QTP - 框架设计



让我们通过一个示例应用程序来设计一个简单的框架。我们将自动化被测应用程序的几个场景,并编写可重用的函数。

被测示例应用程序是“计算器”,它是Windows自带的一个默认应用程序。现在让我们创建框架的不同组件。在这里,我们将开发一个混合框架并使用对象库,因为它是一个相当简单的应用程序。但是,此框架也可以扩展以支持复杂的应用程序。

框架的文件夹结构如下所示:

QTP Framework Folder Structure

文件夹结构说明:

  • 主驱动脚本 - 驱动整个执行的脚本。它执行执行所需的先决条件和初始设置。

  • 库文件 - 构成函数库的相关函数。

  • 数据表 - 执行所需测试数据。

  • 对象库 - 对象及其属性,使QTP能够无缝识别对象。

  • 执行日志 - 该文件夹包含执行日志文件,其中包含用户函数和函数执行历史记录。
