Tutorial 22 - Ordinal Identifiers

This tutorial introduces Ordinal Identifiers .It is recommended you complete Tutorials 19 , 20 & 21 before taking this tutorial.




points to note:

If mandatory and assistive properties are insufficient to identify an object during record session ,QTP uses Ordinal Identifier in addition to other captured properties to identify the objects during a record session
By default, an ordinal identifier type exists for each test object class.
In the Object Identification Window, you can modify the default Ordinal Identifier for an Object


There 3 types of Ordinal Identifiers
* 1) Index based
* 2) Location based
* 3) Creation Time


Index Based

* When using Index based ordinal identifier, while recording , QTP will assign a value to INDEX property of an object
* The value is based on the order in which the object appears within the source code.
* The first occurrence has value 0
* Index property values are object-specific.
* Therefore, if you use Index:=3 to describe a WebEdit test object, Quick Test searches for the fourth WebEdit object on the page.
* Likewise , you use Index:=1 to describe a WebButton test object, Quick Test searches for the third WebButton object on the page



Location Based
* When using location based ordinal identifier, while recording , QTP will assign a value to LOCATION property of an object to uniquely identify the object.
* The value is based on the order in which the object appears within the window, frame, or dialog box, in relation to other objects with identical properties.
* The first occurrence of the object is 0.
* Values are assigned in columns from top to bottom, and left to right.


Creation Time
* When using creation time ordinal identifier, while recording , QTP will assign a value to CreationTime property of an WebBrowser
* The Identifier is only available for the Web Environment
* This value indicates the order in which the browser was opened relative to other open browsers.
* The first browser that opens while recording receives the value CreationTime=0 and succeeding browsers are give values 1 , 2 , 3 … an so on
