How to save response in a variable in jmeter - post

I am performing load testing on my server using jmeter.
In one of my post requests, I receive a unique id in the response.
I need to send this id as a parameter in the following post requests.
I am new to jmeter and don't have any idea how to do this.
Help would be really appreciated.

If you need to store the whole response into a variable - take the following steps:
Add Beanshell PostProcessor as a child of the request which returns response you're looking for
Put the following line into the PostProcessor's "Script" area:
vars.put("response", new String(data));
Refer extracted value as ${response} where required
See How to Use BeanShell: JMeter's Favorite Built-in Component guide to lean more about Beanshell scripting in JMeter
Alternatively you can do the same with the Regular Expression Extractor, in that case relevant configuration will be:
Reference Name: response
Regular Expression: (?s)(^.*)
Template: $1$
If you need a part of response, not the whole response you can amend Regular Expression according to your needs as per Regular Expressions chapter of JMeter's User Manual

If you really need to store the whole response into a variable, do the following:
Add JSR223 PostProcessor as a child of the request which returns response you're looking for
Put the following line into the "Script" area:
vars.put("response", prev.getResponseDataAsString());
Use then this response as ${response} where you need it
But you rarely need to use the whole response and you should avoid it for big , in this case it is much better to use the Extractor that suits your response format:
JSON Extractor for JSON
CSS/JQuery Extractor for HTML extraction
XPath Extractor for XML
Regular Expression Extractor for all of them or any textual format

You can use JMeter's Post-Processor Regular Expression Extractor to extract the required value from response. Just Add this under the sampler whose response will contain the required value.
In Reg expression extractor, you will define the variable name (referenceName), RegularExpression, template etc. Later you can use the value in this variable. To learn how to use Reg expression extractor you can refer to following tutorial.

I know this question is old but I agree with #UBIK you should probably use a JSON extractor. I am working with a load test that is sending over 100 requests per second and I need to reuse the value in a specific JSON key, so I'm using a JSON extractor and saving the values in a .csv file to be used by the next request.
extract the JSON
This is the Groovy script to write it to a .csv file
def myRandomIds = new File("randomIds.csv")
myRandomIds << vars.get("id") + ","
myRandomIds << System.getProperty("line.separator")
log.info(vars.get("id") + " saved to randomIds.csv...")
This is the CSV data config I have set up in my other request that is reading from the csv file. (In my case these .jmx files are automated and parametized using jenkins)

Convert JSON to XML format through Azure Logic app

Scenario 1 - I have some XML files stored in FTP.Those files are being fetched by FTP connector in Azure logic app. Then I am reading those files by parsing it into JSON & storing those objects in String variables for my operation. Then after my processing I want to convert that json back to XML for the output.
Scenario 2 - I am merging multiple XMl files(all are of same structure) into an single one. after merging I can get the output in JSON format but then I want to convert the same into XML format.
So please suggest how can I convert JSON to XML through Logic App & Azure function only.
Try the 'xml' function.

Make sure that your JSON input is structured suitably for conversion to XML, for example you should only have a single element at the top level, which will form your XML root element.

JMeter for each controller - beanshell sampler display multiple variables

I have JSON Request where multiple products nodes returns from there I am using product SKU inside the for each controller as input and sku_value as output which I am using in subsequent request.
Inside this for each controller I have another beanshell sampler where I would like print/display to use other values returns by first JSON request i tried this
Jmeter counter function value to be displayed in Benashell Post Processor or sampler
vars.get("productId_" + vars.get("counter")) but it return NULL
if I use ${__V(productId_${__counter(TRUE,)})} at the sampler name it correctly prints the value but i want this value to printed using log.info
please help.
Double check that ${counter} variable exists and has valid numeric value using Debug Sampler and View Results Tree listener combination
If your ${__V(productId_${__counter(TRUE,)})} works fine you can just use it in Beanshell Sampler's "Parameters" section and refer the value as Parameters in the script:
Also be aware that starting from JMeter 3.1 it's recommended to use JSR223 Test Elements and Groovy language for scripting so consider migrating to Groovy on next available opportunity.

Having a POJO like feature in KarateAPI?

