QTP 11.0中的Web可扩展性加载项疑难解答

Question

我正在尝试使用QTP 11.0 Web可扩展性插件在对象识别下显示自定义Web元素类型。

我的扩展程序中有四个文件，如问题末尾所示。我的问题是没有任何对象出现在Object Identification窗口中。我以为我可能做错了，所以我加载了SDK附带的GWT示例，但它也没有在对象标识中显示任何内容！

QTP是否保留日志或任何类型的调试信息，说明我可能遇到的错误类型，或者是否按预期工作，这些自定义对象甚至不会假设显示在对象识别窗口中？如果是这样，为什么？

QTP从 HiddenTestObjects.xml 文件中获取用于对象识别的属性。在那里，您可以指定哪个属性是 ForDescription 和智能标识（请查看架构或文档以获取更多详细信息）。

QTP允许通过对象识别对话框在机器到机器的基础上覆盖这些设置，但AFAIK的假设是Web可扩展性作者最了解应该使用哪些属性。

如果您认为让用户覆盖您在 HiddenTestObjects.xml 中列出的对象识别规则很重要，则应该向HP打开增强请求。否则，我所知道的唯一方法是指示用户在本地编辑 HiddenTestObjects.xml 。
