How to mock the produced bean

Hi everyone,

in my testcase I would like to Mockorg.apache.myfaces.extensions.cdi.core.api.resource.bundle.ResourceBundle (sothat I can return test connection strings instead of production-ones).My unittest is set-up to run withorg.apache.openejb.junit.ApplicationComposer and Mockito.


Testcase:

import org.mockito.Mock;
import org.apache.myfaces.extensions.cdi.core.api.resource.bundle.Bundle;

@RunWith(ApplicationComposer.class)
public class AzureSchedulerWorkerTest {
...
    @Mock
    @Bundle(SchedulerConfiguration.class)
    private transient ResourceBundle schedulerConfiguration;
...
    @MockInjector
    public Class<?> mockitoInjector() {
        return MockitoInjector.class;
    }

    @Module
    public Class<?>[] classes() {

return new Class<?>[] { ... ResourceBundle.class,ResourceBundleProducer.class, ... };

    }

    @Test
    public void testSomething() {
        ...
when(schedulerConfiguration.getValue(SchedulerConfiguration.StorageConnectionString.class)).thenReturn("UseDevelopmentStorage=true");
        ...
    }
}

Currently I receive following exception:

SEVERE: CDI Beans module deployment failed

org.apache.webbeans.exception.inject.DeploymentException:javax.enterprise.inject.AmbiguousResolutionException: Ambiguous resolution

My question is - why does this happen and how to fix it?

I am guessing the issue could be that @Mock uses own Producer (or othermagic) to do the injection and then there's ResourceBundleProducer. Thisassumption however does not explain the listed beans inAmbiguousException (I would expect two ambiguous producers).

I was thinking to @Specialize ResourceBundleProducer and control what isbeing produced but that's hell of a construct just to substitutebasically a property file.


Any comments or suggestions are greatly appreciated!
