Compare Only Two HTTP Requests

[Nicholas Keene <nk...@wxc.com>]

Hello list. I have been futzing with JMeter for a long long time trying
to figure something out. I have a test which needs to make a request,
extract a datum, make a second request, extract a second datum, then use
those two data when making a final pair of requests, and finally compare
the results of those two requests. So, to be clear, I make an "variable"
request which gives me a list of variables, then for each variable I
make a "datakey" request which tells me the datakey for that variable,
then I use the variable and the datakey to make a pair of requests, and
compare the results of that pair of requests.

 

My problem is in the very final step. I can't figure out how to get
Compare Assertion to compare the results of that last pair of requests.
I've tried moving my test objects all around, using all sorts of
controllers in all sorts of ways, and I haven't found the right way yet.
I hope one of you can point out what I'm doing wrong.

 

My tree looks like this:

 

* Thread Group

** User Defined Variables

** CSV Data Set Config

** HTTP Request (the "variable" request)

*** Regular Expression Extractor (to get the variables)

** ForEach Controller (to loop over the variables)

*** HTTP Request (the "datakey" request")

**** Regular Expression Extractor (to get the datakeys -- but there is
really only one datakey)

*** HTTP Request #1 (first request of the final pair of requests)

*** HTTP Request #2 (second request of the final pair of requests)

*** Compare Assertion

** View Results Tree

** Comparison Assertion Visualizer

 

Now, what I end up getting in the CAVisualizer is that Request #1 and
Request #2, instead of being compared to one another, are each compared
to the datakey request. I can see that the Compare Assertion must work
by comparing the first request in its parent's group, to each other in
that group. That would be fine, but in no way have I been able to put
Request #1 and #2 into a Simple Controller, or into a ForEach
Controller, or anything else to force the Compare Assertion to compare
#1 and #2 to eachother.

 

I've tried every combination I can think of and I'm quite stymied. Help!

 

Nicholas

Re: Compare Only Two HTTP Requests

[Deepak Shetty <sh...@gmail.com>]

Try
*Rest Of Test
*Simple Controller
** HTTP Request #1 (first request of the final pair of requests)
** HTTP Request #2 (second request of the final pair of requests)
** Compare Assertion

Add the compare assertion visualizer to check.
