This article discusses 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”) as shown in below image
Object Repository for the recorded script
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 GoogleSearch = Descrition.Create oGoogleSearch("type").Value = "Submit" oGoogleSearch("name").Value = "Google Search" oGoogleSearch("html tag").Value = "INPUT" Browser("Browser").Page("Google").WebButton(oGoogleSearch).Click |
Which method of DP to choose?
The later articles of this DP Part X series would be discussing in details when and where to use for which method. For now just understand that both methods have their own advantage and disadvantages
Few difference IMO are listed below
String Description | Object Description |
Uses less memory as strings are used | Requires more memory as objects are created. Object creation is as such a overhead |
Increases statement length in case more than one property is to be used | Increase lines of code due to object creation overhead and property assignment |
| Preferred when property value have regular expression characters which needs to be treated literally (explained in one of the later articles) |
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 |
