Eclipse中JUnit 5（Jupiter）突然出现<terminated>错误求助

运行首个JUnit测试时，JUnit Runner窗口未弹出显示测试结果，控制台仅显示<terminated>提示。此前相同配置的3个项目测试均正常，近期突然全部出现该问题。已排查Maven配置、更换工作区、重装JDK和Eclipse，但问题仍未解决。

排查与解决建议 #

1. 修复JUnit版本混用问题
   测试类同时引入了JUnit 4的org.junit.Test注解和JUnit 5的org.junit.jupiter.api.Assertions类，跨版本混用会导致测试执行逻辑冲突，无法正常触发JUnit Runner。解决：将import org.junit.Test替换为JUnit 5的注解import org.junit.jupiter.api.Test。

2. 统一Maven中JUnit依赖
   确保pom.xml中使用统一的JUnit 5依赖，避免版本冲突：

   <dependency>
       <groupId>org.junit.jupiter</groupId>
       <artifactId>junit-jupiter-api</artifactId>
       <version>5.9.2</version>
       <scope>test</scope>
   </dependency>
   <dependency>
       <groupId>org.junit.jupiter</groupId>
       <artifactId>junit-jupiter-engine</artifactId>
       <version>5.9.2</version>
       <scope>test</scope>
   </dependency>
   

3. 检查Eclipse测试运行配置

   • 右键测试类 → Run As → Run Configurations
   • 在JUnit配置项中，确认Test runner选择JUnit Jupiter（对应JUnit 5），而非JUnit 4
   • 若配置异常，删除现有配置后重新创建测试运行配置

4. 验证测试类目录结构
   确保测试类放置在Maven标准测试目录src/test/java下，Eclipse会自动识别该目录下的测试类，若路径错误可能导致JUnit无法扫描到测试用例。
