Is VB Script Supports OOPS Concept . . .

My answer for this is No but Yes.
To supports the OOPs concept, the script needs to be satisfy the OOPs principles.

OOPS Principles -
1.Encapsulation
2.Inheritance
3.Polymorphism

Lets write a script to satisfy each principle -

Encapsulation - The wrapping of data and function into a single unit (Called class) is known as Encapsulation.

Example -

Class Maths

Function add(a,b)
MsgBox "Sum = "&a+b
End Function
End Class

Set Mat=New Maths
res=Mat.add (2,3)

'************************************************************************************

Inheritance - It is the process by which object of one class acquire the properties of object of another class.

'Example -

Class Outer
Function test()
Set inn= New Inner
inn.display
End Function

End Class

Class Inner
Function display()
MsgBox "This is inner class"
End Function
End Class

Set out=New Outer
out.test()

'************************************************************************************

'Polymorphism - Polymorphism means the ability to take more than one form/methods

Example -

Dim idno, name, marks
Class Student

Function SetData()
idno="10"
name="arun"
marks="300"
End Function

Function getData()
MsgBox "Idno "&idno
MsgBox "Name "&name
MsgBox "Marks "&marks
End Function

End Class

Class Student2

Function SetData(a,s,m)
idno=a
name=s
marks=m
End Function

End Class

Set Std1=New Student
std1.SetData()
std1.getData()
Set std2=New Student2
std2.SetData "12","Singh","400"
std1.getData()


I am trying to say Yes, it supports OOPS concept. But if any body is having any questions or my assumption is wrong then please post here as a comments.

How To Run QTP Scripts at Scheduled Time?

I have gathered this information from learnqtp.com by Ankur.

There can be situations when you need to schedule your QTP scripts so that they can run when you are not present in front of you PC. I will show you a demo below -
1) Create a .vbs fild to launch QTP with requiresd settings, add-ins etc.\\
Here is a sample vbs code

Set App = CreateObject("QuickTest.Application")

App.Launch

App.Visible = True

App.WindowState = "Maximized"

App.ActivateView "ExpertView"

App.open "C:\Program Files\Mercury Interactive

\QuickTest Professional\Tests\Test1", False

'Opens the test in editable mode

2) OK, for the first timers. Create a sample QTP test and save it as Test1 at the location above. Copy the code into notepad and name the file as testing.vbs

3) Now we will automate the opening of vbs file through windows scheduyler. Go to Start > Control Panel > Schedule Tasks > Click Add Schedule Tasks Click Next on the Screen

4) Click Browse and select the .vbs file you just created. You will ge this screen.

5) Give a name to the task and select the frequence for performing the
given tasks. For this demo we will select "One time only"



6) Select Start Time and Start Date. For this demo, select Start Time as current time+5 mins and Start date as today date.
7) Next Screen Enter "UserNAme", "Password" and "Confirm Password"
Click Next and you should get this screen.













8) Click on Finish, you're done.

Environment Variables

Environment variables in QTP are like global variables in other programming languages which can be accessed through any part of the script. The values of these variables remains same irrespective of the number of iterations (unless you change them through scripting). These variables can prove to be very useful when you want a variable to be shared across various reusable actions.

There are two types of environment variables:

1. Built-In: These are the internal variables that are provided by QTP. Among others they can provide you valuable information like the path of the folder where test is located, the path of the results folder, the name of the action iteration or the OS version. So, how can we access the built in environment variable? It’s simple, just have a look at screenshot. So if you want to know the OSVersion of the operating system where your test is running. You can simply type in Environment.Value(“OSVersion”)
2. User-Defined: These can be further defined into two types.
   • User defined Internal
     • These are the variables that we define within the test.
     • These variables are saved with the test and are accessible only within the test in which they were defined.
     • So how can we define and use them?
       To define them: Environment.Value(”name”)= “Rajaputra”
       To call them: msgbox Environment.Value(”name”)
   • User defined External
     • These are the variables that we predefine in the active external environment variables file.
     • These can be created using a list of variable-value pairs in an external file in .xml format. This is a topic of a separate post that we will discuss later.
   
   

   We can use environment variables in a number of ways:

   1) When you want a global variable that is needed throughout the test run (across all your reusable actions).

   2) When you see that one reusable action in a script is dependent on the others. You might want to use them

   3) When you need to reference the current “test directory” irrespective of the location where it is stored.

How to use Classes in QTP

Here i am giving an useful information about how to use classes in QTP.

Before going to that we will discuss about using functions in QTP.

If there is a function in our script like this

'*********** ********* ********* ********* ********* ********* **
Function Demo(a,b)
demo=a+b
End Function
'*********** ********* ********* ********* ********* ********* **

This is a function to add two numbers.
To call this function we write
'*********** ********* *****
val=demo(2,3)
msgbox val
'*********** ********* *****
We can store the functions in library files (.vbs) and to use this function, Library should be associated to the QTP Test or library file should be executed by QTP Test using ExecuteFile statement.
This means we can use the functions which are written in QTP Script or in Library files by associating it or by executing it.

But this is not possible when using classes in our QTP Test. If we want to use a class which is there in the libraryfile its mandotory that the library should be executed using Executefile statement.
Classes will not work which are there in associated libraries. Here is an example...

'*********** ********* ********* ********* ********* **
Class Maths
Function Add1(a,b)
add1=a+b
End Function

Function sub1(a,b)
sub1=a-b
End Function

End Class
'*********** ********* ********* ********* ********* **
If the above code is there with in the test script then the usage of this class will be like this
'*********** ********* ********* ********* ********* **
Set mat=New Maths
val=mat.add1( 2,3)
msgbox val
'*********** ********* ********* ********* ********* **
If the class code is there with in the library file then the usage of this class will be like this
'*********** ********* ********* ********* ********* **
ExecuteFile (Library Path)
Set mat=New Maths
val=mat.add1( 2,3)
msgbox val
'*********** ********* ********* ********* ********* **
This class will not work If you just associate the library with in the
File--> Settings --> Resources
But there is a way of using the classes even though if it is in associated library.

First Method:
Where ever the class is declared in the library it self create the class instance and use it in your qtp script.
'*********** ********* ********* ********* ********* **
Set mat=New Maths

Class Maths
Function Add1(a,b)
add1=a+b
End Function

Function sub1(a,b)
sub1=a-b
End Function

End Class
'*********** ********* ********* ********* ********* **
To Use this class
'*********** ********* *
val=mat.add1( 2,3)
msgbox val
'*********** ********* *

Second Method:
Create a function which is returning class object by creating instance of the class.
'*********** ********* ********* ********* ********* **
Function mat()
Set mat=New Maths
End Function

Class Maths
Function Add1(a,b)
add1=a+b
End Function

Function sub1(a,b)
sub1=a-b
End Function

End Class
'*********** ********* ********* ********* ********* **
To Use this class
'*********** ********* *
Set mth=mat ' mat is a function which will return the class instance
val=mth.add1( 2,3)
msgbox val
'*********** ********* *
