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.

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.
Why I cannot click on Parameters tab in HTTP Request section after I insert JSON body data in Body Data tab? I tried to define correlation and of course this will require us to define the variable as well. Just wondering, after I'm done with correlation part, how can I insert the variable in Parameters if it is disabled?
You can't send Parameters and Body Data, you must choose only one option of sending request body
If you need to send extra parameters in additional to request body then use query parameters in Path field, for example
path?parameter1=value¶meter2=value2
If you want to variablize/correlate the JSON request body - you can put the relevant JMeter Functions/Variables directly into "Body Data" tab
as you can see all the functions/variables are getting replaced by their respective values.
Also most probably you're getting JSON as the response so it makes sense to consider switching to JSON Extractor or even better JSON JMESPath Extractor for the correlation.
With Jmeter I am trying to save the request body using the Flexible file writer in csv file format. The request body is a json format something like this :
POST https://testurl
POST data :
{
"label" : test
}
The request body is getting saved to the file but not in a single cell. It is coming in multiple rows. How can I save the complete request body to one single cell.
There is no such a thing as "cell" in CSV files so your question doesn't make a lot of sense
If your request body is multiline you might want to remove these line breaks before saving the request body, it can be done using i.e. JSR223 PostProcessor and the following Groovy code:
def requestBody = prev.getSamplerData().replaceAll('[\n\r]', '')
vars.put('requestBody', requestBody)
You will need to declare this requestBody as a Sample Variable in the user.properties file:
sample_variables=requestBody
and once done you will be able to access the value in the Flexible File Writer as variable#0

Thanks for the response. When I try this I am seeing the requestdata like shown in the screenshot. And incase if there are multiple controllers the request body for all of them will be appended one after another in the same line.

I'm trying to solve a test data issue in Jmeter. Can anyone of you have a look at below problem statement and advise here please ?
Requirement: Need to send all entries in a CSV file to HTTP request body in 'one' request to the end point.
Example CSV File:
"adsfas123wsf00000wqefqwe52145t10000",
"fdfrgvergq120947r0000dwsfqwaef237sadf",
"wfrqwef7865034r78tkahsefjh6985r7asfdaf",
"qefqwe52145t10000adsfas123wsf00000w",
"wsfqwaef237sadffdfrgvergq120947r0000d"
HTTP Request Body:
["${data}"}]
When the data is substituted, I should be able to get below output.
[
"adsfas123wsf00000wqefqwe52145t10000",
"fdfrgvergq120947r0000dwsfqwaef237sadf",
"wfrqwef7865034r78tkahsefjh6985r7asfdaf",
"qefqwe52145t10000adsfas123wsf00000w",
"wsfqwaef237sadffdfrgvergq120947r0000d"
]
Problem Statement: When I use CSV data set config. file, I'm unable to concatenate all entries into one single request body. My understanding is, CSV data set config. the file is not the right option here.
Did some search in StackOverflow and followed a method to achieve above using JSR223 PreProcessor' and the link is, How to send multiple json body using jmeter?.
Followed the above link and tried added below custom code provided.
def builder = new StringBuilder()
new File('/path/to/plans.csv').readLines().each { line ->
builder.append(new File(line).text).append(System.getProperty('line.separator'))
}
sampler.getArguments().removeAllArguments()
sampler.addNonEncodedArgument('', builder.toString(), '')
sampler.setPostBodyRaw(true)
Upon running, I get below error message,
Caused by: java.io.FileNotFoundException,
"adsfas123wsf00000wqefqwe52145t10000",
"fdfrgvergq120947r0000dwsfqwaef237sadf",
"wfrqwef7865034r78tkahsefjh6985r7asfdaf",
"qefqwe52145t10000adsfas123wsf00000w",
"wsfqwaef237sadffdfrgvergq120947r0000d" (The filename, directory name, or volume label syntax is incorrect)
If the file is not found, then how come the entries are read and displayed in the log viewer?
Also, how do I link the output of custom code to the request body? Or is it taken care of by the custom code itself?
You have an error in your code, change this line:
builder.append(new File(line).text).append(System.getProperty('line.separator'))
to this one:
builder.append(line).append(System.getProperty('line.separator'))
If you want to send the full contents of the file you don't even need to go for scripting, you can use __FileToString() function right in the "Body data" tab of the HTTP Request sampler:
${__FileToString(/path/to/plans.csv,,)}
And last but not the least if you need to generate JSON from the plain text it might be a better idea to go for JsonBuilder class, see Apache Groovy - Why and How You Should Use It and Apache Groovy - Parsing and producing JSON
Two steps:
Add a User Parameter Pre-processor before the HTTP request:
Name: DATA
User_1: ${__FileToString(/path/to/plans.csv,,)}
Add the following to request body:
${DATA}
I am facing some trouble using jmeter. This is my use case, I am using CSV data source parameters to construct a HTTP POST request, the request body is read from a CSV column
which contains some placeholders like ${source_id}
I want to replace these placeholders with jmeter parameters which I am initialising through a regex/json extractor(read from the response of last PUT request). I tried using the jmeter variable name in the CSV file but the variable values are not getting substituted. I guess I will have to use the beanshell pre-processor to modify the HTTP POST request body. Can anyone help with the methods I can use to get the HTTP POST request body.
Something like
String requestBody = sampler.getArguments().getArgument(0).getValue();
should help.
sampler is a shorthand to parent sampler class instance, in your case it will be HTTPSamplerProxy, see the JavaDoc for all available methods and fields.
I would recommend considering migration to JSR223 PreProcessor and Groovy language as it is much faster and less resources consuming than Beanshell. Valid Beanshell code will be valid Groovy code so you should be able to convert to JSR223 elements with no or minimal changes. See Groovy is the New Black article for more details.
