Travis CI上的JUnit測試用例初始化錯誤

Question

我想弄清楚Travis CI爲Selenium項目運行我的JUnit測試。當我從我的機器上運行它們（在IntelliJ IDEA中）時，該單元測試工作。

由於測試類似乎沒有錯過任何東西，我想知道爲什麼測試在我的機器上運行得非常好，但在Travis CI上失敗。我的設置有問題嗎？

的.travis.yml文件：

language: java 

jdk: 
    - oraclejdk8 

script: ant test 


#before_install: 
# - cd java 

構建文件：

     <echo message="Build done"/> 
    </target>

    <target name="clean"> 
     <delete> 
      <fileset dir="${basedir}" includes="**/*.class"/> 
     </delete> 
     <echo message="Clean done"/> 
    </target> 
</project>

看來我把TestNg和JUnit搞混了。看看我誤用的進口產品：

import org.testng.annotations.AfterClass; 
import org.testng.annotations.BeforeClass; 
import org.testng.annotations.Test;
