Parameterization Using User Variables

Now we will learn how to parameterize the values using User Variables.
For this parameterization also we will use a public site as an example i.e. www.redbus.in.
Follow the following steps :
To Parameterize the Booking scenario, first record the Booking scenario.
1] Add Thread Group Recording Controller and HTTP Request.
            In HTTP Request > Server Name or IP : Enter http://www.redbus.in
2] Add a HTTP Proxy Server for the Workbench
3] Start the Proxy Server and open Mozilla Firefox and go to http://www.redbus.in.
4] After recording a few transactions, close the browser and stop the Proxy server in Jmeter. U get the below recordings.
5] Here we have seen the tickets from Mumbai to Goa on 07-Dec-2011
6] Now we will parameterize the values of fromCityName and toCityName using User Parameters.

For this do the following steps:

7] After recording the script first save it.
8] Create a new file in “text document” form in bin folder.
9] Enter the values for each thread or user in separate rows with fields separated by commas as shown in the screen shot.
10] Save the file as (file => save as) uservar.csv file in the same bin folder.
11] Now in the Apache_Jmeter   window go to Options > Function Helper Dialog
12] Create new function with function type __CSVRead.
13] In the values column for CSV file to get values from give the file name (i.e. uservar.csv) from where values are retrieved. Give the complete path incase the file is not created in bin folder. In Column number of CSV file give 0 as user ids are stored in first column and count will be started from “0”.
14] Then click on generate option to generate a function. Then copy the function string generated.

15] Now again goto Apache_Jmeter window.
Right click on thread group.
Then click on Add > Pre Processor > User Parameters to create a new userparameter.
16] The following window will be opened. Click on Add Variable tab to add a new variable.

17] Now in the name column give the name of the variable you want to replace (fromCityName) as “A” in this example and in the user_1 column paste the function string that was copied previously from the function helper window i.e., (${__CSVRead (uservar.csv, 0)}).

18] To parameterize more than one more variable then click on Add Variable. For parameterizing toCityName filed in Name field enter “B” and in User_1 column paste the generated function but change the column number to 1 i.e.,(${__CSVRead (uservar.csv,1)}).

19] After entering all the values that are to be parameterized click on Add Variable and in Name field enter “next” and in the User_1 column paste the function string and replace 0 in the string with next i.e.(${__CSVRead (testdoc.csv, next)}).
20] Find and replace the variable values that are to be parameterized with function strings.

In this example find fromCityName value and replace it with the function string that is ${A} and find toCityName value and replace It with function string ${B}.
21] Save the script and Run the Test.
22] See and Check the results with new modifications.

    1. I have explained all the recordings step by step with screen shots so that you can compare with yours and get the point where you are stuck.
      If you still not get it then let me know at which point you didn't get it.

    2. HI Mahesh,

      Could you pls let me know how do i pass variable if the URL is dynamic based on your search value? for ex: http://aa.bb.com/bikes/activa
      http://aa.bb.com/bikes/yamaha

      now the value after bikes is dynamic based on my search results and corresponding page is displayed. How do i parameterize this in Jmeter?

    1. Hi Manu,

      Please edit the csv file using notepad and make sure that the data appear coma separated.

      Its always better to edit the csv file using a notepad before making a test run.

      Hope this will solve your issues

      Regards,

      Faisel Hussain

  3. May I know as to what is the need of Step No. 19

    19] After entering all the values that are to be parameterized click on Add Variable and in Name field enter “next” and in the User_1 column paste the function string and replace 0 in the string with next i.e.(${__CSVRead (testdoc.csv, next)}).

    We already added the parameters that we need as A and B.

    @Manu, have you tried using Update once per iteration and see if it picks up second row from csv file.

    1. Hi,

      I have tried the above steps but when I am using user and password as the variable name and parametrizing these two variable I cannot see the values being reflected in Request tab after running the application.
      And the values are as following.

      user ADMIN false true
      hidRequired user false true
      hidInputBoxName user false true
      label User Name true true
      password 6474113d763f7b6f2561be711ec114e2806e3535b0d5a9418b72a59a1cc38e2165349b7a6847db2c0946891f9d1fa7c6ddd657fd014ccdeee06f3731b16610832fff828af80cd72cd8e5de77575164e47fb3ae9bba0b84d44eee1757c7c4dda682ebbbfb26dbfdcc0a1eb800000 false true
      hidRequired false true
      hidInputBoxName password false true
      label Password false true
      isSkip false false true
      bt_Login Submit false true
      conId false true
      newCon true false true
      browserType IE false true
      applicationType BuildNPlay false true
      screenHeight 1024 false true
      isFromAlternate true false true
      tmpChk cd3fed8af7c70312d5abc60589e435e29c1b6e768fcd300106d26fd8c9db4b3f false true

      I was using user and password as the variable name.

  4. I was able to do the parametrized, BUT the problem is that its NOT picking up the data row wise, also its mixing up the data, I have 2 values in single row, each row is set of data, here the data sets are getting mixed up..why?

    ReplyDelete
  5. There are easier ways to do this.
    1- Create data file (txt or CSV) , include values only (have each column separeted by coma)
    2- Add Configuration Element - CSV data set config
    3- In file name enter file path (including filename and extension)
    4- In variable names add the variables you will use (one for each column, separate with coma)
    5- replace the data to parametrize using ${variable name}
