iterating through 2 data sets
Hi,
I'm having problems with a while loop within a while loop, doing the
following (written in pseudocode):
String header, url;
header = readFromCSV(file1);
url = readFromCSV(file2);
while (header != "<EOF>")
{
while (url != "<EOF>")
{
HTTPRequest(header, url);
}
}
Is there any way to do something equivalent in JMeter? I currently
cannot get it to loop through all the urls and all the headers. Am I
missing something?
Thanks,
Simon

I should also have said - I don't know how many urls/user-agents will be
in the suite necessarily, as the suite is being constantly updated. Is
there any way to loop through the files with an unknown number of
urls/user-agents?
Thanks
Simon

Still does not work, because the url will remain set to <EOF> once
reached as there is nothing to change it.
As I said, JMeter cannot reset the file back to the beginning, so you
need to work round this - see my suggestions.
It might help to know what you are trying to test - perhaps there is a
better way of coding it.

No, I'm not.
The loop would not work in Java either - once you have reached
url=<EOF>, it stays there.
What is different about JMeter is that it is difficult/impossible to
reset the file reader.

Yes, see my earlier posting as to how you can get round the JMeter
file reset limitation.

RE: iterating through 2 data sets
Posted by Simon Brown <Si...@openwave.com>.
Hi Sebb,
So basically what you're saying is that the while loop in JMeter doesn't
work like a conventional while loop in for e.g. Java?
I'm doing a regression test on a suite of urls with different
user-agents. I want to send a request to each url for all the
user-agents. Both the url and user-agent lists are stored in csv files.
Any suggestions?
Thanks,
Simon

RE: iterating through 2 data sets

Hi Sebb,
Many thanks for your response. Sorry - I made a mistake in the
pseudocode - for every url in file 2 there should be a request made for
every header in file 1!
It should be:
String header, url;
header = readFromCSV(file1);
url = readFromCSV(file2);
while (header != "<EOF>")
{
while (url != "<EOF>")
{
HTTPRequest(header, url);
url = readFromCSV(file2);
}
header = readFromCSV(file1);
}
Regards,
Simon

It looks as though the header and url are only read once.
Also presumably the url loop needs to be reset for each header?
It's not possible to "reset" a file reader in JMeter, though you can
loop through a file repeatedly. If you know how many entries there are
(or what the last one is) you can construct a loop around that.
BTW, the Java Request sampler is good for testing - it does not need a
server, and you can include any variable names you like in the label
or response data etc.
