Class ParamModifier

  • All Implemented Interfaces:
    Serializable, Cloneable, Searchable, PreProcessor, TestElement, TestStateListener

    public class ParamModifier
    extends AbstractTestElement
    implements TestStateListener, PreProcessor, Serializable
    This modifier will replace any single http sampler's url parameter value with a value from a given range - thereby "masking" the value set in the http sampler. The parameter names must match exactly, and the parameter value must be preset to "*" to diferentiate between duplicate parameter names.

    For example, if you set up the modifier with a lower bound of 1, an upper bound of 10, and an increment of 2, and run the loop 12 times, the parameter will have the following values (one per loop): 1, 3, 5, 7, 9, 1, 3, 5, 7, 9, 1, 3

    The ParamMask object contains most of the logic for stepping through this loop. You can make large modifications to this modifier's behaviour by changing one or two method implementations there.

      • testStarted

        public void testStarted()
        Description copied from interface: TestStateListener

        Called just before the start of the test from the main engine thread. This is before the test elements are cloned. Note that not all the test variables will have been set up at this point.

        N.B. testStarted() and testEnded() are called from different threads.

        Specified by:
        testStarted in interface TestStateListener
        See Also:
        StandardJMeterEngine.run()
      • testStarted

        public void testStarted​(String host)
        Description copied from interface: TestStateListener

        Called just before the start of the test from the main engine thread. This is before the test elements are cloned. Note that not all the test variables will have been set up at this point.

        N.B. testStarted() and testEnded() are called from different threads.

        Specified by:
        testStarted in interface TestStateListener
        Parameters:
        host - name of host
        See Also:
        StandardJMeterEngine.run()
      • testEnded

        public void testEnded()
        Description copied from interface: TestStateListener

        Called once for all threads after the end of a test. This will use the same element instances as at the start of the test.

        N.B. testStarted() and testEnded() are called from different threads.

        Specified by:
        testEnded in interface TestStateListener

      • testEnded

        public void testEnded​(String host)
        Description copied from interface: TestStateListener

        Called once for all threads after the end of a test. This will use the same element instances as at the start of the test.

        N.B. testStarted() and testEnded() are called from different threads.

        Specified by:
        testEnded in interface TestStateListener
        Parameters:
        host - name of host

      • process

        public void process()
        Modifies an entry object to replace the value of any url parameter that matches a defined mask.
        Specified by:
        process in interface PreProcessor
