软件测试工具QTP的3类顺序标识（Ordinal Identifiers）
对于顺序标识（Ordinal Identifiers），QTP的帮助文档是这样说的：
An ordinal identifier assigns a numerical value to a test object that indicates its order or location relative to other objects with an otherwise identical description (objects that have the same values for all properties). This ordered value provides a backup mechanism that enables QuickTest to create a unique description to recognize an object when the defined properties are not sufficient to do so.
总共有3类这样的顺序标识（Ordinal Identifiers）：Location, Index 和 CreationTime
其中CreationTime仅适用于Browser对象。
顺序标识（Ordinal Identifiers）通常在描述性编程时使用。
例1：location（location顺序标识是用上到下进行的）
| 'Text Box 1 Browser("title:=.*Descriptive.*").Page("micclass:=Page").WebEdit("name:=dpTest","location:=0").Set "1" 'Text Box 3 Browser("title:=.*Descriptive.*").Page("micclass:=Page").WebEdit("name:=dpTest","location:=1").Set "2" 'Text Box 2 Browser("title:=.*Descriptive.*").Page("micclass:=Page").WebEdit("name:=dpTest","location:=2").Set "3" 'Text Box 4 Browser("title:=.*Descriptive.*").Page("micclass:=Page").WebEdit("name:=dpTest","location:=3").Set "4" |
