Right now ComponentTestUtils hardcoded relies on MockComponentProvider. As soon as you e.g. want to use a GuiceComponentProvider you cannot use it any longer.

Proposal how to do that (by tmattsson):
@RunWith(MagnoliaPicoRunner.class)
public class ExampleGuiceTest {

@ConfigureComponents
public void configureComponents(GuiceComponentProvider provider)

{ ModuleRegistry moduleRegistry = mock(ModuleRegistry.class); when(moduleRegistry.getModuleNames()).thenReturn(new HashSet<String>()); provider.registerInstance(ModuleRegistry.class, moduleRegistry); }

@Inject
private ModuleRegistry moduleRegistry;

@Test
public void testSomething()

{ assertTrue(moduleRegistry.getModuleNames().isEmpty()); }

}
