How to unit test global scoping [message #861118]

Hi,

for my local scope provider, I easily provided unit tests by building partial EMF-ASTs
and calling getScope(..) with the corresponding element.

For my global scope provider I want to do the same. However, i wonder how to put an IEObjectDescription onto the index programatically.

I'm looking forward to any ideas or hints.

Regards,
Felix

Hi,

do you do any customization to index? if not what about binding a complete mock for the test.

No, i don't do any customization to index.
How can i create the mock for the test?
I'm not familiar with the index and don't know, how to put an IEObject Descripton onto the index.

Hi,

you have basically two choices:
(1) use the std behaviour without any mocks => simply take care the eobjects that should be in the global scope
have to reside in the same resourceset as test object you test the scoping on.
(a) create a resourceset
(b) create a resource in the resourceset and add the objects in the global scope to it
(c) create a resource in the resourceset and add the test object there

(2) you bind a IGlobalScopeProvider in a special runtime module + setup you use in the test
the global scopeprovider returns a scope. use e.g. a simple scope

btw if you dont do any customizations to the global scope, why do you want to test it at all?

Well, I misunderstood you earlier, I do some changes to the index: I provide an own implementation of IDefaultResourceDescriptionStrategy (btw, why is there a Default in the interface name?) to handle which EObjects are exported.

When I do create a ResourceSet (with ResourceSetImpl) for the tests, how does the framework know of my own ResourceSet or does the creation of ResourceSetImpl take care of that?

A second thing is, i want to check that a declared entity is unique on the index. For that reason I inject my Validator with an instance of IResourceDescriptions (note the plural 's') and calling the "getExportedObjects(..)" method. Running the plugin, this works fine. However, running the tests, an exception is thrown when invoking that method. I guess it has something to do with the index and ResourceSet, too?

Thanks so far,
Felix

Hi,

in general the "index" works different standalone and in ui.
standalone it is resourcesetbased. in ui it is "container based" = project based.

please use an injector to create a ResourceSet.

How can I Inject a ResourceSet? Is IResourceSetProvider the correct class (but that is only available in the ui project and how to retrieve the IProject instance)?

Sorry, but I didn't find documentation for this kind of stuff.
