Manually instantiating the @InjectMock annotated field

阅读更多关于 Manually instantiating the @InjectMock annotated field

问题 I have gone through some of the blogs in order to understand the basics of how Mockito annotations work. However I am facing a doubt as to when does one go for manually instantiating the field annotated with @InjectMocks i.e @InjectMocks A a = new A(); And when does one rely on MockitoAnnotations.initMocks() functionality to do the same : @InjectMocks A a; Does this depend on the JunitTestRunner that we employ to run the test cases or is it dependent on the Mockito framework version? 回答1: It

SpringBoot 单元测试利器——Mockito

Mockito 是一种 Java mock 框架，他主要是用来做 mock 测试的，他可以模拟任何 Spring 管理的 bean、模拟方法的返回值、模拟抛出异常...等，在了解 Mockito 的具体用法之前，得先了解什麽是 mock 测试 1. 什么是 mock 测试？ mock 测试就是在测试过程中，创建一个假的对象，避免你为了测试一个方法，却要自行构建整个 bean 的依赖链像是以下这张图，类 A 需要调用类 B 和类 C，而类 B 和类 C 又需要调用其他类如 D、E、F 等，假设类 D 是一个外部服务，那就会很难测，因为你的返回结果会直接的受外部服务影响，导致你的单元测试可能今天会过、但明天就过不了了而当我们引入 mock 测试时，就可以创建一个假的对象，替换掉真实的 bean B 和 C，这样在调用B、C的方法时，实际上就会去调用这个假的 mock 对象的方法，而我们就可以自己设定这个 mock 对象的参数和期望结果，让我们可以专注在测试当前的类 A，而不会受到其他的外部服务影响，这样测试效率就能提高很多 2. Mockito 简介说完了 mock 测试的概念，接下来我们进入到今天的主题，Mockito Mockito 是一种 Java mock 框架，他主要就是用来做 mock 测试的，他可以模拟任何 Spring 管理的 bean、模拟方法的返回值

1 mockito概述 Mockito is a mocking framework that tastes really good. It lets you write beautiful tests with a clean & simple API. Mockito doesn’t give you hangover because the tests are very readable and they produce clean verification errors. Mockito是一个非常不错的模拟框架。它使您可以使用干净简单的API编写漂亮的测试。 Mockito不会给您带来麻烦，因为这些测试可读性强，并且会产生清晰的验证错误。官方说明-how简要版本 mockito官方文档-详细版本特性和动机github说明其特性如下： mock具体的类和接口；小注释语法糖-@Mock 验证错误是干净的-单击堆栈跟踪以查看测试中失败的验证；单击异常原因以导航到代码中的实际交互。堆栈跟踪始终是干净的。允许按顺序进行灵活的验证（例如：按顺序进行验证，而不是每次交互都进行验证）支持精确次数和最少一次的验证使用参数匹配器（anyObject（），anyString（）或refEq（）进行基于反射的相等匹配）的灵活验证或存根

问题 If I mock a method to return a new instance of some object, how can I capture the returned instance? E.g.: when(mock.someMethod(anyString())).thenAnswer(new Answer() { Object answer(InvocationOnMock invocation) { Object[] args = invocation.getArguments(); Object mock = invocation.getMock(); return new Foo(args[0]) } }); Obviously, I can have a field of type Foo and inside answer set it to the new instance, but is there a nicer way? Something like ArgumentCaptor? 回答1: Looks like you want to
