Junit測試在服務器啓動時帶來奇怪的錯誤（logger.DEBUG）

Question

我們有一個tomcat與春天web應用程序。 我們有很多junit測試。

當我們設置記錄器值設置爲「DEBUG」我們得到噸以下錯誤：

06 Mar 2014 12:16:39 TRACE ClassPathScanningCandidateComponentProvider - Scanning file [D:\workspaceNG\.metadata\.plugins\org.eclipse.wst.server.core\tmp2\wtpwebapps\NG\WEB- INF\classes\com\xxx\testing\BaseRollbackTest.class]

任何想法，爲什麼？

Answer 1

堆棧跟蹤了一切：

java.lang.ClassNotFoundException: org.junit.After 

的JUnit或JUnit的正確版本是不是在classpath。

Answer 2

它只是發生在我身上。

在我來說，我是從TestNG的swithching JUnit的（唉）我的所有項目的測試類

遷移時他們，我一直保持一些Java TestNG的文件，逐一下JUnit的，但他們沒有編譯任何更多的（我已經刪除了maven依賴項）。

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

下月食「MAVEN」去掉最後TestNG的文件 也乾淨後 - >「更新項目...它消失

雖然這並不能說明你的情況下，方案可能帶來你點燃！

你必須使用JUnit地方缺少正確的Junit的jar編譯陳舊的測試類...
