1. Thread Groups:   To start building the test script, we need to add a Thread Group. Thread groups determine the user flow and simulate how users behave on the app. Each thread represents a user. In layman’s words, Thread group allows us to design the execution process of performance testing like how many users, no of iterations, Type of Thread Groups: -          Thread group -          setUp Thread Group -          Tear Down Thread group -          Stepping Thread Group (plugin in Jmeter) -          Ultimate Thread Group   (plugin in Jmeter) 1.        Thread Group : this is basic type of group provided by JMeter with simple load test configuration. We can you this group if we want execute test like only loop, but we c...

                      Virtual User Concept in Performance testing As i have defined "Concurrent user" in one of my post before, but this is one of the important concept which need a good grasp for a performance tester. Let me again re-phrase the user concepts in terms of performance testing: User can be termed as "Virtual User" in performance testing perspective since during the test run , users used are not the real users. Virtual users can categorized into various types in terms of understanding, but " Simultaneous Users " and " Concurrent Users " are widely used as concept in testing. What is Simultaneous Users? The users who have a valid session in the server. Each of the users would be performing different actions like one doing login , other viewing the reports, etc. What is Concurrent Users? The users who have a valid session in the server & they are performing the same operation at any poi...
