[jira] [Updated] (DELTASPIKE-707) AbstractMockManager does not support interfaces mocked by mockito

["Falko Modler (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/DELTASPIKE-707?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Falko Modler updated DELTASPIKE-707:
------------------------------------
    Description: 
Following the [manual|https://deltaspike.apache.org/test-control.html#mock-frameworks], I tried to mock {{EntitityManager}} in my test class:
{noformat}
@RunWith(CdiTestRunner.class)
public class SomeTest {

    @Inject
    private DynamicMockManager mockManager;

    @Test
    public void mockitoMockAsCdiBean() {
        mockManager.addMock(Mockito.mock(EntityManager.class));
        [...]
    }
}
{noformat}
Unfortunately this doesn't work as {{AbstractMockManager}} fails with:
{noformat}
java.lang.IllegalArgumentException: $javax.persistence.EntityManager$$EnhancerByMockitoWithCGLIB$$b065dd9c isn't a supported approach for mocking -> please extend from the original class.
	at org.apache.deltaspike.testcontrol.impl.mock.AbstractMockManager.addMock(AbstractMockManager.java:45)
{noformat}

Following (rather ugly) workaound fixes the problem:
{noformat}
    @Typed(EntityManager.class)
    public static abstract class EntityManagerMockBase implements EntityManager {
    }
{noformat}
{noformat}
mockManager.addMock(Mockito.mock(EntityManagerMockBase.class));
{noformat}

If this problem cannot be solved then the documentation should at least mention that mocking does not work for interfaces and how to work around that.
