performance testing - load test with varying number of threads in JMeter -


i have been exploring jmeter last couple of days. , try achieve following: trying create load test service such that, in first loop 'n' threads created , in second loop 'n+m' threads created , in third loop 'n+2m' threads, in fourth 'n+3m' threads , on. did find many solutions here , tried replicating them, somehow not working me. test plan created looks this:

step 1: add user defined variable called usercount = 0

enter image description here

step 2: create thread group. have used __intsum increment usercount 1 , storing result in usercount future reference.

enter image description here ideally expecting here is, in first loop 1 thread created, in second loop 2 thread created , in third loop 3 threads created. in total there should 6 thread created. results show this: enter image description here

not sure if missing silly or approach wrong. community appreciated. :)

i believe trying impossible. when jmeter starts thread group first time initializes number of threads.

what trying re-run same test 3 times different numbers of users each time. jmeter cannot re-run thread group once started, can re-run ("loop") thread in thread group. not possible add threads running thread group once ramp , threads initialized. (let me know if should try explain further).

if want 1 thread group populate run-time settings of thread group, must have 2 thread groups in test plan. @ test plan level, check off option "run thread groups sequentially."

with option, jmeter not initialize number of threads on second thread group until first 1 finishes. first thread group can set global property, , second thread group can reference in number of threads.

how set property in beanshell: (this in thread group 1)

props.put("threadgroup_2_num_users","15");

how reference value in thread group 2:

${__p(threadgroup_2_num_users)}

if not help, maybe try describe end goal. trying learn thing testing?

edit: perhaps using plugin package "stepping thread group" allow achieve scenario trying in single thread group. check out: http://jmeter-plugins.org/wiki/steppingthreadgroup/

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
