Parametrization in JMeter -2

Method2 Using preprocessor (User Parameter)

For a parameterization using CSV Config Element please read my previous post – Parameterization in Jmeter-1.


1. To parameterize a login scenario for more than one user first record the login scenario.

2. Open a notepad and enter userid and password for three users.

Save the file as test.csv. The extension csv makes it a comma separated Value (CSV) file.


3. Select the Login sample and add a “User Parameter” element to it.

Add->Preprocessor-> User parameters


In parameters add three variables and fill it as shown in below figure:


__CSVRead is a function which reads values from file test.csv . The second parameter of the function is the column number .Name is the variable name which is referenced in the request sample.


Now select the login sample and change the values of userid and password to ${A} and ${B}.


You can also generate the value for variable using function helper dialog. Open it from options or use shortcuts ctr+F. Choose __CSVRead from choose a function dropdown list. The value field of first row in the Function parameters represents the file name (here test.csv) and second row represents column number (e.g. 0, 1, 2…).

Now run the script and observe the result in view result tree.
