    Re: I need some examples

    What do you mean by "examples"?
    Do you mean definitions?

    Have you looked through the forum here? If so, did you find any examples?

    Load,stress testing are part of the general term performance testing.

    A load test would involve running a test to check various aspects of an application like Page Response Time, Data retrieval Time, CPU usage etc for more than one user
    This test can be single test or a combination of various test cases. Gradually the user load is increased depending on the criterion specified.
    At every increase of the the user load the parameters under observation are stored. This cycle continues upto the maximum user load specified.
    The results of the test would indicate the performance of the system under various user load conditions. The data obtained for the parameters under observation
    could be compared with the optimum values of those parameters and hence the optimum user load can be obtained where the system gives maximum performance.

    Stress test is an extension of load test. A load test becomes a stress test when user load put on the system is more than the maximum user load the system can handle.
    This test would check whether the system would exit gracefully or crash or stop responding leading to system crash when such a condition occurs.

    These type of tests are very common for websites which expect an exponential surge in the user load at any time.
    e.g A famous shopping site brings an offer of 50% discount on all items. Usually the site handles 100 per hour however due to the offer a no of users htting the site
    has increased exponentially to 1000 per hour. The site can handle the same no of users per hour as its maximum load.
    In such a condition the site would stop responding to the users thus resulting in bad user experience and loss of goodwill to the company.
    To avoid such conditions stress testing is done to determine the max load a site can handle. If that is identified in the testing phase preventive steps could be taken
    to avoid such a condition when the website is exposed to real users.

    Here are a couple of references - maybe they will help. Neither of these are "authoritative" in the sense that lots of folks use these terms differently. That said, I *believe* they are useful and consistent with common usage among the thought-leaders in the area of Performance Testing.

    If you can see it in your mind...
    you will find it in your life.
