How to pick json playload from external file in jmeter?
I Want to login with multiple users for that I need to add Json request. I need to pick json parameter/Json request from external file. Please let me know the process so that i can pick json parameter from external file.
Json request for example
{"username":"honey#est.com","password":"Phone#123","provider":"","access_token":""}
If you want to read a single line from a file - go for CSV Data Set Config or __StringFromFile() function
If you want to read entire file - go for __FileToString() function
If you have a folder with multiple JSON files and would like to iterate all of them - check out Directory Listing Config
It's also possible to read a file using JMeter's HTTP Request sampler
this way you will be able to use Post-Processors to extract partial data if needed.

I have one GET request which returns a token. I need to run this request 50 times and each returned token is appended to a single file or array which I can randomly choose and use tokens for other requests. Is it possible in Jmeter
Add a Post-Processor to extract the token and save it into a JMeter Variable
Declare the variable as a Sample Variable
Save the extracted value into a CSV file using Flexible File Writer
Use Random CSV Data Set Config to read the random token from the CSV file created in the previous step
I want to pass multiple CSV/JSON files, those contents should be set as POST body data.
How can I achieve this?
If you have those files present in some folder the easiest is to:
Install Directory Listing Config in order to read file names into a JMeter Variable
Use __FileToString() function in order to read the file contents to the request body
Demo:
please suggest me how to maintain json POST data(for API testing) for multiple test cases in robotframework based on your past experience. Whether to maintain it in excel and separate json files?
If you have a "template" JSON and need to parameterize individual values you can use CSV Data Set Config for supplying these values, you request would be something like:
{
"parameter1": "${value1}",
"parameter2": "${value2}"
}
where these ${value1} and ${value2} will be populated from CSV data set config
If you need to send totally different JSON with each request it will make sense to put all the payload files into some folder and then:
Use Directory Listing Config to read the file paths into JMeter Variables
Use __FileToString() function for reading the file content into the HTTP Request body data
It's better to store POST data as separate JSON file. Here is how I would store:
- testdata
- json
- sample_file1.json
- sample_file2.json
There is advanced option if you don't like to store pre-defined JSON file for each test case but rather to generate one. You can use JSON Schema to generate JSON files, all you have to do is to create schema and generate JSON files based on that schema.
Is it possible to pass in file path or read from another file within csv? My test setup is something like that.
Jmeter Test
Http request -> body data -> "items": "${__property(${items})}",
CSV data config
Id,Name,Items
1,MyName,\input\items_json.txt
I want to include a file in csv items column and in jmeter test, it will read and post items json.
Got it working with this.
"items": ${__FileToString(${__property(${Items})},,)},
Not really, being a Configuration Element CSV Date Set Config is initialised before anything else so you will have to consider another approach, i.e.:
__CSVRead() function
__StringFromFile() function
__FileToString() function()
Functions are being evaluated exactly where they're called so this way you can use them for parameterization. See Apache JMeter Functions - An Introduction to learn more about JMeter Functions concept
URL format is
www.something.com/something/api/{uuid}?code=gomundw0gjq2kbvc3g63whfr9usap5rurjaq5vui5vm6xbt9hhqa8hbcpto4yatwpn26v42t9
I need to make several calls to this GET Url and check performance of the feature.
uuid here is not just the UUID , but is specific to my application
UUID= accountid+identifierid+uuid, which will look like 1234+1234+123e4567e89b12d3a456426655440000
How should I arrange my Jmeter Test Plan.
My Plan would be:
write UUID generated to a file
Using any preprocessor call the file from file and write program to append to a different value in the csv which is account/identifierid.
Please help on this, can some one explain how I should logically arrange my test plan and code to get data to parameterize my path in HTTP Request sampler.
Thanks in Advance
You need to get accountid+identifierid information stored into CSV file. This is something you need to do on your own.
You can use CSV Data Set Config in order to get the information from that file while your test is running, example configuration would be:
UUID can be generated using __UUID() function
So your HTTP Request sampler configuration would be something like:
