本文整理了Java中org.mockito.Mockito.stub()方法的一些代码示例，展示了Mockito.stub()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.stub()方法的具体详情如下：
包路径：org.mockito.Mockito
类名称：Mockito
方法名：stub

Mockito.stub介绍

[英]Stubs a method call with return value or an exception. E.g:

stub(mock.someMethod()).toReturn(10); 
//you can use flexible argument matchers, e.g: 
stub(mock.someMethod(anyString())).toReturn(10); 
//setting exception to be thrown: 
stub(mock.someMethod("some arg")).toThrow(new RuntimeException()); 
//you can stub with different behavior for consecutive method calls. 
//Last stubbing (e.g: toReturn("foo")) determines the behavior for further consecutive calls. 
stub(mock.someMethod("some arg")) 
.toThrow(new RuntimeException()) 
.toReturn("foo");

Some users find stub() confusing therefore Mockito#when(Object) is recommended over stub()

//Instead of: 
stub(mock.count()).toReturn(10); 
//You can do: 
when(mock.count()).thenReturn(10);

For stubbing void methods with throwables see: Mockito#doThrow(Throwable)

Stubbing can be overridden: for example common stubbing can go to fixture setup but the test methods can override it. Please note that overridding stubbing is a potential code smell that points out too much stubbing.

Once stubbed, the method will always return stubbed value regardless of how many times it is called.

Last stubbing is more important - when you stubbed the same method with the same arguments many times.

Although it is possible to verify a stubbed invocation, usually it's just redundant. Let's say you've stubbed foo.bar(). If your code cares what foo.bar() returns then something else breaks(often before even verify() gets executed). If your code doesn't care what get(0) returns then it should not be stubbed. Not convinced? See here.
