Jmeter CSV data config element not working

Question

I have created jmeter script for load testing and added CSV data element to read Username and Password of 300 Users.Also followed below steps;

• Created CSV file using a notepad and stored it in a directory where created script stored.
• Defined variables and file path in CSV data set element
• Used variables as parameters of HTTP request
• Increased number of Threads

But it doesn't worked as expected.How can i fix this?

Answer 1

Temporary reduce threads count to 1-2, add View Results Tree listener and inspect request and response details.

If don't see proper username/password combination in the request body - your script is misconfigured. Check out Using CSV DATA SET CONFIG guide for detailed setup instructions.

If you see valid username/password pair but login is not successful, follow below checklist:

1. Add HTTP Cookie Manager to your test plan
2. If point 1 doesn't help - check for dynamic request parameters. Probably you'll need to extract some value from the first response (when you execute GET request for the login page) with the Regular Expression Extractor, convert it into a JMeter Variable and add it as a parameter to the request which performs login.
