java.lang.Object org.apache.jmeter.testelement.AbstractTestElement org.apache.jmeter.protocol.http.modifier.ParamModifier
public class ParamModifier
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.

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.
