Question

I’m trying to load test a WCF REST service.
The service takes a single parameter and returns an page.
I’d like to pass multiple of this single parameters.

Example :

server:8080/service/?id=1   
server:8080/service/?id=2  
server:8080/service/?id=3  
server:8080/service/?id=4  
server:8080/service/?id=5  
server:8080/service/?id=6  
......    

How do I do that?
Any ideas?

Answer 1

Take a look to Loop controller and Counter, if you still have doubts place me a comment.

UPDATE

Your response didn’t sound polite.
Anyway, what about this – CSV data config?

You can put there arbitrary data.

It works for me, here is the JMeter Project.
Put the CSV file in c:\tmp\data.csv with these three lines as content

1
2
3

to get these calls:

http://localhost:81/index.php?id=1
http://localhost:81/index.php?id=2
http://localhost:81/index.php?id=3
