I've the following URL
https://x.x.x.x/x/continue?processId=1234567&formAction=register
I need to extract the proccessId to use in the following request, but in JMeter with XPATH extractor value
//*[#id="signupForm"]
I can't recover the value, is there any option to solve it?
Easier to use Regular Expression Extractor for fetching value from URL
Add as a Post Processor of request Regular Expression Extractor with values:
Regular Expression: `processId=(\d+)&formAction=register`
Template `$1$` (indicate first group)
Match No. `1` ( fetch the first number)
Reference Name: `yourVariableName`
and then use ${yourVariableName} in your next request(s).
Note: If you are extracting from Request's URL you need to choose URL in Field to Check radio buttons.

I want to save two value as key value pair in List from previous sampler of Jmeter so that I can use that string in pre Preprocessor
Try the below steps:
Add the 'Regular Expression Extractor" from the Post-Processor
Define the required variables
Say, for a single variable set the fields in Regular Expression Extractor as below
Field to check => Body
Name of the created variable => username
Regular Expression => username=(.+?)
Template => $1$
Match No => 1
Now, Pass the variable in the HTTP request > Parameters
Say,
Name = Username
Value = {$username}
Run the test

It depends on the format of the data you're getting in the response and the format of the data you need to pass in the next request.
In order to get a comprehensive response you should provide at least partial response data and desired at least partial request body
Normally you should use a Post-Processor for extract data from the response:
For HTML - CSS Selector Extractor
For JSON - JSON Extractor or JSON JMESPath Extractor
For XML - XPath Extractor or XPath2 Extractor
For everything else - Regular Expression Extractor or Boundary Extractor
all of them extract values into JMeter Variables which can be used in the next requests
I recorded the .JMX script in Jmeter and one of the request is as below
POST http://www.hello.com/auth/nqa/md/login
Body data:
{"domainId":"nqa","code":"12345skdkdk"}
I would like to send the "code" field dynamically and for that I added the regular expressing extractor as below enter image description here
When i re run the script , the code value is not replaced with the dynamic value.
Not sure what part i am missing in the regular expression extractor or in the Body data field
First of all, you cannot extract the value from the request body using the Regular Expression Extractor, normally you should extract the dynamic values from the previous response so inspect the whole flow using View Results Tree listener and look for your "code" value there
Your regular expression extractor in its current configuration will return random value in the parentheses so it could be domainId, nqa, code or 12345skdkdk. Going forward if you need to get some dynamic data from JSON go for JSON Extractor or JSON JMESPath Extractor
List item
you should do three-step of below
go to the random variable according below picture
Define random variable name . in this case we set variable name to code1 and set min & max value to this
Use ${code1} variable to your data section
I have JSON responce
{
"sessionName":"eL7tYgxhYh",
"imageSrc":"/Common/CaptchaImage/**eL7tYgxhYh**?t=636573960197174426"
}
How I can get a random value string "eL7tYgxhYh" in href by JSON Path Extractor with JMeter?
You cannot achieve this using JSON Extractor as it can only deal with JSON Objects, i.e. you can easily get full value of the imageSrc attribute, but not more.
I would recommend switching to Boundary Extractor instead, the relevant configuration would be something like:
Name of created variable: anything meaningful, i.e. href
Left Boundary: CaptchaImage/
Right Boundary: ?
That's it, the "interesting" value should be now extracted and you should be able to refer it as ${href} where required
Demo:
More information: The Boundary Extractor vs. the Regular Expression Extractor in JMeter
JSON format is in key-value pair so you just need to mention the key for which you need to extract the value. As in your case, you can use following JSON path expression for fetching the text mentioned by you:
$.sessionName
You can also use regular expression extractor which is another most important element of JMeter to extract the dynamic variables. Please refer to below blog of RedLine13 for more information on Regular Expressions:
https://www.redline13.com/blog/2016/01/jmeter-extract-and-re-use-as-variable/
Let me know if you have any further question
Above figure shows how to access access_token response of json and store it in access_token variable. In your case need to replace below.
JSONPath Expression use
$..sessionName
Destination variable Name
SessionName

To get required string from result string you can use BeanShell Assertion to split the string.

In need to pass a data from a response to the subsequent request. Something goes wrong and the default variable value appears in the request.
First request returns the JSON in response body which looks like this:
{"issued_at":"2016-01-14T12:41:01.000Z","expires":"2016-01-14T12:46:01.000Z","id":"j6M ... MTA=="}
I extract the value of the id attribute using the Regular Expression Extractor:
Then I pass the token variable to the subsequent request parameter:
But the request is created with the default value of the variable:
There is a JSON Path Extractor designed to deal with JSON content type, I believe it would be easier to use it.
The relevant JSON Path query will be as simple as $..id
See Using the XPath Extractor in JMeter (scroll down to "Parsing JSON") for comprehensive information on plugin installation and usage and JSONPath - XPath for JSON for JSONPath language reference and examples.
In regards to your Regular Expression Extractor configuration:
remove 1 from Match No.
Provide $1$ as Template
If you look at the Regular Expression Extractor documentation, the field Template is required. I suggest you to use value $1$ and try again.
The problem was resolved by setting the "Field to check" radio button to "Body" at the "Regular Expression Extractor" dialog and by setting the Template field value to $1$.
Thanks to alphamikevictor and Dmitri T for help!
You should use ${token_g1} to get the value of the first group of the regex match (the value you're looking for).
In my application while executing the first request one unique key is generated which key is required for Next all the request. let me how to automate such scenario in Jmeter.
The process should look as follows:
Add Post Processor to the first request
Configure it to extract the required value and store it into a JMeter Variable
Use JMeter Variable from step 2 in your next request.
Depending on response data type you have the following choices:
Regular Expression Extractor - for text
CSS/JQuery Extractor - for HTML
XPath Extractor - for XML and XHTML
JSON Path Extractor - for JSON
It is also possible to extract data from files i.e. if response is in PDF format, but it's a little bit tricky
Example configuration to store the whole response:
Reference Name: any suitable variable name, i.e. response
Regular Expression: (?s)(^.*)
Template: $1$
You can refer the extracted value as ${response} where required. You can also amend the regular expression to extract response part instead of the whole response. JMeter uses Perl5-compatible regular expressions, see Regular Expressions User Manual Chapter for details
You can use regular expression extractor to extract the key from the response of your first request and use the extracted key for subsequent requests. To achieve this:
Right click on the first request and add post processor: Regular Expression Extractor.
Create your regular expression and provide values in other required fields. Please refer to JMeter component reference http://jmeter.apache.org/usermanual/component_reference.html#Regular_Expression_Extractor
Extracted value will be saved in the variable given as reference name
Use this variable in subsequent requests
Here is an example test plan with results.
