Combination of 'Random' and 'Counter' Functions in JMeter

Scenario:

There is a Unique Random value in input. It is there in 2 places of same input and in both places the value is same. But this value should be unique in each and every iteration

Ex: -- Input:  theinputforapplicationtesting456879hastworandomvalues456879   -- 1^st iteration

          Input:  theinputforapplicationtesting367705hastworandomvalues367705  --  2^nd iteration

JMeter Implementation:  (I used 2 functions for this implementation and a CSV Data set)

Step 1:

I have collected all the inputs in a file and i have replaced the random value with coma ( , ) 

theinputforapplicationtesting456879hastworandomvalues456879

theinputforapplicationtesting367705hastworandomvalues367705

After replacing random value with coma it looks as below:

  theinputforapplicationtesting,hastworandomvalues,

  theinputforapplicationtesting,hastworandomvalues,

 

For these values, I have defined the variables as v1 and v2 in CSV Data set with the coma as a delimiter

Step 2:

Function 1: _Random

Ex:

${__Random(11111,99999,)}

Add User Defined variables to JMeter (Right click on Thread Group --> Add --> Config Element --> User Defined Variables)

Use this function value in User Defined variable

Ex:

Name	Value	Description
CN	${__Random(11111,99999,)}	Random Control Number

Need to use this variable (CN) in the script

 Step 3:

Function 2: _Counter 

Ex:

${__counter(TRUE,)}

Provide this function in the script along with the variable defined in user defined variables for Random function

Ex:

${V1}${CN}${__counter(TRUE,)} ${V2}${CN}${__counter(TRUE,)}

Note:

Instead of using the function  _Counter , we can also use the Config Element ‘Counter’. Both are same.
