问题描述

当我一起使用webAppContextSetup时，很难使Mockito和MockMvc一起工作.我很好奇是否是因为我以一种他们从未打算过的方式将两者混合在一起.

I'm having difficulties getting Mockito and MockMvc working together when I use the webAppContextSetup together. I'm curious if it's because I'm mixing the two in a way they were never intended.

来源: https://github.com/zgardner/spring-boot-intro/blob/master/src/test/java/com/zgardner/springBootIntro/controller/PersonControllerTest.java

这是我正在运行的测试:

Here is the test I'm running:

package com.zgardner.springBootIntro.controller;

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.support.DefaultListableBeanFactory;
import org.springframework.boot.test.SpringApplicationConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.test.web.servlet.MockMvc;
import org.springframework.test.web.servlet.setup.MockMvcBuilders;
import org.springframework.web.context.WebApplicationContext;

import static java.lang.Math.toIntExact;
import static org.hamcrest.Matchers.is;
import static org.mockito.MockitoAnnotations.initMocks;
import static org.mockito.Mockito.when;
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultHandlers.print;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.jsonPath;
import static org.springframework.test.web.servlet.setup.MockMvcBuilders.webAppContextSetup;

import com.zgardner.springBootIntro.Application;
import com.zgardner.springBootIntro.service.PersonService;
import com.zgardner.springBootIntro.model.PersonModel;

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
@WebAppConfiguration
public class PersonControllerTest {

    private MockMvc mockMvc;

    @Autowired
    private WebApplicationContext webApplicationContext;

    @Autowired
    private DefaultListableBeanFactory beanFactory;

    @Mock
    private PersonService personService;

    @InjectMocks
    private PersonController personController;

    @Before
    public void setup() {
        initMocks(this);

        // beanFactory.destroySingleton("personController");
        // beanFactory.registerSingleton("personController", personController);

        mockMvc = MockMvcBuilders.webAppContextSetup(webApplicationContext).build();
    }

    @Test
    public void getPersonById() throws Exception {
        Long id = 999L;
        String name = "Person name";

        when(personService.findById(id)).thenReturn(new PersonModel(id, name));

        mockMvc.perform(get("/person/getPersonById/" + id))
            .andDo(print())
            .andExpect(jsonPath("$.id", is(toIntExact(id))))
            .andExpect(jsonPath("$.name", is(name)));
    }
}

我期望当mockMvc执行该HTTP调用的模拟时，它将使用我在测试中定义的PersonController.但是，当我调试通过时，它使用的是由SpringJunit4ClassRunner在测试启动时创建的PersonController.

I was expecting that when mockMvc performed the mock of that HTTP call, it would use the PersonController I defined in my test. But when I debug through, it's using the PersonController which was created by the SpringJunit4ClassRunner on the test boot up.

我发现了两种方法可以使它起作用:

I found two ways to get this to work:

注入bean工厂，删除旧的personController单例，然后添加我自己的.这很丑，我不是粉丝.
使用standaloneSetup而不是webAppContextSetup连接所有内容.我可以这样做，因为我不必接触bean工厂.

以下是我发现的一些与该主题有所不同的文章:

Here are some different articles I've found that somewhat touch on the topic:

Spring教程-构建REST服务这只是在回购协议中自动布线以清除集成测试之前的数据.
使用Spring MVC测试框架和Mockito测试控制器这将Mockito与webAppContextSetup一起使用，但这是在Spring 3中.(我正在使用Spring Boot)
无法在Spring MVC Controller测试中模拟服务类这使用了standaloneSetup，在我的情况下也可以使用.

Spring Tutorial - Building REST Services This just autowires in the repos to clear out the data before the integration test takes place.
Use Spring MVC Test framework and Mockito to test controllers This uses Mockito along with webAppContextSetup, but this is in Spring 3. (I'm using Spring Boot)
Unable to mock Service class in Spring MVC Controller tests This uses the standaloneSetup, which does work in my case too.

有想法吗?

standaloneSetup

Mockito是否应在Spring 4中与MockMvc的webAppContextSetup一起使用?
