Reading from Response
Hi,
i want to read something out of a response from a webservice test.
e.g. i'm looking for an ID like "abcd1234" on a response,
after successfully read-out, i want to use this ID as a user defined
variable for the second step.
is this possible?
thanks in advance
knut

Hi Knut,
It sounds very possible. Use a Regular expression post processor to
extract the ID from the response and put it into a variable. Then use
the variable in the second step to help with your request. See the
manual, post processors - Regular Expression extractor for more information.

Is the list known in advance, or is it only known by extraction from a
previous result?
If the list is known in advance, then the easiest would be to write a
script to create a file containing all the combinations.
If you don't care if the criteria contain duplicates (e.g. DOG+CAT+DOG
or DOG+DOG+DOG et.) then just concatenate the 3 random selections - no
need for the random controllers.
Otherwise, you will have to write some code (jexl, javascript or
beanshell) to generate the criteria, in which case use the match-all
Regex feature.
Or it may be easier to write code to remove the duplicates from the
concatenation.
Something like:
- split string on '+'
- save unique values
- join values using '+'
If the order of items is not relevant then you can use a hash to
eliminate duplicates.
Otherwise you could use something like ListOrderedSet from Commons
Collections (JMeter already includes the collections jar).
If you use the Match-All Regex, then instead of splitting the string
you can read the variables in turn into a Hash or a Set as above.

Building random string
Posted by Hiro Protagonist <hi...@googlemail.com>.
Hi all,
I have searched for a solution (or building blocks to a solution) to
this, but haven't found anything so far, and all my attempts to solve
this problem elegantly have failed - perhaps you can help...
I am trying to send a request, which contains within it some search
criteria, that can narrow down a search result when submitted.
Let's say, for argument's sake, there are 3 terms that can be used to
restrict what comes back. Any combination of these 3 terms can be used -
and herein lies the problem. I can, using a regex and random controller,
send a request that randomly picks from one of those 3 terms (by
creating 3 child requests of the random controller), but what I can't do
is pick a random COMBINATION of these values.
Furthermore, following the 'regex-and-random-controller' approach, I end
up having to manually create a request for each of the possible
combinations ( => cartesian product).
In case I haven't been clear, an example:
For a pet shop, you can display what kinds of aninmals you would like to
see, e.g. 'dog','cat','bird'.
I can randomise and send requests using either only dog, or only cat, or
only bird, but I can't figure out how to send requests for a random
combination of any of those three:
<criteria>DOG</criteria>
or
<criteria>DOG+CAT</criteria>
or
<criteria>DOG+CAT+BIRD</criteria>
I hope I have explained this sufficiently... Thanks for your help.
Regards,
hiro
