QTP Environment Variables Simplified ~ All About Automation Testing

Share This Post -

The variables that are commonly used across the environment in many tests by different resources are know as Environment Variables.

There are Two types of Environment variables

1. Built-in-variables

2. User Defined Variables

1.Built-in-variables :- These variables will be by default available in every test and can be directly used in any test with help of following syntax.

Syntax: Environment.value(“Built-in-variables”)

Example :

var=environment.Value("OS") : to display the Operating System

msgbox var

2. User Defined Variables :- The variables which are required commonly in number of test apart from the Built-in-variables need to be created by the user which are known as User Defined Variables.

User Defined Variables are created in environment file, any body in that environment can Associate this file and use the variables in it.

There are Two types of User Defined Variables:

i. Internal User Defined Variables : These Variables are used in the same file. See below example:

Open the Cal application
Put the tool under recording mode
Capture the objects properties of Cal application to Object Repository
Stop recording

Steps for Declaring the Environment Variables in QTP:

Activate the menu item Test
Go to Settings
Select the Environment tab
Select variable type as User-defined
Click on New button
Add new Environment window will appear
Give the details of Name and value ( type will be Internal )
Click on OK
Again Click on New button to add one more variable
Add new Environment window will appear
Give the details of Name and value ( type will be Internal )
Click on OK
Click on Apply
Click on OK
If you want you can Export these data to a a file with .xml extension file in the Environment folder

Associating the Environment Variables ( by parameterizing )

Develop the script in test pane as below:

' Setting the declered environment value (a ) to value1 edit button

VbWindow("Form1").VbEdit("val1").Set environment.Value("a")

' Setting the declered environment value (b ) to value2 edit button

VbWindow("Form1").VbEdit("val2").Set environment.Value("b")

' clicking on ADD button

VbWindow("Form1").VbButton("ADD").Click

Run the test
Analyze the results

ii. External User Defined Variables :- which are Imported from other file. See below example (Proceed step by step):

Open the Cal application
Put the tool under recording mode
Capture the objects properties of Cal application to Object Repository
Stop recording

Declaring the Environment Variables:

Activate the menu item Test
Go to Settings
Select the Environment tab
Select variable type as User-defined
Select the check box of ‘load variables and values from an external file’

If you want you can make use of Exported data or you can create your own data in a file with .xml extention file in the Environment folder

Browse that file
Click on Apply
Click on OK
