    package groovy.mock.interceptor
  
  
    The groovy.mock.interceptor is an all-groovy mock testing library.
    Terms:
    
        Collaborator
        An ordinary Groovy or Java class that's instance or class methods
        are to be called. Calling them can be time consuming or produce side effects that
        are unwanted when testing (e.g. database operations). 

        Caller
        A Groovy Object that calls methods on the Collaborator, i.e.
        collaborates with it.

        Mock
        An object that can be used to augment the Collaborator.
        Method calls to the Collaborator will be handled by the Mock, showing a demanded
        behavior. Method calls are expected to occur strictly in the demanded
        sequence with a given range of cardinality. The use of a Mock implicitly
        ends with verifying the expectations.
        

        Stub
        Much like a Mock but the expectation about sequences of method calls on the Collaborator is
        loose, i.e. calls may occur out of the demanded order as long as the ranges
        of cardinality are met. The use of a Stub does not end with an implicit
        verification since the stubbing effect is typically asserted on the Caller.
        An explicit call to verify can be issued to assert all demanded method call
        have been effected with the specified cardinality.
    

    Features:
    
        typical mock style of failing early
        mocks instance and class methods
        mocks final methods and final Collaborators
        mocks Groovy and Java Collaborators (but Caller must be groovy)
        can mock all objects of a given class (or a single Groovy object)
        mocks even if Collaborator cannot be injected into the Caller
        mocks even if Collaborator is not accessible on the Caller (no getter)
        demanded calls specified via recording calls on the Demand object (EasyMock style).
        cardinality specified as Ranges, default is 1..1; 'optional' can be achieved with 0..1
        behavior specified via Closures, allowing static or calculated return values, throwing exceptions,
            asserting argument values, etc. (even tricky sequence constraints
            by sharing state in the testMethod scope between the behavior Closures)
        matching parameter list specified via Closure's parameter list, supporting
            typed or untyped params, default params, and varargs.
        not dependent on any external mock library
