hi All,

I am Manoj Keshavaprakash. I am new to model based development, I have created a small ecore metamodel(class diagram) using the graphical editor. Now I want to run some custom test cases to change the attribute values of the model. I tried using the .genmodel to create the automated test. But these test are not very helpful for me.

I request in this forum to guide to write my own test case to change the values of my attributes.

I have attached a file with the description of the problem for your reference.

Regards,
Manoj

You have to change the value through the Java API, either the generated one (if you generated the code from the genmodel) then you should have a "setNoOfSeat(int i)" in the "Booking" Java class, or reflectively by getting the EObject instance and then calling the .eSet().

From your question it looks like you are quite new to the EMF technology, you might find the following tutorials interesting:

Thank you for your clarification. Now am able to get things working. But now I have a small question:

I have a metamodel (.ecore file (class diagram)) created using the graphical editor. Now I am able to create the dynamic instances programmatically, but in my metamodel I have a composition (Containment reference) wherein i want to create child instance of the contained class (programmatically). Please find the attached metamodel and related images for reference.
