Branching in tests
Hello.
I was trying to prepare some tests using JMeter, and its seems that
existing logic controllers are just not enough.
In my test plan, I wanted to have some branching - i.e. I wanted to
group together some test "branches" (Simple Controllers with some HTTP
Requests inside) under some ControllerX, so that for every iteration
only one of the branches will be ran with some set probability. So,
RandomController may be called a simpler version of such ControllerX -
since it also runs only one of its children, with equal probability
for all of them.
What is the easiest way to implement such a controller in JMeter? As I
can see it now, it may be either done by e.g. using additional Java
code for Java Request Sampler (which will do the random choosing) plus
Switch Controller, or writing a custom Controller as a plugin (which
is most likely much harder). But who knows - maybe it was already done
before. What could you suggest?
Regards,
Andrey

Hi all,
I just received my copy of Apache JMeter from Packt Publishing. I'll be
reviewing it for our website, www.javaperformancetuning.com and
www.theserverside.com. At 108 pages I expect I'll be finished the book
in a very short, single sitting. Not that I have anything against short
books, some of the most useful books that I've read have been short.
Does Emily happen to monitor this list? If so, it could be useful to
have some contact prior to publishing.
Regards,
Kirk Pepperdine

Switch Value: ${__BeanShell(script goes here)}
Or you can define a function in the BeanShellFunction.bshrc file and
call the function.

Re: Branching in tests

Hi,
So as I understand, the script will be something like
Random generator = new Random();
double myRandom = generator.nextDouble();
if (myRandom < 0.9) {
return 0;
} else if (myRandom < 0.95) {
return 1;
} else {
return 2;
}
instead. But where should I put my BeanShell Sampler then? Should I
add it to the Switch Controller as a child? How do I show JMeter that
the returned value should be passed to the Switch?
Regards,
Andrey

For a short script like this it might be better to use a function
which returns the value directly to the Switch Controller - i.e.
instead of "vars.put()" use "return value".
You could use BeansShell, Javascript or Jexl.

Hi,
that worked for sure - thanks for your advice! I guess Ill be using
BeanShellSampler and Processors a lot in my tests.
In my case (3 options in the Switch Controller) I just had to add a
simple BeanShell Sampler just before the Switch Controller with some
very simple Java code
Random generator = new Random();
double myRandom = generator.nextDouble();
if (myRandom < 0.9) {
vars.put("REPORT_SWITCH","0");
} else if (myRandom < 0.95) {
vars.put("REPORT_SWITCH","1");
} else {
vars.put("REPORT_SWITCH","2");
}
and then use the ${REPORT_SWITCH} in the following Switch Controller.
Regards,
Andrey

I did this with a bit of beanshell to do the weighted random selection
and switch controller to do the actual switch. I'd paste the code in,
but unfortunately I can't find it at present...
