To know the answer, first let’s understand what is the important of ‘Think time’. Think Times are necessary in Performance Test Scripts to bring in realistic end user simulation. We all know that Think time is the time spend by the end user in thinking and entering the user inputs before...

If you know Little’s law, you are already very near the answer. In a closed system (performance test environment), every virtual user fires the next request only after receiving the response for previous sent request. If the system response time increases, time taken fire the next request will...
