Examples of org.apache.aries.unittest.mocks.Skeleton

org.apache.aries.unittest.mocks.Skeleton
The Skeleton class is an implementation of the java.lang.reflect.InvocationHandler that can be used for dynamic mock objects.
1. The static newMock methods can be used to create completely new mock objects backed by an entirely new skeleton.
2. The static getSkeleton method can be used to obtain the skeleton backing a given mock.
3. The createMock methods can be used to create a new mock object based on the skeleton that is invoked.
4. The registerMethodCallHandler method can be used to register a handler that will be invoked when a method is called.
5. The registerReturnTypeHandler method can be used to register a handler that will be invoked when a method with a specific return type is invoked. It should be noted that registered ReturnTypeHandlers will be invoked only if a method call handler has not been registered for the method that was invoked.
6. The setReturnValue method can be used to set a value that will be returned when a method is invoked.
7. The checkCalls methods can be used to determine if the methods in the list should have been called. They return a boolean to indicate if the expected calls occurred.
8. The assertCalls method performs the same operation as the checkCalls, but throws an junit.framework.AssertionFailedError if the calls don't match. This intended for use within the junit test framework
9. If no method call or return type handlers have been registered for a call then if the return type is an interface then a mock that implements that interface will be returned, otherwise null will be returned.
