### Question:
ClasspathDefinitionRegistry implements DefinitionRegistry { public com.iris.capability.definition.CapabilityDefinition getCapability( String nameOrNamespace) { return delegate.getCapability(nameOrNamespace); } @Inject  ClasspathDefinitionRegistry(@Named("capability.file.dir") List<String> capabilityFileDir); static DefinitionRegistry instance(); com.iris.capability.definition.CapabilityDefinition getCapability(
         String nameOrNamespace); Collection<com.iris.capability.definition.CapabilityDefinition> getCapabilities(); ServiceDefinition getService(String nameOrNamespace); Collection<ServiceDefinition> getServices(); TypeDefinition getStruct(String name); Collection<TypeDefinition> getStructs(); EventDefinition getEvent(String name); com.iris.capability.definition.AttributeDefinition getAttribute(
         String name);  }### Answer:
@Test public void testGetCapability() { CapabilityDefinition person = registry.getCapability(PersonCapability.NAMESPACE); assertNotNull(person); assertEventExist(person, PersonCapability.InvitationPendingEvent.NAME); assertEventExist(person, PersonCapability.PinChangedEventEvent.NAME); assertEventExist(person, PersonCapability.PasswordChangedEvent.NAME); assertMethodExist(person, PersonCapability.DeleteLoginRequest.NAME); assertMethodExist(person, PersonCapability.GetSecurityAnswersRequest.NAME); assertAttributeExist(person, PersonCapability.ATTR_CONSENTOFFERSPROMOTIONS); assertAttributeExist(person, PersonCapability.ATTR_CURRPLACE); }
