unit test language with JavaVMTypes [message #754885]

Hello guys,

I am developing a grammar for a language based on Java.
I'm able to use the JavaVMTypes and can successfully run the editor with references to Java types. However when I run my language jUnit test, I get the following error:

org.eclipse.xtext.parser.ParseException: java.lang.IllegalStateException: Unresolved proxy 
h ttp://www.eclipse.org/xtext/common/JavaVMTypes#//JvmParameterizedTypeReference. Make sure the EPackage has been registered.
	at org.eclipse.xtext.parser.antlr.AbstractAntlrParser.doParse(AbstractAntlrParser.java:105)
	at .......

My setup configuration looks as follows:

    bean = StandaloneSetup {
        scanClassPath = true
        platformUri = "${runtimeProject}/.."
		registerGenModelFile = "platform:/resource/org.eclipse.xtext.xbase/model/Xbase.genmodel"
		registerGenModelFile = "platform:/resource/org.eclipse.xtext.common.types/model/JavaVMTypes.genmodel"
    }

Is there a special configuration required to allow JavaVMTypes to be visible to the jUnit tests? My generated editor however works correctly.

Thanks in advanced.

I am importing the JavaVMTypes as follows:

grammar org.xtext.java.AspectJ with org.eclipse.xtext.common.Terminals

generate aspectJ "h ttp://www.xtext.org/java/AspectJ"

import "h ttp://www.eclipse.org/emf/2002/Ecore" as ecore
import "h ttp://www.eclipse.org/xtext/common/JavaVMTypes" as jvmTypes
....

Hi,

how does your test class look like? this works for me

@RunWith(XtextRunner.class)
@InjectWith(MyDslInjectorProvider.class)
public class TheTest {
	
	@Inject
	private ParseHelper<Model> parseHelper;
	
	@Test
	public void test() throws Exception {
		Model model = parseHelper.parse("map string to java.lang.String");
		for (Mapping mapping : model.getMappings()) {
			System.out.println(mapping.getName() + " => " + 
mapping.getRef().getQualifiedName());
		}
	}

}

as well as this

public class Main {
	
	public static void main(String[] args) throws IOException {
		Injector i = new 
MyDslStandaloneSetup().createInjectorAndDoEMFRegistration();
		ResourceSet rs = i.getInstance(ResourceSet.class);
		Resource r = rs.getResource(URI.createURI("src/test.mydsl"), true);
		r.load(null);
		Model m = (Model) r.getContents().get(0);
		for (Mapping mapping : m.getMappings()) {
			System.out.println(mapping.getName() + " => " + 
mapping.getRef().getQualifiedName());
		}
	}

}

with

grammar org.xtext.example.mydsl.MyDsl with 
org.eclipse.xtext.common.Terminals

generate myDsl "http://www.xtext.org/example/mydsl/MyDsl"

import "http://www.eclipse.org/xtext/common/JavaVMTypes" as jvmTypes

Model:
	mappings+=Mapping*;
	
Mapping:
	'map' name=ID 'to' ref=[jvmTypes::JvmType|FQN];
	
FQN: ID ("." ID)*;

using Xtext 2.1.0 and a project created with the wizard.

Thanks for your reply Christian.

One of my unit tests looks as follows:

@org.junit.runner.RunWith(typeof(XtextRunner))
@InjectWith(typeof(AspectJInjectorProvider))
class MethodTest {
		
	@Inject ParseHelper<CompilationUnit> parser

	@Test
	def void stringMethodTest(){
		var model = parser.parse('''
			public aspect LineItemExposureControlAspect {
				public java.lang.String test() {
					java.lang.String result;
					return result;
				}
			}
		''')

		var aspect = (model.typeDefinitions.get(0) as AspectDeclaration).definition;
		var method = (aspect.body.members.get(0) as JavaMethodDefinition);

		Assert::assertEquals("java.lang.String",method.returnType.reference.type.qualifiedName); 
	}

}

However I noticed that the error only occurs when I run multiple tests immediately after each other.
I have quite a number of test cases and I run them by a simple right click on the test project choosing "Run as" -> "JUnit Test".
The error doesn't occur when I run the test individually.

Do you have any idea what causes this problem?
