Hello,
I didn't use counter.
This is my last test sequence:
-- http request sampler reading the list of pages
|--> child: regex extractor to extract the total of pages, into a
variable numPageMaxi
-- while controller: ${__javaScript( ${i} < ${numPageMaxi} )}
|--> child 1: http request sampler to turn to the next (it takes
parameters like ${__javaScript(${i} * 50)}, ${__javaScript(${i} * 50 +
50)}, for lower bound and upper bound)
|--> regex extractor to parse <tr> elements into an array:
htmlResponse
|--> child 2: foreach controller on ${htmlResponse}
|--> http request sampler that sends extracted <tr> elements
to a remote server
|--> child 3: BeanShell Post Processor that increments my own counter
variable i, with the following code:
String i = vars.get("i");
int counter = Integer.parseInt(i);
counter++;
vars.put("i", "" + counter);
My BeanShell Postprocessor is a child of the while() controller that runs
over the 2 pages, and not of the foreach() controller that runs over <tr>
elements of each page.
However even if I put the postprocessor in front of foreach(), my scenario
yields still the wrong results (it takes the foreach()'s upper bound as my
${i}'s upper bound.
I will try Counter instead of my own variable incremented by beanshell and
see if it works better.
