Postman test save variable from JSON response body - postman

Question

I have json response body like this
{
"header": {
"process_time": "27.842975",
"server_time": "",
"reason": "",
"error_code": 0,
"status_code": 200
},
"data": {
"idx": "2",
"component": {
"id": 123,
"name": "product",
"properties": {
"button_notification": false
},
"title": "",
"data": [
{
"status": 4,
"product_id": 1112323,
"stock": 21
},
{
"status": 4,
"product_id": 1114322,
"stock": 13
},
{
"status": 4,
"stock": 8,
"product_id": 1115342
},
{
"stock": 5,
"status": 4,
"product_id": 1115234
},
{
"stock": 5,
"status": 4,
"product_id": 1115442
}
]
}
},
"errors": []
}
I want to save two product_id values which have the most two stock than other
here my code
var jsonData = JSON.parse(responseBody);
let productId-1 = jsonData.data.component.data[2].product_id
let productId-2 = jsonData.data.component.data[3].product_id
pm.environment.set("productId-1",productId-1)
pm.environment.set("productId-2",productId-2)

Answer 1

The most simple solution to your problem would be implementing bubble sort for finding the product with the most stock.
let arr = jsonData.data.component.data;
for(let i = 0; i < arr.length - 1; i++){
for(let j = 0; j < arr.length - 1 - i; j++){
if (arr[j].stock < arr[j+1].stock) {
let temp = arr[j];
arr[j] = arr[j+1];
arr[j+1] = temp;
}
}
}
pm.environment.set("productId-1", arr[0]); //product with most stock
pm.environment.set("productId-2", arr[1]); //product with second most stock
