我从以下网址下载了 js-test-driver 的源代码:http: //js-test-driver.googlecode.com/svn/tags/1.2

它编译得很好,但是其中一个单元测试失败了:

[junit] Tests run: 1, Failures: 1, Errors: 0, Time elapsed: 0.012 sec
[junit] Test com.google.jstestdriver.eclipse.ui.views.FailureOnlyViewerFilterTest FAILED

我正在使用: - ANT 1.7.1 - javac 1.6.0_12

我正在尝试在 Eclipse 3.5.1 Galileo 上安装 js-test-driver 插件

尽管测试失败,我还是通过复制(从 svn 导出)已编译的功能和插件目录将插件安装到我的 C:\eclipse\dropins\js-test-driver 目录中,看看它是否会产生任何提示问题是。

当我启动 Eclipse 时,使用 Window->Show View->Other...Other->JsTestDriver 将插件添加到面板

添加了面板的插件,但它显示以下错误而不是面板中的插件:

无法创建视图:插件 com.google.jstestdriver.eclipse.ui 无法加载类 com.google.jstestdriver.eclipse.ui.views.JsTestDriverView。

然后在单击详细信息后,我得到以下堆栈跟踪:

此外,如果我转到 Window->Preferences 中的设置并尝试查看 JS Test Driver Preferences,我会看到以下对话框:

出现问题 无法创建选定的首选项页面。com.google.jstestdriver.eclipse.ui.WorkbenchPreferencePage

我对这个问题的修复是基于对http://code.google.com/p/js-test-driver/wiki/UsingTheEclipsePlugin的评论:

安装 Eclipse 插件时,如果软件列表中包含“没有分类项目”的项目,请取消勾选下面的“按类别分组项目”复选框。

这解决了我在初始安装后显示或尝试配置插件选项卡时遇到的上述错误。

此错误消息说,类加载器未找到类 com.google.jstestdriver.eclipse.ui.views.JsTestDriverView。可能的解决方案:

  • 琐碎:编译的解决方案中是否有正确命名的类文件?
  • 如果存在正确的类文件,请查看该视图代码的源代码,并查看它试图加载的内容。
  • 检查依赖关系,因为在不满足依赖关系的情况下(没有正确写下来),类加载器可能找不到某些类。
  • 在项目中查找激活器类,并检查它们在做什么。他们也可能引入这样的问题。
