We have a simple Quarkus project implementing an n-tier architecture. We would like to test the API using Rest Assured, by mocking the Repository layer.
@QuarkusTest
class ContactResourceTest {
@InjectMock
private ThirdPartyPanacheRepository thirdPartyRepository;
@Test
void doTest() throws BusinessException {
given()
.contentType(MediaType.APPLICATION_JSON)
.body(new MyDTO())
.when()
.post("/my/route")
.then()
.statusCode(200);
}
}
The exception I get is:

I also tried without using @InjectMock, instead using QuarkusMock.installMockForType in a @BeforeAll method, as documented here. This fails at the moment when the business code attempts to call a method on the repository, with the following error:
org.jboss.resteasy.spi.UnhandledException: java.lang.ClassCastException: class org.mockito.codegen.ThirdPartyRepository$MockitoMock$1469313994 cannot be cast to class com.company.repository.ThirdPartyPanacheRepository (org.mockito.codegen.ThirdPartyRepository$MockitoMock$1469313994 is in unnamed module of loader net.bytebuddy.dynamic.loading.MultipleParentClassLoader @7836c79; com.company.repository.ThirdPartyPanacheRepository is in unnamed module of loader io.quarkus.bootstrap.classloading.QuarkusClassLoader @7072bc39)
How can I install a mock for my test?
