Quarkus Panache Mockito fails - mockito

Question

I struggle with mocking a Panache repository.
Here is the Entity:
import javax.persistence.*;
#Entity
public class Thing {
#Id
#GeneratedValue(strategy = GenerationType.IDENTITY)
#Column(name = "id", nullable = false)
private Long id;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
}
Simple repository:
import io.quarkus.hibernate.orm.panache.PanacheRepository;
import javax.enterprise.context.ApplicationScoped;
#ApplicationScoped
public class ThingRepository implements PanacheRepository<Thing> {
}
This is the resource:
import javax.inject.Inject;
import javax.ws.rs.Consumes;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import java.util.List;
#Path("/things")
#Produces(MediaType.APPLICATION_JSON)
#Consumes(MediaType.APPLICATION_JSON)
public class ThingResource {
#Inject
ThingRepository thingRepository;
#GET
public List<Thing> list() {
return thingRepository.listAll();
}
}
and a simple test where I try to mock the repository:
import io.quarkus.test.junit.QuarkusTest;
import io.quarkus.test.junit.mockito.InjectMock;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.mockito.Mockito;
import javax.inject.Inject;
import java.util.ArrayList;
import java.util.List;
import static org.junit.jupiter.api.Assertions.assertNotNull;
#QuarkusTest
class ThingResourceTest {
private Thing thing;
#Inject ThingResource thingResource;
#InjectMock ThingRepository thingRepository;
#BeforeEach
void setUp() {
Thing thing = new Thing();
thing.setId(1L);
}
#Test
void getAll() {
List<Thing> things = new ArrayList<Thing>();
things.add(thing);
Mockito.when(thingRepository.listAll()).thenReturn(things);
List<Thing> response = thingResource.list();
assertNotNull(response);
assertNotNull(response.get(0));
}
}
The test fails because the response list is <null>.
The debugger tells me the thingRepository is actually mocked. But for some reason Mockito.when().thenReturns() does not return the list I set up.
What am I missing?
Thank you for any help.

Answer 1

I had the thing double declared. One time as class variable, and again in setUp(). Bummer. I apologize for the noise.
