使用 mockito 验证对象属性值

问题描述

我有一个方法调用，我想用 mockito 模拟.首先，我创建并注入了一个对象实例，将在该实例上调用该方法.我的目标是验证方法调用中的对象之一.

I have a method call which I want to mock with mockito. To start with I have created and injected an instance of an object on which the method will be called. My aim is to verify one of the object in method call.

mockito 是否允许您在调用 mock 方法时断言或验证对象及其属性?

Is there a way that mockito allows you to assert or verify the object and it's attributes when the mock method is called?

例子

Mockito.verify(mockedObject)
       .someMethodOnMockedObject(
              Mockito.<SomeObjectAsArgument>anyObject())

我不想做 anyObject() 我想检查参数对象是否包含一些特定字段

Instead of doing anyObject() i want to check that argument object contains some particular fields

Mockito.verify(mockedObject)
       .someMethodOnMockedObject(
              Mockito.<SomeObjectAsArgument>**compareWithThisObject()**)

推荐答案

添加到 Mockito 的新功能使这变得更加容易，

New feature added to Mockito makes this even easier,

ArgumentCaptor<Person> argument = ArgumentCaptor.forClass(Person.class);
verify(mock).doSomething(argument.capture());
assertEquals("John", argument.getValue().getName());

查看 Mockito 文档

Take a look at Mockito documentation

如果有多个参数，并且只需要捕获单个参数，请使用其他 ArgumentMatchers 包装其余参数:

In case when there are more than one parameters, and capturing of only single param is desired, use other ArgumentMatchers to wrap the rest of the arguments:

verify(mock).doSomething(eq(someValue), eq(someOtherValue), argument.capture());
assertEquals("John", argument.getValue().getName());
