Java 尝试运行单元测试时出现Junit错误

我得到这个错误：

java.lang.ClassNotFoundException: com.apache.camel.example.tests.ReportIncidentRoutesTest

这是我收到的新错误的更新堆栈跟踪。在运行配置中，我确实让它指向这个类，所以我不确定为什么我仍然得到这个错误

}

编译时junit 3似乎在类路径中（假设您在使用junit api时没有遇到编译错误），但在运行时却没有，因此存在一些类路径不匹配的问题

---

您似乎是通过eclipse测试运行程序运行测试的，它是否配置为与编写测试所用的junit版本相同？

如何运行单元测试？如何构建发布jar？我正在做一个eclipse运行-->JUnit测试，我的发布jar将打包在部署到tomcat服务器的WAR文件中。尝试在我们的运行配置Eclipse JUnit runner中为您的类检查默认运行程序。另外，请确保有效的JUnit jar位于特定运行配置的类路径中。啊，是的，它似乎不在运行配置的类路径中，我现在收到一个不同的错误，表示测试“未找到类”，尽管我在运行配置中明确说明了这一点，我之前遇到了一个不同的错误，我查看了运行配置，发现它被设置为JUNIT 4，所以我将其更改为3，但随后这个错误开始出现。我猜eclipse配置有一个到JUNIT 3.jar文件的错误路径，但我不知道如何查找和修复该配置，抱歉。
