QTP – 自动化对象模型

QTP 本身可以使用 HP-QTP 提供的 COM 接口实现自动化。自动化对象模型是一组对象、方法和属性，可帮助测试人员使用 QTP 界面控制配置设置和执行脚本。下面列出了可以控制（但不限于）的关键配置/操作 –

• 加载测试所需的所有插件
• 在执行时使 QTP 可见
• 使用指定位置打开测试
• 关联函数库
• 指定公共对象同步超时
• 开始和结束迭代
• 启用/禁用智能识别
• 错误设置
• 数据表路径
• 恢复场景设置
• 日志跟踪设置

QTP 11.5x 提供了一个关于自动化对象模型的独家文档，可以通过导航到“开始”>>“所有程序”>>“HP 软件”>>“HP 统一功能测试”>>“文档”>>“统一功能测试自动化参考”。

生成 AOM 脚本

测试人员可以使用“生成脚本”选项从 QTP 本身生成 AOM 脚本。导航到“运行”>>“设置”>>“属性”选项卡>>“生成脚本”，如下所示 –

例子
