that in a source folder named model, they have stored the tree.model and graph-expected.model files.

Could you please tell me how I can generate the .model files? What I mean is, if I have a file that conforms to an xml meta-model and I want to generate a file conforming to some model X (say), then how will I get the .model file from the .xml file?

Thank you so much,
Best,
Chandrakana.

Hi Dimitris,

Could you please take a look at my last question? I am not able to understand how I can get the models conforming to my metamodel Sad

Basically, I have codes in text format that conform to the metamodels that I am dealing with. In this case, how can I test my transformation?

Thank you so much in advance,
Best,
Chandrakana
