例测试的HtmlUnit失败

我试图通过Junit的样品测试的HtmlUnit运行情况。例测试的HtmlUnit失败

我的项目是基于Maven的。我是否需要在编译和测试期间将所有依赖项添加到我的POM中？ http://htmlunit.sourceforge.net/dependencies.html 现在我已经加入化的HtmlUnit依赖，httpconnections和nekohtml。

样品测试：

@Test 
public void homePage() throws Exception { 
    WebClient webClient = new WebClient(BrowserVersion.CHROME_16); 
    final HtmlPage page = webClient.getPage("http://htmlunit.sourceforge.net"); 

    assertEquals("HtmlUnit - Welcome to HtmlUnit", page.getTitleText()); 

    final String pageAsXml = page.asXml(); 
    assertTrue(pageAsXml.contains("<body class=\"composite\">")); 

    final String pageAsText = page.asText(); 
    assertTrue(pageAsText.contains("Support for the HTTP and HTTPS protocols")); 

    webClient.closeAllWindows(); 
}

测试失败W¯¯以下错误：

我不认为你得到的错误有什么在你的'pom.xml'文件中声明的依赖关系。 –

问题变成了我在我的POM我的项目依赖的一个不同是拉，和不兼容，nekoHTML的版本。

一旦我删除有问题的依赖（这是一个缓缴从项目IM测试，而不是这个项目，我用来测试其他凸出 - 说来话长）一切工作就好了。

是，同样的错误，通过去除旧版本nekoHTML的解决。谢谢。 – Buddha

你还记得什么违规的依存度？我有同样的错误... – jlars62

@ jlars62，你可能有这样的事情在你的POM：

<dependency> 
     <groupId>net.sourceforge.htmlunit</groupId> 
     <artifactId>htmlunit</artifactId> 
     <version>2.14</version> 
    </dependency>

，添加排除如下：

<dependency> 
     <groupId>net.sourceforge.htmlunit</groupId> 
     <artifactId>htmlunit</artifactId> 
     <version>2.14</version> 
     **<exclusions> 
      <exclusion> 
       <groupId>net.sourceforge.nekohtml</groupId> 
       <artifactId>nekohtml</artifactId> 
      </exclusion> 
     </exclusions>** 
    </dependency>
