MissingResourceException in a unit test with EMF commands [message #1638662]

Hi all,

I get a MissingResourceException when I run a JUnit test on code that creates a CreateChildCommand. The stack trace says:

java.util.MissingResourceException: The string resource '_UI_XYZ_abc_feature' could not be located
	at org.eclipse.emf.common.util.DelegatingResourceLocator.delegatedGetString(DelegatingResourceLocator.java:480)
	at org.eclipse.emf.common.util.DelegatingResourceLocator.getString(DelegatingResourceLocator.java:385)
	at org.eclipse.emf.common.util.DelegatingResourceLocator.getString(DelegatingResourceLocator.java:359)
	at org.eclipse.emf.edit.provider.ItemProviderAdapter.getFeatureText(ItemProviderAdapter.java:1965)
	at org.eclipse.emf.edit.provider.ItemProviderAdapter.getCreateChildText(ItemProviderAdapter.java:1775)
	at org.eclipse.emf.edit.command.CreateChildCommand.<init>(CreateChildCommand.java:214)
	at org.eclipse.emf.edit.provider.ItemProviderAdapter.createCreateChildCommand(ItemProviderAdapter.java:1310)
	at org.eclipse.emf.edit.provider.ItemProviderAdapter.createCreateChildCommand(ItemProviderAdapter.java:1294)
	at org.eclipse.emf.edit.provider.ItemProviderAdapter.createCommand(ItemProviderAdapter.java:1089)
	at org.eclipse.emf.edit.domain.AdapterFactoryEditingDomain.createCommand(AdapterFactoryEditingDomain.java:462)
	at org.eclipse.emf.edit.command.CreateChildCommand.create(CreateChildCommand.java:60)

Is there a way to make the resource available in a unit test environment?

I have seen a few discussions on this type of exception in this forum, but I could not find a solution that matches my case.

Thanks,
Uwe

Are you running this as a pure JUnit test case or as an Eclipse
Application Unit? (Not sure the exact choices in the menu right now.)

I'm running this as a pure JUnit test case. I could try to run it as a plug-in test, but if there is a solution for pure unit tests, I'd prefer that.

Uwe,

The problem is that at development time, only the contents of the bin
folder are on the classpath (for stand alone), so all the additional
things specified in the build.properties are not (yet) on the classpath.
When deployed as a bundle at development runtime, PDE's magic ensures
they're available nevertheless...

Thank you for your reply, Ed. It seems that the creation of a CreateChildCommand is not compatible with a unit test environment. This might explain why there is no unit test for the CreateChildCommand class in the EMF git repo.

I'll try another approach to test my code.
