Eclipse运行Karate Runner作为JUnit测试无输出，Maven命令行执行正常

在Eclipse中运行下方的Karate Runner文件作为JUnit测试时，控制台无任何输出，JUnit Explorer也没有显示执行记录，但使用mvn test命令行执行该文件则可正常运行。

解决步骤 #

1. 修复代码语法错误

@BeforeClass方法缺少闭合大括号，会导致编译失败，Eclipse直接跳过测试执行。修正后：

@BeforeClass
public static void beforeClass() throws Exception {
    System.setProperty("karate.env", "SAT");
} // 补上缺失的大括号

2. 移除冲突依赖与注解

• 代码同时引入了JUnit 4（org.junit.Test）和JUnit 5（com.intuit.karate.junit5.Karate），版本冲突会导致Eclipse的JUnit Runner识别异常。根据需求二选一：
  • 用JUnit 4：删除com.intuit.karate.junit5.Karate导入，确保项目依赖仅包含JUnit 4。
  • 用JUnit 5：替换@Test为@Karate.Test，改用JUnit 5的@BeforeAll替代@BeforeClass。
• @CucumberOptions是Cucumber原生注解，和Karate的Runner API不兼容，直接删除该注解。

3. 修正路径空格问题

路径classpath: SpendManagement中SpendManagement前有空格，会导致Karate无法定位Feature文件，改为classpath:SpendManagement。

4. 调整Eclipse测试配置

• 右键测试类 → Run As → Run Configurations，确认选择的JUnit版本（4或5）与代码依赖一致。
• 右键项目 → Maven → Update Project，刷新依赖确保没有缺失或冲突。

5. 修正报告生成代码

代码中Collection<File>和List<String>是HTML转义字符，改为正常的<和>；同时new ArrayList(jsonFiles.size())需添加泛型<String>。
