Hi,
I teste my DSL but take an error from unit testing genareted language. 
my xtend class is below :
package org.eclipse.xtext.example.domainmodel.tests
import org.eclipse.xtext.junit4.XtextRunner
import org.eclipse.xtext.example.domainmodel.DomainmodelInjectorProvider
import org.eclipse.xtext.junit4.util.ParseHelper
import static org.junit.Assert.*
import org.eclipse.xtext.example.domainmodel.Domainmodel
import org.eclipse.xtext.example.domainmodel.Entity
import org.eclipse.xtext.junit4.InjectWith
import org.junit.Test
import org.junit.runner.RunWith
import com.google.inject.Inject
@InjectWith(typeof(DomainmodelInjectorProvider))
@RunWith(typeof(XtextRunner))
class ParserTest {
@Inject
ParseHelper<Domainmodel> parser
@Test
def void parseDomainmodel() {
val model = parser.parse(
"entity MyEntity {
parent: MyEntity
}")
val entity = model.elements.head as Entity
assertSame(entity, entity.features.head.type)
}
}
Also,when ı create xtext project ,my project name is org.eclipse.xtext.example.domainmodel,language name is org.eclipse.xtext.example.Domainmodel,extension is dmodel.And then ı write grammar and ı generate language artifacts,consited org.eclipse.xtext.example under the org.eclipse.xtext.example.domainmodel.tests .these generated org.eclipse.example package consist DomainmodelInjectorProvider.java that ı used test class.So that,generated org.eclipse.xtext.example refactor org.eclipse.xtext.example.domainmodel manually,(if ı refactor this package name,ı take other error:( So the error can be encountered in current?

Did you try to debug the test? Can you post a stacktrace?
Regards,
Sebastian
