检查EasyMock模拟是否处于重放模式/状态

Question

是否可以确定EasyMock模拟是否处于重放模式？

类似的东西：

if (EasyMock.isReplayed(mock))
  // do something

Answer 1

为了检查模拟的state，你需要 unProxy 你的模拟并检查该模拟的状态集，一个状态是ReplayState。由于EasyMock适用于Java Proxies，因此非常简单：

EasyMock.replay(mock); // setting replay state to a mock object

// stripping proxy and getting the invocation handler
InvocationHandler invocationHandler = Proxy.getInvocationHandler(mock); 


// for easyMock, invocation handler holds the state of the mock 
ObjectMethodsFilter objectMethodsFilter = (ObjectMethodsFilter) invocationHandler; 

// not the not so elegant part:
// this: objectMethodsFilter.getDelegate().getControl().getState() 
// retrieves  the state instance that can be checked if it is an 
// instance of ReplayState.class
boolean inReplayState = objectMethodsFilter.getDelegate()
    .getControl().getState() instanceof ReplayState;

就是这样！这将打印true因为已设置为Replay

对于版本3.1，您可以使用：

ClassExtensionHelper.getControl(mock).getState() instanceof ReplayState
