How to make requests that depends on responses


Hi all.

Is there a way (with Grinder 3) to make that my requests  depends on the 
response? I will make an example:

Supose that when I make a request the server gives me one list of, for example, 
cars, and I want to edit the information of one, but I don't know its ID, so I 
have to look into the response and look for it. Can I do that? Is there an 
example that could help me??

Thanks a lot.

Carlos

HTTP Response CODE

Hi all.

If I understand well, errors in data logs are Java errors, not HTTP errors 
(like, for example, 401 or 500). Is there a way to make that data logs send 
(like they do with Thread, Run, Test, Transaction time, Errors) the HTTP Code 
of the response?

Thanks a lot.

Carlos

Hi,

Do we have to set some options or something for Junit Plugin to Grinder 3.0.
When we plugged in the Junit test cases, it's saying that ".py" not available.

Herewith am attaching the properties file i used to run. The error shown is "grinder.py" is missing or cannot be read.



Pls address this query as early as possible

Regards,
Chitra

adding to cart

hi,

i can't see why during a scenario (captured by the
tcpsniffer) which consists of logging then adding
object to cart for 100 simultaneous users, there is no
change in the cart content. In other words, during
grinder-use, if i log in to the online application and
see the cart content, i expect to find at least 3, 60
or 100 of that object in the shopping cart.

Thank you for your help

Problem with grinder-3.0-beta8...

Hi !
I am having a problem with grinder-3.0-beta8...
Running on a Dell Inspiron 7500 laptop with 384MB Memory (Celeron 466)
under the Window 2000 Server operating system.
After adding grinder.jar to my classpath,
I kick off the Console via net.grinder.Console
then kick off the Grinder via net.grinder.Grinder
Then via the sample hello-world.py script, the Grinder runs the 10 
tests, but the TPS figure keeps changing,
and the Console command window keeps throwing out the following 
exception at about 1 second intervals:
java.lang.NoClassDefFoundError
        at net.grinder.console.swingui.ConsoleUI.updateStateLabel
(ConsoleUI.java:442)
        at net.grinder.console.swingui.ConsoleUI.update

I doubt it. I use 2K professional with no problems (modulo multicast
issues).

Is anyone else using The Grinder with XP? Has anyone seen behaviour

Unfortunately I slipped up for beta 8 and introduced a dependency on
the new colour constants in JDK 1.4.1. This will be rectified in the
next beta. In the meantime, please either use JDK 141 or regress to
beta 7.

cookies


Are cookies returned by the response on test1 sent by the
request for test2 automatically? The script I'm trying to 
run is:

grinder.plugin.parameter.followRedirects=true

grinder.test1.parameter.url=http://gagel.rf.rabobank.nl/webapp/examples/ping
grinder.test1.parameter.header.host=gagel.rf.rabobank.nl

grinder.test2.parameter.url=http://gagel.rf.rabobank.nl/webapp/examples/j_security_check
grinder.test2.parameter.post=D:/programs/grinder-2.8.6/examples/http/http-plugin-sniffer-post-5
grinder.test2.parameter.header.host=gagel.rf.rabobank.nl
grinder.test2.parameter.ok=Ping

I'm using 2.8.6 to test WebSphere Application Server.

Thanks in advance,

Gert-Jan van de Streek
