Class InMemoryNcFake

java.lang.Object

alma.acs.nc.testsupport.InMemoryNcFake

public class InMemoryNcFake
extends java.lang.Object

This class provides a simple in-memory notification mechanism that tries to mimic a corba notification channel, without the need for ACS services to run.

It should be used only to simplify unit test setups, and never in an operational environment.

Unit tests may use this class in two ways:

• Explicitly: The test can instantiate InMemoryNcFake and create the publisher and subscriber objects from there. This will work fine if the classes under test are designed to get the supplier/subscriber objects injected, rather than retrieving them directly from the container services.
• Implicitly: The test can wrap the container services (e.g. by extending jcont :: ContainerServicesProxy) so that methods ContainerServicesBase.createNotificationChannelPublisher(String, Class) and ContainerServicesBase.createNotificationChannelSubscriber(String, Class) are overridden and use this InMemoryNcFake class. This should work also for cases where the container services get passed around the code, and deep down in some class under test the suppliers / subscribers are created.

In either case, the resulting supplier and subscriber objects will have the same interfaces as their real NC variants. See also http://jira.alma.cl/browse/COMP-2890 about such tests.
