Class SimpleMock

java.lang.Object

net.sf.kdgcommons.test.SimpleMock

All Implemented Interfaces:

InvocationHandler

public class SimpleMock
extends Object
implements InvocationHandler

A simple mock object using a reflection proxy: you tell it the type of interface that you want to mock, and it records invocations on that interface. You can make assertions on those invocations.

All invoked methods return null. Override invoke(java.lang.Object, java.lang.reflect.Method, java.lang.Object[]) if you want to change this behavior, but be sure to call the superclass implementation (otherwise it won't record the invocation).

A single instance can mock multiple objects, however method invocations will be interleaved. Doing so is primarily useful when you simply need a dummy object as a method parameter, and don't actually use it.
