@Produces @Named gives WELD-001408

Question

I try to hug CDI and in this case annotations @Producesand@Named

I have the following code

@RunWith(CdiRunner.class)
public class cdiTest {

@Inject
protected CDIModel em;

@Test
public void injectionTest(){
    Assert.assertEquals("this", em.getMyString());
}

}

public class CDIModel {

String myString;

public CDIModel(String myString) {
    this.myString = myString;
}

public String getMyString() {
    return myString;
}
}

public class EntityProducer {

@Produces
@Named("this")
@Singleton
public CDIModel doThis() {
    return new CDIModel("this");
}

@Produces
@Named("that")
@Singleton
public CDIModel doThat() {
    return new CDIModel("that");
}

}

Why am i getting

org.jboss.weld.exceptions.DeploymentException: WELD-001408: Unsatisfied 
dependencies for type CDIModel with qualifiers @Named
  at injection point [UnbackedAnnotatedField] @Inject @Named protected 
persistence.dao.cdiTest.em
  at persistence.dao.cdiTest.em(cdiTest.java:0)

After adding @AdditionalClasses (EntityProducer.class) I get

org.jboss.weld.exceptions.DeploymentException: WELD-001409: Ambiguous 
dependencies for type CDIModel with qualifiers @Default
at injection point [UnbackedAnnotatedField] @Inject protected 
dk.nykredit.lanc.persistence.dao.cdiTest.em
at dk.nykredit.lanc.persistence.dao.cdiTest.em(cdiTest.java:0)
Possible dependencies: 
- Producer Method [CDIModel] with qualifiers [@Default @Named @Any] declared 
as [[BackedAnnotatedMethod] @Produces @Named @Singleton public 
persistence.dao.EntityProducer.doThat()],
- Producer Method [CDIModel] with qualifiers [@Default @Named @Any] declared 
as [[BackedAnnotatedMethod] @Produces @Named @Singleton public 
persistence.dao.EntityProducer.doThis()]

Answer 1

CDI-Unit does not scan all classes, so it does not knwo about the EntityProducerclass. Thus, you must manually add the classes / packages that you want to scan using CDI.

You can use annotation @AdditionalClasses:

@RunWith(CdiRunner.class)
@AdditionalClasses(EntityProducer.class)
public class cdiTest {
    ....
    ....

}

EDIT

Then you have an indefinite addiction because you did not correctly qualify your injection. You should use @Named("this")or @Named("that")in a test class:

@Inject
@Named("this") // or @Named("that")
protected CDIModel em;

, CDI @Qualifier @Named
