hi raghav,
i have a post http request (create product), the data uploaded as json file to the http sampler ( not as body), and i want to repeat this request in the same iteration ( creating 10 products for example), the problem is that i receive an error response "product already exist" plz advise how we can handle this problem.

Hi Raghav, I have a test scenario for validate the email address.For that I create a csv which contain multiple email address in different format.I added this using file through the csv data config. Is there any way to add assertion for each row of the csv?because I need fully automate that test and get only the pass/fail status.

[slobodanparizoski]

So basically, the While controller checks: while(variable exists == true)...execute sampler. And the CSV data config is taking care on every new step, new line to be checked?

Hi Ragha, I want to import TX id which are in CSV file more than 2500 Txs. And those are used as a restApi. Those should be thread safe while executing and as I don't know how much time it will take so no value for rampup. And every thread should take unique value.
Is it possible?How to do?

Hi Raghav, I'm using JMeter for functional (API) test for my iOS App. When login to the App, there are several records (rows). User can tap any of the row. I want to tap each and every record (row). Is there a way to do this?

Hi Raghav,
Here you have shown how to fetch data from multiple rows from CSV for a single request. In my case I want multiple request, lets say 6 request to fetch data from 6 different rows with columns containing around 10-12 parameters. How do I achieve this ? Please help me out on this.

[gayatritankar]

Hello sir, How can I pass the parameter for a quiz where multiple users can play the same quiz simultaneously through JMeter(I am testing APIs)? I made a CSV file for login credentials, when I tried to run it in JMeter it worked fine. After that, I created another CSV file for contest-id, and trying to run it's not working because here I have passed a specific user Token. I don't understand how can I pass multiple tokens to multiple users. Could you please reply? This quiz is like a mcq question. Also, how can we select different answers for multiple users? Can we add more CSV file in a single Thread? Please reply.
