Converting Object Repository Based Scripts to Descriptive Programming

Here we discuss how we can convert an Object repository based script to DP based script. For this we will do a simple recording of entering some text on Google.com search text box and clicking the

Google search button

The QTP generated script would look something like below

SystemUtil.Run “C:\Program Files\Internet Explorer\IEXPLORE.EXE”
Browser(”Browser”).Page(”Page”).Sync
Browser(”Browser”).Navigate “http://www.google.com”
Browser(”Browser”).Page(”Google”).WebEdit(”q”).Set “KnowledgeInbox”
Browser(”Browser”).Page(”Google”).WebButton(”Google Search”).Click

All the names used between “” are logical name of the objects in the Object Repository (”Browser”, “Page”, “Google”, “q”, “Google Search”) and are stored in object repository.

Now let’s look the below statement and try and convert it to DP

Browser(”Browser”).Page(”Google”).WebButton(”Google Search”).Click

Converting WebButton(”Google Search”)

The Google Search object present in the OR has following properties
type = submit
name = Google Search
html tag = INPUT

Now to conver the WebButton(”Google Search”) to its DP counterpart we can use two different methods

Method 1 – Using String Description

In this we use string parameters to specify the object properties

Browser(”Browser”).Page(”Google”).WebButton(”type:=Submit”, _
“name:=Google Search”, “html tag:=INPUT”).Click

Method 2 – Using Object Description
In this we first create a description of the object and then use it in the statement

Set oGoogleSearch = Descrition.Create
oGoogleSearch(”type”).Value = “Submit”
oGoogleSearch(”name”).Value = “Google Search”
oGoogleSearch(”html tag”).Value = “INPUT”

Browser(”Browser”).Page(”Google”).WebButton(oGoogleSearch).Click

Difference between string description and Object Description -

String Description
– Uses less memory as strings are used
– Increases statement length in case more than one property is to be used.
– Preferred when property value have regular expression characters which needs to be treated
literally

Object Description
– Requires more memory as objects are created.
– Object creation is as such a overhead
– Increase lines of code due to object creation overhead and property
assignment

DP Converted script

SystemUtil.Run “C:\Program Files\Internet Explorer\IEXPLORE.EXE”
Browser(”micclass:=Browser”).Page(”Page”).Sync
Browser(”micclass:=Browser”).Navigate “http://www.google.com”

Browser(”micclass:=Browser”).Page(”micclass:=Page”).WebEdit(”name:=q”).Set _
“KnowledgeInbox”

Browser(”micclass:=Browser”).Page(”micclass:=Page”) _
.WebButton(”type:=Submit”, “name:=Google Search”, “html tag:=A”).Click
