In this
article, we will try to understand Automation Object Model in QTP through
subjective and multiple choice questions:
Question 1: What is UFT AOM?
Answer: AOM stands for Automation
Object Model.The UFT AOM is a
set of objects, methods, and properties that enable you to control essentially
all test settings ad test options. Using the objects,
methods, and properties exposed by the UFT automation object model, along with
loops and conditional statements, we can perform following tasks using
Automation object model:
1. Execution of
Test Scripts from VB Script. This helps in execution of tests from QTP and
scheduling tests to run on remote machine. Test can be run in host
machine/remote machine but QTP needs to be installed in host/remote machine in
which test script needs to be executed.
2. We can
change configurations (Test Settings and options) at runtime of QTP tests.
3. We can save
test or component using AOM.
4. Using
Initialization script that launch UFT automatically can enable same
settings/options executing from multiple machines.
Question 2: We can create an object of Quick Test in VBScript using ......
a.
Set qtApp =
CreateObject("QuickTest.Application", "MyServer")
b.
Set qtApp =
CreateObject("QuickTest.Application")
c.
Set qtApp As
CreateObject("QuickTest.Application")
d.
Set qtApp as
CreateObject(“Scripting.QuickTest”)
Answer: We
can create an object of QuickTest in VBScript using a) or b). We need to
provide server details as shown in option a), in case we need to run test on
a remote machine. In case we have to run test in the same machine, we can use
option b), i.e without Server Parameter.
Question 3: How can we associate a library at runtime with QTP test using AOM?
Answer: We
can add a library using AOM as follows:
Create an object of QTP object.
Set qtApp =
CreateObject(“Quicktest.Application”);
Multiple libraries can be associated with
test as follows:
qtApp.Test.Settings.Resources.Libraries.Add
"C:\Common_Func.vbs"
qtApp.Test.Settings.Resources.Libraries.Add "C:\Business_Func.vbs"
files = "C:\Common_Func.vbs| C:\Business_Func.vbs"
qtApp.Test.Settings.Resources.Libraries.Add(files)
qtApp.Test.Settings.Resources.Libraries.Add "C:\Business_Func.vbs"
files = "C:\Common_Func.vbs| C:\Business_Func.vbs"
qtApp.Test.Settings.Resources.Libraries.Add(files)
In addition
to AOM, we can associate libraries using function LoadFunctionLibrary FileName
or ExecuteFile FileName
Question 4: Can we generate script automatically for all test settings and options: Yes/No
Answer: We
can generate AOM scripts for all test settings, and test options in QTP.
a.
Script for
all the test settings can be generated from File>Settings>Properties
b.
Script for
all the test option can be generated from Tools>Options>GUI Testing>General
Question 5: How can we associate repositories with a test in QTP using AOM?
Answer: An object Repository is associated
with action in the test and not the test as whole. We can associate object
repository with an action as shown in the example below:
Set Qtpapp =
createObject(“Quicktest.Application”)
Qtpapp.Open “C:\SampleTest1”,False,False
Set qtrep = Qtpapp. qtApp.Open
"C:\Tests\Test1", False, False ' Opens a test in qtp
Set qtRepositories = qtApp. Test.Actions(“Action1”).ObjectRepositories ‘Creates an object of repository collection i.e all repositories associated with a test action
Set qtRepositories = qtApp. Test.Actions(“Action1”).ObjectRepositories ‘Creates an object of repository collection i.e all repositories associated with a test action
If qtRepositories.Find(“C:\ORTest.tsr”) = -1
Then ‘If OR is already associated with a test, do nothing else add the required
shared object repository.
qtRepositories.Add “C:\ORTest.tsr”, 1
End If
Question 6: Can we stop a test execution through AOM?
Answer: Yes, we can stop a test from AOM, but
the question arises, why do stop test from AOM when we can stop a test using
exitTest statement. Many a times,exit statement does not work in QTP 11 when
the exit statement was called from inside functions called from function in vbs
library. In case exitTest statement does not work we can exit a test using
below code:
Set qtAppObj =
CreateObject("quicktest.application")
qtAppObj.Test.Stop
Question 7:
Which of the following method of recovery object is used to activate recovery
scenario through AOM?
a.
Activate
b.
Add
c.
Enabled
d.
Focus
Answer: we
can enable a recovery scenario using enabled method of recovery object.
Question 8: How can we connect to ALM using VBScript?
Answer: Using
the below code, we can connect to ALM through VBScript using QuickTest
Application object as shown below:
Set qtApp = CreateObject ("QuickTest.Application")
If
qtApp.launched <> True then
qtApp.Launch
End If
qtApp.Visible = "true"
If Not qtApp.TDConnection.IsConnected Then
qtApp.TDConnection.Connect
QCurl, DomainName, ProjectName, UserName, Password, False
End If
