Testing the emf commands on a command stack? [message #427684]

Hello
Does anyone know how to make JUnit 4 tests on a command stack ?

I have a diagram generated through GMF and an EMF model
I want to make a JUnit test of the updates performed on model elements:
Create a command that will remove or add elements in a container?

In my case i have one model where an element can have two views:
1) it can be a Daigram-view
2) or a Node-view in another diagram

All the time I have to operate on the Semantic Model because this one
element is represented in 2 different Diagrams

As i have a SharedEditingDomain as proposed by itemis i do not get the
synchronization problems. But it means i have to traverse the model my
self and think of dependencies in the model myself

The model is complex and there are many cross references

I want to study how to modify the model in a right order but don't know
how to send commands around in JUnit

Does anyone have a simple example showing how to instantiate the
required environment (editor?) such that i can create my model objects
and send commands for change?

Best regards

Surayya

Surayya,

We have org.eclipse.emf.tests.edit which has tests for commands.
They're available as a zip with the downloads.
