I have a jmeter test that I have created that does a post and then runs a secondary post with a string from the first response. I have a regular expression extractor that is getting the information from the response correctly, but when I try to call it in the next post it returns a value of 0. My question is: How do I store this value and reference it correctly in the second post?
Regular Expression Extractor:
Response text:
response_code=2 response_code_text=Missing required request field:
Order ID. time_stamp=1479849486545 retry_recommended=false
secondary_response_code=0 order_id=356005935614233
capture_reference_id=1 iso_code= bank_approval_code=
bank_transaction_id= batch_id= avs_code=
credit_card_verification_response= reference_id=1 bin=
retrieval_reference_number= payer_identifier= system_trace_number=
captured_amount=0.00 emv_data= bank_response_code=
RegExp Tester:
Variable reference call in second post:
I found the answer to my issue, I simply needed to change the Match No to "1". Then I was able to pass the order_id into the next post.

In my first request I am able to extract the value using Regular Expression Extractor which is clearly visible into the debug sampler. The value is extracted by setting the following options in Regular Expression Extractor:-
Name of Created Variable:- instanceUID
Regular Expression:- "InstanceUid":"(.*?)"
Template:-$1$
Match No:-1
Default Value:- (Blank)
The value that I want to pass in the next POST request is visible as:-
instanceUID_g1=2ab5dfb8-a217-4ff2-9025-523565b7b7ad
And the body for the next HTTP POST request is set like this:-
${"iInfo":{"InstanceUid":"${instanceUID_g1}","Registry":"${Registry}"}}
When this request seen in detail inside View Results Tree looks like:-
${"iInfo":{"InstanceUid":"${instanceUID_g1}","Registry":"AAX"}}
As seen the value of ${instanceUID_g1} did not get substituted in the POST body as was for variable ${Registry} which was taken from CSV config.
Being new to Jmeter can anyone suggest what did I miss?
Most probably your Regular Expression Extractor placement is not very correct, be informed about JMeter Scoping Rules concept
If you place Regular Expression Extractor as a child of the request - it will be applied to this request only
If you place Regular Expression Extractor at the same level as several requests - it will be applied to all of them
in the latter case it will be applied 1st to 1st sampler, then to Debug Sampler, then to 3rd sampler so on 2nd step it will be overwritten, most probably that's your problem
Also it appears that you're getting the data from JSON so it makes more sense to use JSON Extractor or JMESPath Extractor
Im running a test plan containing 10 requests i need to get the variable value from 3rd response json to be passed to request URL of 10 th request passed . any way we can use json extractor to do this?
This can be accomplished by using any of the post processors for correlation in amongst any of the requests. I have shown an example below with JSON Extractor
Request Sample
The value that I am going to extract from 3rd request's response is "I am the value to be fetched from 3rd response"
JSON Extractor
I am using the below syntax in JSON Path Expression to extract data from "valueToBeFetched" json object and storing it in variable named "extractedValue_C"
$..valueToBeFetched
10th Request
Replacing the extracted value with syntax ${extractedValue_C} in 10th request
Output
Response Captured from 3rd Response
Captured value passed in 10th request
Hope this helps!
JSON Extractor obeys JMeter Scoping Rules so if you put it as a child of the 3rd request - it will be applied to 3rd request only.
If you come up with a valid JSONPath matching the value you want to extract - the value will be saved into a JMeter Variable which can be used anywhere after 3rd request (where it is defined or overwritten in next iteration)
I need to take the input for next page from previous page source.
Previous page source:
In next page I need to pass this departure city as input in URL.
Sample URL:
/findflight?depart=Acapulco
Here I want to pass the Departure city's(previous page) in next page URL.
So, how can I parameterized this in jmeter??
Let me know if anyone need any additional info on this!!
You can use "Post Processor" like "Regular Expression Extractor" or Boundary Extractor and then pass it in the next sampler path as ${varSam}
Below is a sample where I am using Regular Expression extractor to fetch a value and putting it in a variable. So, this is your request from where you have to fetch the departure city.
Here I am passing that variable in the URL
Hope it helps
Add CSS/JQuery Extractor as a child of the request which returns the above HTML
Configure it as follows:
You will get a random city stored as depart variable and will be able to access its value as ${depart} where required
Optionally you can extract all the values by setting "Match No." to -1, this will give you the following variables:
See How to Use the CSS/JQuery Extractor in JMeter for more information if needed
It is resolved by using the Post Processor(Regular expression extractor). Applied this to the page response.
Page response
parameterized this as following:
Request for the next page by using the above parameterized value
Thanks for the help!!
I was hoping someone may be able to help with the following issue I have.
I have a 'HTTP Request' sampler that makes a POST request. The response data for this request as per the results tree is:
<script>window.document.location.href='handler.ashx?act=wzfin\x26req=nav\x26mop=requirements!new_finish_wiz\x26pk=0c86ea74-c067-4bcf-a49d-be7d0e420fbf';</script>
I want to grab the value for the pk parameter in the response URL above and store in a variable called REQUIREMENT_ID. I have set up a 'Regular Expression Extractor' for the sampler and set it up as per below:
Apply to: Main Sample Only
Field to Check: Response message
Reference Name: REQUIREMENT_ID
Regular Expression: (?<=pk=)(.*)(?=\')
Template: $1$
Match No: 1
Default Value: NOT_FOUND
However, when I run this, NOT_FOUND is being returned. Any ideas what I might be doing wrong?
`Regular Expression Extractor screenshot
Change your regular expression to this <script>.+pk=(.*?)'
And change your field to check to Body
Try this: ".pk=(.?)'"
Not to sure why you way doesn't work to be honest.
I want to manipulate the request body of HTTP thread based on the data extracted (using 'Regular Expression Extractor') from the previous HTTP response.
Here is the scenario:-
I have extracted the statusFlag and statusId from 'HTTP request 1' as:
Ref name: status
Reg. Exp: "statusFlag":"(\w+)","statusId":"(\w+)"
So, first I want to check that the value of statusFlag is 'New' or not.
If it is New then I have to proceed and feed statusId in next HTTP request or else display statusFlag mismatch.
Need help. Got stuck badly.
I believe Response Assertion is what you're looking for. Add it after the Regular Expression Extractor and configure it as follows:
Apply to: JMeter Variable -> statusFlag (or your reference name)
Pattern Matching Rules: Equals
Add New as a "Pattern to Test"
The assertion will check whether "statusFlag" is "New" and if not - it will fail the sampler and report the expected and the actual value.
Optionally you can add If Controller after the Response Assertion, use ${JMeterThread.last_sample_ok} as a condition and place 2nd request as a child of the If Controller - it will be executed only if "statusFlag" is new.
See How to Use JMeter Assertions in Three Easy Steps guide for more information on conditionally setting pass or fail criteria to requests in your JMeter test.
That's how your Jmeter project should look like.
Regular Expression Extractor stores extracted value in ct variable that can be accessed in If Controller as "${ct}" == "yourvalue" and, if true, can be also sent as a part of Request 2 body using the same ${ct} reference.
