我在将MockMvc注入到我的测试类中时遇到了问题。我尝试了几个选项,但都不起作用。
1选项:与这里基本相同,手工创建MockMvc
@Autowire MockMvc -Spring数据复位
2个选项:
package com.application.controller;
import org.junit.jupiter.api.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.AutoConfigureMockMvc;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.web.servlet.MockMvc;
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.status;
@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class DishControllerTest {
@Autowired
public MockMvc mockMvc;
@Test
void getDishes() throws Exception {
this.mockMvc.perform(
get("/"))
.andDo(print())
.andExpect(status().isOk());
}
1.还尝试了使用@WebMvcTest注解而不是@AutoConfigureMockMvc的第二个选项
MockMVC始终为空。StackTrace:

你知道为什么会发生这种情况吗?有没有可能是因为pom依赖关系冲突?
4条答案
按热度按时间n53p2ov01#
抛出异常的原因是您使用的是Junit Jupiter
@Test
注解,而不是Junit 4@Runwith
注解。您应该 * 或者 * 使用Junit 4中的org.junit.Test
, 或者 * 使用@ExtendWith(SpringExtension.class)
注解该类以使用Junit Jupiter。@WebMvcTest
可能就是您想要的(它暗示着@AutoConfigureMockMvc
以及其他内容)。相关文件
xriantvc2#
这是兼容性问题+注解使用不正确。
我做了什么:
1.将独立JUnit和Mockito依赖关系替换为
spring-boot-starter-test
1.升级注解以使用junit.jupiter而不是junit.test
下面是工作代码:
qvtsj1bj3#
对于
Junit 5
,我们不需要@SpringBootTest
,您可以删除它,否则它将查找实际配置。此外,将您的
@RunWith(SpringRunner.class)
更改为@ExtendWith(SpringExtension.class)
或@ExtendWith(MockitoExtension.class)
。代码中似乎也缺少
@InjectMocks
。最后需要添加
mockMvc = MockMvcBuilders.standaloneSetup(DishController)
。在您的端尝试下面的代码,它应该工作。
n8ghc7c14#
有同样的问题!
Spring Boot 2.4.3
和Junit 5
。最后,我尝试在maven中远程调试测试,发现没有加载整个上下文,并且没有调用我的
@BeforeEach
方法。经过几次搜索,问题是缺少
maven-surefire-plugin
。添加3.0.0-M7
版本解决了问题。
