How to do Parameterization using
TrueClient Protocol?

Parameterization is passing different values for each virtual user or iteration.
When you record an application using true client protocol in Loadrunner, the
script contains values such as username, password, account number etc.
Suppose if you want to pass different username, password and account
numbers for each iteration that login into the application, then you can use
parameterization.
What is Parameterization?

Steps to create Parameterization in Trueclient script:-
As we can see on below image, User is registering on Website with his personal
phone number. But in real time there will be number of users who will be
registering with their unique personal details including phone number, name,
address etc. So in that we case, we need to parameterize those value in our true
client script.
So let’s start with this approach which is very simple. As shown in below
screenshot, Select the value which you want to parameterize let’s say phone
number (See highlighted field below).

Expand the steps as shown below. Go to
Arguments.

Select the value as a type of Java script value.
Icon Type
Literal string
JavaScript value
Parameter

Figure 1.3: Select JS in Parameter type.

Figure 1.4: Diagram showing type JS selected in parameter.

Right-click and select Replace with a Parameter.
Figure 1.5:Right click and select ‘Create new parameter for selection’.

In the Enter Parameter Name dialog box, enter the parameter name.
If the parameter does not exist in the Parameter List, it is created and the
default parameter type is set to File.
You can go to the Parameter List to add or delete values for the specified
parameter.
By default, the original value is included in the list of values for the

Figure 1.6: provide parameter name and confirm.

Once you click on Ok, it will create a JS function TC.getParam(“Phonenumber”)
in value. You can also type this JS function in value tab and select parameter type
as JS.
Figure 1.7: After confirming JS code in value will be displayed as
TC.getParam(“PhoneNumber”); .

Figure 1.8: Go to parameters > change the value as per the test.
As You can see Parameterization is done using trueclient protocol in loadrunner.
