QTP - 设计框架
让我们通过一个示例应用程序来设计一个简单的框架。我们将自动化测试应用程序的几个场景并编写可重用的功能。
测试的示例应用程序是"计算器"，它是 Windows 的一部分，是默认应用程序。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存储库，因为它是一个相当简单的应用程序。但是，这个框架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 −
文件夹结构的说明 −
主驱动程序脚本 −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 − 构成函数库的关联函数。
数据表 − 执行所需的测试数据。
对象存储库 − 使 QTP 能够无缝识别对象的对象及其属性。
执行日志 − 该文件夹包含带有用户函数和函数执行历史记录的执行日志文件。

对象存储库
对象存储库包含用户将要操作的所有对象。下面给出的图像显示了添加到存储库中名为 calc.tsr 的所有对象的列表
数据表
数据表包含驱动测试的关键字，还包含 QTP 将对对象执行操作的测试数据。
执行日志
执行日志文件或输出文件包含用户操作和功能日志，使测试人员能够在脚本失败时进行调试。