I have been using Karate and RestAssured for sometime. There are advantages and downside of both tools of course. Right now I have a RestAssured project where I have Request and Response object and POJOs. My requests wraps my endpoint and send my POJOs to those endpoint. I do all my Headers, etc configuration in an abstract layer. In case I need to override them, I override them during the test. If not, Its a two lines of code for me to trigger an endpoint.
My way of working with happy path and negative path of an edpoint is that I initialize the POJO before every test with new values in the constructor. Then I override the value that I want in test scope. For example, if I want to test a negative case for password field, I set this field to empty string during the test. But other fields are already set to some random stuff before the test.
But I dont know how to achieve this with Karate.
Karate allows me to create a JSON representation of my request body and define my parameters as seen below example.
{
"firstName": "<name>",
"lastName": "<lastName>",
"email": "<email>",
"role": <role>
}
Then in every test I have to fill all the fields with some data.
|token |value|
|name |'canberk'|
|lastName |''|
|email |'canberk#blbabla.com'|
|role |'1'|
and
|token |value|
|name |''|
|lastName |'akduygu'|
|email |'canberk#blbabla.com'|
|role |'1'|
It goes on like this.
It's ok with a 4 fields JSON body but when the body starts to have more than 20 fields, it become a pain to initialise every field for every test.
Does Karate have a way of achieving this problem with a predefined steps of I need to come up with a solution?
There are advantages and downside of both tools of course.
I'm definitely biased, but IMHO the only disadvantage of Karate compared to REST-assured is that you don't get compile time safety :) I hope that you have seen this comparison.
Karate has multiple ways to do what you want. Here's what I would do.
create a JSON file that has all your "happy path" values set
use the read() syntax to load the file (which means this is re-usable across multiple tests)
use the set keyword to update only the field for your scenario or negative test
You can get even more fancier if you use embedded expressions.
create a JSON file that has all your "happy path" values set and the values you want to vary look like foo: '##(foo)'
before using read() you init some variables for e.g. * def foo = 'bar' and if you use null that JSON key will even be removed from the JSON
read() the JSON. it is ready for use !
You can refer to this file that demonstrates some of these concepts for XML, and you may get more ideas: xml.feature

Jmeter: Dynamic URL encrypted

I'm working on a test plan with Jmeter.
The issue is that I can't retrieve the URL link as he is managed dynamically.
The URL has the following format:
localhost\blablabla?PATHPARAM=qzflh%2FGJHBGDCV%GROPJHVFFFDDFGGCFD%JJYTGVFRTVFGGFF%JUYGBG
I already try to search the value of PATHPARAM in the previous requests to retrieve it using regular expression extractor but I didn't find it.
It seems that this url is generated inside a javascript code but the way to extract it is unknown for me, inside the js code I find the value : var url = actionName + "?" + params ;
Is that any way to catch the content or the var url in Jmeter, else have you any other solution to solve this issue with this dynamic URL.
Many thanks in advance for your help.
I can see 2 possible options:
If you are being redirected to this URL automatically (you might need to play with Redirect Automatically and Follow Redirects boxes in the HTTP Request sampler
If this is the case - you should be able to get it using the following Regular Expression Extractor configuration
If you need to replicate the logic of this param variable calculation - you can attempt to do it using JSR223 PreProcessor which can execute arbitrary JavaScript code

XML Schema - Allow Invalid Dates

Hi I am using biztalk's FlatFile parser (using XML schema) to part a CSV file. The CSV File sometimes contains invalid date - 1/1/1900. Currently the schema validation for the flat file fails because of invalid date. Is there any setting that I can use to allow the date to be used?
I dont want to read the date as string. I might be forced to if there is no other way.
You could change it to a valid XML date time (e.g., 1900-01-00:00:00Z) using a custom pipeline component (see examples here). Or you can just treat it as a string in your schema and deal with converting it later in a map, in an orchestration, or in a downstream system.
Here is a a C# snippet that you could put into a scripting functoid inside a BizTalk map to convert the string to an xs:dateTime, though you'll need to do some more work if you want to handle the potential for bad input data:
public string ConvertStringDateToDateTime(string param1)
{
return DateTime.Parse(inputDate).ToString("s",System.Globalization.DateTimeFormatInfo.InvariantInfo);
}
Also see this blog post if you're looking to do that in multiple places in a single map.
