【中文标题】@ExtendWith(SpringExtension.class) 不工作【英文标题】:@ExtendWith(SpringExtension.class) not working 【发布时间】:2018-09-24 19:47:41 【问题描述】:我正在尝试在 spring-boot 2.x 项目上使用 Junit 5 来测试控制器。
以下工作正常
import static org.springframework.test.web.servlet.request.MockMvcRequestBuilders.get;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
import static org.springframework.test.web.servlet.setup.MockMvcBuilders.webAppContextSetup;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.autoconfigure.web.servlet.WebMvcTest;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.MediaType;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.web.context.WebApplicationContext;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
@WebMvcTest(TypesController.class)
@RunWith(SpringRunner.class)
public class TypesControllerTest
@Autowired
WebApplicationContext wac;
@Test
public void testTypes() throws Exception
webAppContextSetup(wac).build().perform(get("/types").accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk()).andExpect(content().contentType("application/json;charset=UTF-8"));
@EnableWebMvc
@Configuration
@ComponentScan(basePackageClasses = TypesController.class )
static class Config
但是如果我把它改成使用 SpringExtention,
..
import org.springframework.test.context.junit.jupiter.SpringExtension;
import org.junit.jupiter.api.extension.ExtendWith;
..
@ExtendWith(SpringExtension.class)
@WebMvcTest(TypesController.class)
public class TypesControllerTest
..
我收到以下异常:

【问题讨论】:
【参考方案1】:你仍然没有用 JUnit 5 运行。一行如
org.junit.runners.BlockJUnit4ClassRunner.runChild(BlockJUnit4ClassRunner.java:57)
表明了这一点。可能你还在使用错误的@Test
注解。
【讨论】:
? 将其更改为import org.junit.jupiter.api.Test;
成功了!谢谢
aaah,在迁移到 junit5 时,这是一个非常愚蠢的简单错误:/
@AgostonHorvath ...一天两次。我的情况。【参考方案2】:
我也遇到了完全相同的问题。由于错误的 @Test 注释,未加载 Spring 上下文。 我导入了 org.junit.jupiter.api.Test 而不是 org.junit.Test 并解决了问题。
【讨论】:
以上是关于@ExtendWith(SpringExtension.class) 不工作的主要内容,如果未能解决你的问题,请参考以下文章
@ExtendWith(SpringExtension.class) 不工作
未解决的参考:SpringExtension 使用 @ExtendWith 注释
Spring JUnit 5 ExtendWith TestContainer
如何修复类型不匹配:@ExtendWith(SpringExtension::class) Class -> Class in intellij?
无法在使用 @ExtendWith(SpringExtension.class) 运行的 Spring Boot 单元测试中注入应用程序上下文
