Parameterization and Correlation are two major concepts in
modifying scripts in VuGen.
Parameterization:- It is used to run an application with
different values. Parameterization is generally done to
test with multiple set of data or records.
In this we need to select two things
1. Select next row
2. Update value on
Select Next row: It can be sequential, random and Unique
Update value on : It can be Each Occurance, Each Iteration,
Once.
COrrelation:- It takes the server dynamic values and keep
it as an array and use it as parameterization. Correlation
is used when we are facing problem like we are getting some
dynmically generating values from the server.
Two ways to do it
Manaul Correlation
Automatic Correlation
In both the Correlation the syntax woule be
web_reg_save_param("{paramname}","LB=","RB=","Ord=All","Search=Body",LAST);
Still you need to understand how this need to be done ok.
