Mocks are most useful in isolated unit tests but can also be used in integration tests. Almost all methods can be stubbed in one of three basic ways. The jMock Scripting Extension lets you define custom actions inline in the expectation as BeanShell2scripts.
For example if you are exercising the code. Because a script is represented as a string it does not play well with refactoring tools. 15032016 I found myself in a similar situation wanting to check a field of an object passed into a mock.
Timeout in JMock Synchroniser Jun 1 st 2012 JMocks Synchroniser serialises access to the mock objects context it means all invocations of mocked methods call will be synchronized on the same monitor effectively forcing them to run in sequence without thread safety concerns. 03022011 With JMock you must specify all the invocations that occurs on the mock object.

The context mocks out the objects that the Publisher collaborates with in this case a Subscriber and checks that they are. Tests usually need to specify expectations with different cardinalities to allow some method calls to occur but not fail if they dont expect methods to be called more than once or not all or ignore mock objects that are not relevant.
That represents the context in which the Publisher exists. If you dont do it your test will fail. A Japanese recipe for cucumbers marinated in vinegar sugar salt and ginger.
