1. Introduction To ‘Parameterization’

2. Parameterization
Parameterization is used to change the value of any variable at run time.

3. Following can be parameterized in a script file:-
URL portion
Header portion
BODY portion

4. How is parameterization done?
Parameterization is done through NetStorm variables (NS Variables).
 There are different kinds of NetStorm variables.
Different variables are initialized in different way.
Declaration of different variables is also different and they are used for different work.
NS Variable value is accessed by putting it’s name within curly braces ({}).

5. Steps to be followed through GUI
1.Go to Login page of NetStorm machine

6. Login using your credentials. NetStorm dashborad will open.

7. Go to Test Scripts tab and click on Launch Script Manager
Go to Test Scripts tab and click on Launch Script Manager. This will launch Script Manager.

8. Open the script

9. If script is recorded in Legacy Mode, then parameterization will be done in script.capture file.
If script is recorded in C Mode then parameterization will be done in registration.spec. file

10. After selecting the appropriate file ,go through the following procedure.
Click on File > Parameters.
(Various parameters will be available here, choose the one as per your requirement.)

11. Also you do the same work in the following manner
Right-click anywhere in the right-pane. You will get menu as shown below:-

12. NetStorm will now automatically place parameter APIs at appropriate place in the file.

13. To Parameterize URL? Format of url is as follows::
scheme://domain:port/path?query_string#fragment_id
You can parameterize any part of query_string or path of resource.

14. url can be parameterized in the following manner::
Parameterize query_string
used in a web_url () function may be parameterized using NS variable username as
Here the URL shall be modified each time using the current value of NS variable username.
Parameterize path of resource
robert
Here the URL shall be modified each time using the current value of NS variable address.

15. To Parameterize Header
Any part of HEADER can be parameterized
Example:-
HEADER=Accept-Language: en-in
used in a web_url () function may be parameterized using NS variable language as
HEADER=Accept-Language: en-in{language}
Here HEADER will be modified each time using the current value of NS variable language.

16. To Parameterize BODY Any part of BODY can be parameterized Example:-
BODY=Current Date is
used in a web_url () function may be parameterized using NS variable cur_date as
 BODY=Current Date is {cur_date}
Here BODY will be modified each time using the current value of NS variable cur_date.

17. Types of Parameters
There are 9 types of parameter. They are:-
File Parameter
Search Parameter
Declare Parameter
XML Parameter
Index File Parameter
Date Time Parameter
Random String Parameter
Random Number Parameter
Unique Number Parameter
These parameters are explained in detail in subsequent slides.
