Automagically Creating Mocks, States & Sequences

If you define fields to hold mock objects, states or sequences , jMock can automagically instantiate them, reducing boilerplate code.

To automagically create a mock object, annotate the field with @Mock. JMock will initialise the field to hold a new mock object with the same name as the field before the test runs.

For example, the following declarations create two mock objects named "cheddar" and "jarlsberg".

@Mock Cheese cheddar;
@Mock Cheese jarlsberg;

To automagically create State¹ and Sequence² objects, annotate the fields with @Auto. Again, jMock will initialise the field with a new object named after the field before the test runs:

@Auto States pen;
@Auto Sequence events;
