How to load a single SOAP Request with multiple authentication in Jmeter

Question

I am very new to Jmeter and need to perform a load testing of one SOAP request with 100 Authentication data. I tried the below approach, where I saved the authentication data in CSV file, using CSV Data Config parameterised and passed onto HTTP Authorisation Manager. I am able to sequentially test the SOAP request with all the user authentication data available in CSV, but I need to run concurrently, with all the 100 users. Thanks in advance.

I have 5 users authentication(username/password) in csv file

Answer 1

Set your Number of Threads to 100, and the Loop Count to 1.

Number of Threads has to do with the number of concurrent users that get run.

Loop Count has to do with how many times a user actually does your script.

Note that if your ramp-up is slower than your script time, some users will finish before your test reaches its full concurrency. Check this question for use with the scheduler.

Answer 2

In order to make all the requests to fire at the same time you need to add Synchronizing Timer to your test plan.

1. Increase "Number of Threads" to 100 on Thread Group level
2. Add Synchronizing Timer as a child of the SOAP/XML-RPC Request
3. Set "Number of Simultaneous Users to Group by" to 100

4. Make sure that CSV Data Set Config has following configuration:

   • "Recycle on EOF?" - true
   • "Stop thread on EOF?" - false

Thanks everyone for the quick answer. With the synchronizing timer had to modify "Sharing mode" option to "Current Thread Group" in http://jmeter.apache.org/usermanual/component_reference.html#CSV_Data_Set_Config.
