Need to run JUnit plug-in test with no GUI [message #1803474] Fri, 01 March 2019 10:55 Go to next message

Hello everybody,

I'm working on a JUnit plug-in test that loads a model (org.eclipse.uml2.uml.Model) to perform some operations.

To retrieve the model I use the following rules:

@Rule
public final PapyrusEditorFixture editor = new PapyrusEditorFixture();


@Test
@PluginResource("resources/xxx.di")


And in the method I use:

editor.getModel();


In the run configuration, I checked 'run a product: org.eclipse.platform.ide'.

The problem is that each time I run the test, the GUI of papyrus appears.

It there a way to perform a JUnit plug-in test that loads a model without the need to open the GUI of Papyrus?

In the run configuration, if I select 'run an application: Headless Mode', I get the following exception:
java.lang.IllegalStateException: Workbench has not been created yet.


Many thanks,
Alberto

Hi, Alberto,

There are other kinds of AbstractModelFixture that you can use in headless tests. Search for references to ModelSetFixture and ServiceRegistryModelSetFixture, in particular, for examples of their use.

HTH,

Christian

Hi Alberto,

It's not possible to run the "Papyrus Editor" headless, since it is by definition a UI Component. However, it is possible to load a Papyrus Model headless (Not with the PapyrusEditorFixture though)

Check org.eclipse.papyrus.junit.utils.rules.ModelSetFixture or org.eclipse.papyrus.infra.emf.readonly.ReadOnlyManagerTest

HTH,
Camille

Using the ResourceSetFixture the test works in Headless Mode.

Thanks Christian and Camille!
