Junit 测试在服务器启动时带来奇怪的错误 (logger.DEBUG)

Question

我们有一个带有 spring web 应用程序的 tomcat。 我们有很多junit测试。

当我们将记录器值设置为“DEBUG”时，我们会收到大量以下错误：

有什么想法吗？

Answer 1

这只是发生在我身上。

在我的情况下，我正在从 TestNG 切换到 JUnit（唉）我所有的项目测试类

我在迁移时保留了一些 java testNG 文件，在 JUnit 下一个接一个，但它们不再编译（我已经删除了 maven 依赖项）。

(AnnotationAttributesReadingVisitor.java:184).visitEnd() - Failed to class-load type while    reading annotation metadata. etc
java.lang.ClassNotFoundException: BeforeClass

删除最后一个 testNG 文件后 并且在 eclipse "MAVEN" -> "Update Project... 它消失了。

虽然它没有解释你的情况，但这个场景可以给你带来光明！

您在某处使用 Junit 的陈旧测试类缺少正确的 Junit jar 来编译...

Answer 2

堆栈跟踪说明了一切：

java.lang.ClassNotFoundException: org.junit.After

jUnit 或正确版本的 jUnit 不在类路径中。
