I m sending a httprequest nd using formdata as Content type.I added Values in Jmeter Parameter tab and read those parametrs in Preprocessor using sampler.getArguments().getArgumentsAsMap().But one empty key value pair is addded at the last in that map.
Code :
jsonPayload = JsonOutput.toJson(sampler.getArguments().getArgumentsAsMap())
log.info("Arguments as Map"+jsonPayload)
Result :
2022-12-23 12:40:49,347 INFO o.a.j.m.J.Encrypt Payload: Arguments as Map{"Name":"test1","ID1":"test2","tID2":"test3","ID3":"test4","":""}
I cannot reproduce your issue using JMeter 5.5 and a single simple HTTP Request sampler:
So it might be the case there is another HTTP Request sampler with another empty argument somewhere in the JSR223 PreProcessor's scope or you're adding an empty argument somewhere else and it appears in the second iteration.

I do a POST request using Jmeter and I parse the JSON response using the JSON extractor. When i use the debug sampler I could see the Variable is assigned with the value properly but that value goes as null in the subsequent request
Below is the request URL for the next sample /XXX/XXX/XXX/XX/${recordingjobid}
but this value recordingjobid is not substituted with the value.
I can only think of not proper placement of the JSON Extractor.
For example if you have it at the same level as several samplers - it will be run after every of them (including the Debug Sampler) and each next one will be overwriting the value set by the previous one as JMeter Variables are local to the thread and don't allow duplicates.
So my expectation is that if you move the JSON Extractor to be a child of the request which returns the JSON - it should resolve your issue.

In my case i have created one HTTP Request with all the possible parameter as below -
My .csv file is looking as below -
For some test case i need to send details in one or two parameter only, not for all. Now how can i do that in the same HTTP request without creating a new one?
Theoretically you can just send empty parameter values, just make sure that you have a blank value in the CSV file, i.e.:
param1,param2
foo,bar
baz,
,qux
Alternatively if you want to completely remove the parameters with empty values from the request you can add a JSR223 PreProcessor as a child of the HTTP Request sampler and put the following code into "Script" area:
def newData = new org.apache.jmeter.config.Arguments()
0.upto(sampler.getArguments().size() - 1, { idx ->
def arg = sampler.getArguments().getArgument(idx)
if (!arg.getValue().equals('')) {
newData.addArgument(arg)
}
})
sampler.setArguments(newData)
This way JMeter will remove the parameters which don't have their respective values from the request:
In the above example sampler stands for HTTPSamplerProxy, see the JavaDoc for all available functions decriptions

Run Get method to get the data of the policy - response is encrypted.
Run a Post method to decrypt the response from step 1
On the response from Step 2 there is the field policyStatus and will be changed to value = 2
Encrypt the decrypted payload with changes in the policyStatus. I created a regular expression extractor in step 2 to get the response, but the problem is if I directly parameterized it in this step I wont be able to change the value of policyStatus, is there a way to change the value after extracting without posting it so that I can encrypt it and then post it.
I tried the __strReplace() function but this will be possible if the request is step 4 is not parameterized. see below
Actual Body(Parameterized):
{
"isEncrypt": true,
"payload": "{${payload}}"
}
Body(Not Parameterized):
{
"isEncrypt": true,
"payload": "{\"policyNumber\":\"\",\"policyStatus\":\"1\",\"ownerName\":\"\",\"exchangeRate\":1,\"product\":{\"productName\":\"",\"category\":\"T\",\"shariaIndicator\":\"",\"currency\":\""},\"billings\":[{\"type\":\"",\"amount\":0,\"currency\":\""},{\"type\":\"",\"paidToDate\":\"2019-07-08\",\"mode\":\"",\"amount\":,\"currency\":\"",\"minimumPayment\":,\"outstandingPeriod\":0,\"paymentSuspend\":}]}"
}
the policyStatus is inside the payload field which comes from the response on step 2.
tried the advice from this --> How to store entire response and update it for next rest call using Jmeter
but this applies in the value of the single field.
Add JSR223 PostProcessor after the Regular Expression Extractor in step 2
Put the following code into "Script" area:
vars.put('changedPolicy', vars.get('myVar').replace("\\\"policyStatus\\\":\\\"1\\\"","\\\"policyStatus\\\":\\\"2\\\""))
Replace myVar with your actual JMeter Variable reference name from the Regular Expression Extractor
That's it, the JSR223 PostProcessor will generate changedPolicy variable with the policyStatus value set to 2
Demo:
vars keyword used in the Groovy script is the shorthand for JMeterVariables class instance, it is used for reading myVar variable value and writing the replacement into changedPolicy variable. See Top 8 JMeter Java Classes You Should Be Using with Groovy to learn more about JMeter API shorthands available for Groovy scripts.
I have data in csv and somewhere cell value is blank and when I am using this blank value in my HTTP request body data then it is replacing like "", but I want to replace as null without quotes. Please help here.

You can do it dynamically using i.e. JSR223 PreProcessor and the following Groovy code:
def body = sampler.getArguments().getArgument(0).getValue().replaceAll('\"\"','null')
sampler.getArguments().removeAllArguments()
sampler.addNonEncodedArgument('', body,'')
sampler.setPostBodyRaw(true)
Add JSR223 PreProcessor as a child of the HTTP Request and it will replace blank values with nulls.
Where sampler stands for HTTPSamplerProxy class instance, it provides access to request body, url, headers, cookies, etc.
The other simple solution to resolve this problem is to use "" in the test data itself.
Check the below screenshots :-
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.
