Hi all,
I'm new to JMeter, and also very new to Beanshell. I have to test a web
application that presents auctions where some users can place bids (something
like ebay). I'd like to save the value of the bids that each user placed. I
wanted to do this in this way:
1. My test plan tree looks like this (I simplified it a lot no to stir the
view too much):
Test Plan (it has one User Defindef Variable: name:bidValue
value:1000)
- Thread Group (Number of threads: 20, Ramp-up period: 1000, Loop
count: 3)
- HTTP Request ( many parameters, in witch one is named BID, and
the value is ${bidValue}
- BeanShell PostProcessor
I want to place a Beanshell script in the BeanShell PostProcessor element,
which will decrement bidValue with a value of 5. So in sum, I want to do
something like this:
BID value for user 1 (JMeter thread 1) in 1st loop - is 1000
BID value for user 2 (JMeter thread 2) in 1st loop - is 995
BID value for user 3 (JMeter thread 3) in 1st loop - is 990
BID value for user 20 (JMeter thread 20) in 1st loop - is 905
BID value for user 1 (JMeter thread 1) in 2nd loop - is 900
BID value for user 2 (JMeter thread 2) in 2nd loop - is 895
BID value for user 3 (JMeter thread 3) in 2nd loop - is 890
BID value for user 20 (JMeter thread 20) in 2nd loop - is 805
End so on. Here are my questions (all of them are related to writing script in
the BeanShell PostProcessor element):
1. Can somebody explain how should I do this (what script should I)?
2. When should I fill Parameters field?
3. Do I have to import any packages in the script?
4. Am I allowed only to use those variables mentioned in JMeter documentation
(log, ctx, vars, prev, data)?
5. What is SampleResult and how can I use this?
I know that there are a lot of questions, and some of them (if not every one ;)
) may seem a bit funny, but answers for that questions will help me to
understand usage of Beanshell in JMeter. Please help ;)
