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

Mockito.spy介绍

[英]Please refer to the documentation of #spy(Object). Overusing spies hints at code design smells.

This method, in contrast to the original #spy(Object), creates a spy based on class instead of an object. Sometimes it is more convenient to create spy based on the class and avoid providing an instance of a spied object. This is particularly useful for spying on abstract classes because they cannot be instantiated. See also MockSettings#useConstructor(Object...).

Examples:

SomeAbstract spy = spy(SomeAbstract.class); 
//Robust API, via settings builder: 
OtherAbstract spy = mock(OtherAbstract.class, withSettings() 
.useConstructor().defaultAnswer(CALLS_REAL_METHODS)); 
//Mocking a non-static inner abstract class: 
InnerAbstract spy = mock(InnerAbstract.class, withSettings() 
.useConstructor().outerInstance(outerInstance).defaultAnswer(CALLS_REAL_METHODS));

[中]请参阅#spy（Object）的文档。过度使用间谍暗示了代码设计的味道。
与原始的#spy（Object）不同，该方法基于类而不是对象创建一个spy。有时，基于类创建spy并避免提供spied对象的实例更方便。这对于监视抽象类尤其有用，因为它们无法实例化。另请参见MockSettings#useConstructor（对象…）。
示例：

SomeAbstract spy = spy(SomeAbstract.class); 
//Robust API, via settings builder: 
OtherAbstract spy = mock(OtherAbstract.class, withSettings() 
.useConstructor().defaultAnswer(CALLS_REAL_METHODS)); 
//Mocking a non-static inner abstract class: 
InnerAbstract spy = mock(InnerAbstract.class, withSettings() 
.useConstructor().outerInstance(outerInstance).defaultAnswer(CALLS_REAL_METHODS));
