Programmatic descriptions enable us to create temporary versions of test objects to represent objects from our application.

We can perform operations on those objects without referring to the object repository.

For example, suppose an edit box was added to a form on your Web site. You could use a programmatic description to add a statement in a user-defined function that enters a value in the new edit box, so that QuickTest can identify the object even though you never recorded on the object or added it to the object repository

Syntax
TestObject("PropertyName1:=PropertyValue1", "..." , "PropertyNameX:=PropertyValueX")

TestObject—the test object class.
PropertyName:=PropertyValue—the test object property and its value. Each property:=value pair should be separated by commas and quotation marks.

Example
Browser("Mercury Tours").Page("Mercury Tours").WebEdit("Name:=Author", "Index:=3").Set "Mark Twain”

Window("Text:=Myfile.txt - Notepad").Move 50, 50
Window("Text:=Myfile.txt -Notepad").WinEdit("AttachedText:=Find what:").Set "hello"
Window("Text:=Myfile.txt - Notepad").WinButton("Caption:=Find next").Click
