How to read / fetch data from Json file

Performance Testing using JMeter

This video explains complete steps to Read or Get Data from JSON File in Jmeter. The JSON file will be present in test suite repository and we can read that file data and pass it to the request. To read the file we can write simple BeanShell script.

JSON body used the video :
{
"resourceType": "Patient",
"identifier": [ { "system": "urn:oid:1.2.36.146.595.217.0.1", "value": "123786" } ],
"name": [ {
"family": "Chalmers",
"given": [ "Peter", "James" ]
} ],
"gender": "male",
"birthDate": "1974-12-25"
}

Steps to achieve this :
1. Create a simple test suite and add a Post request
2. Add assertion and listener to validate the result
3. Add a Post Processor JSR223 Post Processor and write simple lines of code to read data from the JSON response

Hello sir,
Need to know if we have a GET request containing array object is it possible to store it in the similar manner that you explained?

Hello Sir,
First of all thanks for this knowledgeable content. I have one query that if the JSON file has one Order ID (unique) for an order creation and we are sending this request to the server for 1 user/1 iteration then the same is being accepted by the server but how to send the same multiple requests for multiple users having different Order ID in the JSON file with each request because server is only accepting unique Order ID with each request.
Your solution will be highly appreciated 🙂

you have knowledge but it is like you are not teaching you are telling some when what you have done people who are new cant understand
