java - 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？

就像是：

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

Answer 1

为了检查state一个模拟，您需要取消代理您的模拟并检查该模拟的状态集，其中一个状态是ReplayState. 由于 EasyMock 与 Java 代理一起工作，这很容易：

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

也许对于 3.1 版，您可以使用：

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