From a csv file, I need to pass
224,329,429
as a single value to one of the parameter in HTTP request.
I have parameterized using CSV data config. But, only 224 is getting passed.
I want 224,329,429 to be treated as a single value.
Please let me know how do I achieve this. Should I change anything in CSV config or CSV file to make this work?
Just use __StringFromFile() function instead of using CSV Data Set Config.
The __StringFromFile() function reads next line from the file each time it's being called so it seems to be a lot easier to stick to it for particular your scenario.
The syntax is as simple as ${__StringFromFile(/path/to/your/file.csv,,,)} and the function can be used anywhere in the script, i.e. directly in the request parameter section.
See Apache JMeter Functions - An Introduction to get started with the JMeter Functions concept and comprehensive information on the above and other JMeter functions.
You should change your delimiter to a not used character e.g. #
In that way you will be able to get full line for every request
Use ${__FileToString(dummy.csv,,payloadvar)} function. It makes the file independent that mean you can use any file extension example: .txt, .csv, .excel etc..
Just keep the string in dummy.csv and it will fetch the whole string.
benefit of using this function is, it will not consider comma's so in case your string has comma separated values then this is the best option.
Just use %2C in the place of comma.

I have a variable that I use in my API's header.
It contains many special characters in that string so JMeter cannot digest the value.
'myCode' variable I plan to use in CLI (NON-GUI) mode so I need to be able to control it.
Sometimes I see also double or single quotes ('"' and "'")in the string so it can be a case that I need to deal with this
Any ideas on how to handle this?
${__P(myCode,0$M#3C3dKLo&1=9gIYP#CvC5.sWNvDD2mTWmn)=uoj}peA6W8?ry]s/Tn}J{C:Z%,J?M0+{&&ywi]3wM"1lG(&!q++88b1B>I2G1=+cso}trWmOSIo]INi^&%&^GYUFFsgdnJ.TsPTM[Jq+g2CWKvRZ495G0DqH>Yj%sUPqhj2aCmbWun)}
JMeter can "digest" the value, if you're trying to override the property via -J command-line argument - refer to your shell documentation as some characters might need escaping.
Another option is defining your property in user.properties file or in a completely separate file and using __FileToString() function to read it
I am trying to parameterize my request using CSV Data Set Config. My input includes double quotes("), colon(:) and brackets([])
Eg: fiscal_year ":["2021",2019]"
Had tried with it, but in the actual results its passing as "fiscal_year "":[""2021""
Please share your inputs on what am i missing on the input paramter.
I don't think it's due to double quotes("), colon(:) and brackets([]), CSV stands for comma-separated values so JMeter treats it as a delimiter and reads everything including to the first comma.
So you might want to change the "Delimiter" to something else:
It's hard to come up with a comprehensive solution without seeing at least couple of lines from your CSV file and the way you're parameterizing the HTTP Request with JMeter Variables
In case you have one entry per line in the CSV file it might be easier to go for __StringFromFile() function which reads next line from the file each time it's being called. See Apache JMeter Functions - An Introduction for more information.
Using JMeter to support functional API testing and have run across a problem with reading data from a CSV file. The data from the file is used in building a POST data body which contains something like this:
"wibbles" : ${wibble-var},
${wibble-var} is read from a CSV file and has the format :
["wibble1","wibble2","wibble3"]
... there are over 1000 wibble values in the list.
If "wibbles" : ["wibble1","wibble2","wibble3"]... is hard-coded into the POST body, then JMeter is happy, builds the POST request and does the business, but it's proved impossible to create a CSV file with even the 3 value example above, that JMeter will parse. JMeter skips the thread containing the 'CSV read' without building the POST request or sending it, so there's no response to examine, and a Debug Sampler is similarly skipped. I've heard rumours that doubling up the quotes can work but haven't been able to find the right syntax. Can anyone throw any light on this issue? Thanks
Double quotes will work if you can get "wibble1,wibble2,wibble3" & if you set Allow quoted data to true in CSV data set config
You can get this value and then use beanshell preprocessor to convert to the format "wibble1","wibble2","wibble3".
If you want to get in this format "wibble1","wibble2","wibble3" directly, you can use \t as the delimiter & modify the data in the CSV file accordingly.
Trial and error led to the following solution.
The format of the single data variable I needed to parse is ["value1","value2","value3"] (i.e a JSON array.) and this is exactly what the CSV file contained (with a header name of course on the first row), including the [ and ] brackets.
I modified the parameterised POST body to:
"wibbles": [${wibble-var}],
-- that is, I moved the square brackets out of the CSV file so that the CSV file now just contained the quoted elements of the array:
"value1","value2","value3" etc
I then set the delimiter in the CSV Data Set Config to |
And Allow Quoted Data to FALSE. <--- This was a bit counter intuitive but without it JMeter would not read the whole comma separated list of 2000 quoted strings as a single variable.
With these changes in place the script executed correctly.
Thanks again for the responses, I will definitely look at the __String functions mentioned.
I would go for the following options:
If your "wibbles" are a single string which you need to pass a a JSON Array it might be a lot easier to access them via __StringFromFile() or __FileToString() functions like:
"wibbles" : ${_StringFromFile(/path/to/file/containing/wibbles,,,)},
If you need to access individual "wibbles" and your CSV file is basically a JSON file:
Add HTTP Request Sampler to your test plan (before one which sends these "wibbles") and configure it as follows:
Protocol: file
Path: c:/testdata/yourfile.csv
Add JSON Path PostProcessor and use a JSON Path query to store the "wibbles" into a JMeter Variable(s)
Will jmeter function FileToString(path) takes dynamic values.
I need to use around 400 json files as a input. so planning to use FileToString($fileName}) in body data. By providing the filename column in csv. But it seems Jmeter is checking filename as file instead of getting value from csv.
You need to wrap your ${fileName} into __eval() function. As per documentation:
The eval function returns the result of evaluating a string expression.
This allows one to interpolate variable and function references in a string which is stored in a variable.
So you need to change your expression to look like:
${__FileToString(${__eval(${fileName})},,)}

my soap/xml response looks like below:
<Account><Accountnumber>1234<Description>savings</Account><Account><Accountnumber>1235<Description>Savings1</Account>
I would like to store accountnumbers in a variable or array and would call it in another soap xml request in jmeter for knowing their details. can somebody help me how i can store and how i can call that variable ? I am new to Jmeter.
Thanks in advance.
If the account numbers are static, you're better off using a .csv file, as mentioned by Vance because the CSV data reader has less overhead then regex.
However, if you want dynamic data, it's very easy to do.
Download "regex coach" to help you write regular expressions. It's an amazing tool.
Attach a "regular expression extractor" as a child to your SOAP/XML request
Run the request once, to get the reponse
Copy the response into regex coach (or whatever tool you use), and write your regex. It'll look something like this: (\d+?)\D (look for any digit after the text accountNumber and stop after a non-digit)
Configure the rest of the regex. In this case, you'll want:
Apply to: Main Sample Only
Response filed to check: Main Body
Reference Name: VariableName
Regular Expression: See step 3
Match No: 1 (1st match) 0 (any match) or -1 (all
matches, useful when doing "FOR EACH
found" logic
Default Value: failed
TO use your variable account number in other requests, simply use the reference name. In this example: ${VariableName}
Reference: http://jmeter.apache.org/usermanual/component_reference.html#Regular_Expression_Extractor
You may save your data in a ".csv" file and Jmeter can read it easily through its csv data set config.
Use ${your data variable} in your scripts.
