I need to run concurrency test on website. I need to check various parameters such as response time, request send to site, data received, and whether the data is received correctly (e.g. if multiple users log into the site, are the data displayed for user). The data of one user should not be displayed to any other user. How do I do automation for such a scenario?
I have checked JMeter and Blaze meter but done with concurrency testing it has multiple user, request, response time, not no way to check concurrency.
For example, suppose user "A" logs into the website but after logging into site he see details of person "B" so is there anyway to check this scenario? I am using all open source tools for testing, such as selenium,jmeter, java etc.
