通过InjectMocks Spy注入一个对象 [英] Injection an object though InjectMocks Spy

问题描述

我需要在一个具有@Autowired Logger实现的类上运行一系列单元测试。实现的基本思想是：

I need to run series of unit tests over a class, which has a @Autowired Logger implementation. The base idea of realization was:

@Mock Logger logger;
@InjectMocks
TestedClass tested;

但我想保存日志记录输出功能。

but i want to save the logging output functionality.

Mockito lib是否允许使用@InjectMock注入对象？我见过@Spy注释的例子，但是当我尝试使用它时，我总是得到NullPointerException。我知道我总是可以直接使用反射，但想法是避免这样的代码。

Does Mockito lib allow to inject objects with @InjectMock? I'w seen examples of @Spy annotation, but when i tried to use it, i always got NullPointerException. I know that i can always directly use reflect, but the idea is to avoid such code.

推荐答案

好吧。如果没有答案，我将不得不自己回答。

Well. I'll have to answer it myself if there's no answers.

要通过@InjectMock注释推送实时对象，使用@Spy注释：

To push a live object through the @InjectMock annotation a @Spy annotation is used:

@Spy
Logger logger = LoggerFactory.getLogger("");
@InjectMocks
TestedClass tested = new TestedClass();

唯一的问题是@Spy无法处理最终（以及其他一些东西）类，其中我在我的案例中打了个招呼。

The only thing is that @Spy cant handle final(and some other things) classes, on which i struck on in my case.
