quick and dirty explanation. Load test means load as many users as possible before the system crashes - you start with 50 and add users until the system stops responding or the response time is completely unacceptable. Stress testing is playing back a number of users for x period of time to see if the system crashes or the response time is completely unacceptable. What you are trying to find out with a stress test is are there any memory leaks what happens when I ask the system to do the same thing continuously for a period of time. LoadTest you are trying to find out the number of users the system can handle.
could any one exactly outline the differences between load test and
stress test....I am not sure whether this question has been answered
