Hi,

I'm trying to start writing tests for my DSL.
I started having a look at the org.eclipse.xtext.example.domainmodel.tests example to see how to write JUnit tests mainly for the grammar and the validator.

I decided to modify a little bit the DomainmodelJavaValidator to make it look likes mine. However, when I added

@Inject IResourceSetProvider resourceSetProvider;

into the DomainmodelJavaValidator

the Junit tests stopped being executed and I got the following exception

com.google.inject.CreationException: Guice creation errors:

1) No implementation for org.eclipse.xtext.ui.resource.IResourceSetProvider was bound.
while locating org.eclipse.xtext.ui.resource.IResourceSetProvider

Any ideas way injecting the IResourceSetProvider into the Validator breaks the JUnit tests?
Thanks!

Hi iresourcesetprovider is a ui component not a standalone component

Is there any way to keep the iresourcesetprovider in the validator and testing with Xtend JUnit?
I'd like to avoid removing iresourcesetprovider from the validator.

What about running ui Tests? What are you doing with the provider in
the validator. Of course you could bind a special impl for the tests
as well. But the solution depends on why you need the provider

I use the iresourcesetprovider in the validator to resolve a proxy. Such provider allows me to retrieve the second parameter required by EcoreUtil2.resolve

EcoreUtil2.resolve(EObject proxy, ResourceSet resourceset);

HI,

a Provider<ResourceSet> does the very same.
but: where does this eobject come from.
it is not ususal to explicitely resolve things in validators

HI,
Thanks for the tip. It works fine!
The reason why I resolve things in the validator is because the information convey by the IEObjectDescription is not sufficient to make a decision.
I believe (can you confirm, please this) that the best solution would be to enrich the IEObjectDescriptiondata with the required data as suggested in

https://www.eclipse.org/forums/index.php/m/1053596/#msg_1053596

but I haven't succeeded so far to do that (tips and pointers on that would be more than welcome).

Hi

You can pass additional information in the eAdapter on the EObject,.
which is the workaround I use for
