本文整理了Java中org.mockito.Mockito.doNothing()方法的一些代码示例，展示了Mockito.doNothing()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Mockito.doNothing()方法的具体详情如下：
包路径：org.mockito.Mockito
类名称：Mockito
方法名：doNothing

Mockito.doNothing介绍

[英]Use doNothing() for setting void methods to do nothing. Beware that void methods on mocks do nothing by default! However, there are rare situations when doNothing() comes handy:

  1. Stubbing consecutive calls on a void method:
doNothing(). 
doThrow(new RuntimeException()) 
.when(mock).someVoidMethod(); 
//does nothing the first time: 
mock.someVoidMethod(); 
//throws RuntimeException the next time: 
mock.someVoidMethod();
  1. When you spy real objects and you want the void method to do nothing:
List list = new LinkedList(); 
List spy = spy(list); 
//let's make clear() do nothing 
doNothing().when(spy).clear(); 
spy.add("one"); 
//clear() does nothing, so the list still contains "one" 
spy.clear();

See examples in javadoc for Mockito class
[中]使用doNothing()将void方法设置为不执行任何操作。注意，mock上的void方法在默认情况下不起任何作用！但是，很少有情况下doNothing（）会派上用场：
1.在void方法上存根连续调用：

doNothing(). 
doThrow(new RuntimeException()) 
.when(mock).someVoidMethod(); 
//does nothing the first time: 
mock.someVoidMethod(); 
//throws RuntimeException the next time: 
mock.someVoidMethod();

1.当你监视真实的对象时，你希望void方法什么都不做：

List list = new LinkedList(); 
List spy = spy(list); 
//let's make clear() do nothing 
doNothing().when(spy).clear(); 
spy.add("one"); 
//clear() does nothing, so the list still contains "one" 
spy.clear();
