Integrating with JMock

One minute tutorial

Create a Behaviour Class that extends UsingJMock from the jmock extension library. UsingJMock brings together a bunch of “sugar” methods for use when creating/setting up mocks and expectations. It also provides auto-verification for all mocks.

You use jMock like so:


   public class CheeseBehaviour extends UsingJMock {
       public void shouldRequireTheUseOfMocks() {
           // given
           Mock cheese = new Mock(Cheese.class);
           Sheep sheep = new Sheep((Cheese)cheese.proxy());

           //expect
           cheese.expects(once()).method("squelch").withAnyArguments();

           // when
           sheep.eatCheese();

           // then
           verify();
       }
   }

 

You then run your behaviour like so:
java -cp org.jbehave.jar;jmock.jar;your_classpath SheepBehaviour
