How to add Multiple JSON array Element depends on Example Data Set - karate

Question

During my Karate scenario automation got the below problem statement. Could anyone please help me on this?
My JSON file will contain,
{
"schema_id": 25,
"records": [
{
"value": {
"NUM_CHARGE_ID": "#(numChargeID)",
"DTE_START": "2017-05-26",
"NUM_DAY": "#(numDay)"
}
}
]
}
From my Karate feature file I want to pass data from Example and depends on the data set it should create multiple array element in the json. Like,
Examples:
| numChargeID | numDay|
|C10,C21,C15,C18|1,2,3,4|
{
"schema_id": 25,
"records": [
{
"value": {
"NUM_CHARGE_ID": "C10",
"DTE_START": "2017-05-26",
"NUM_DAY": "1"
},
{
"NUM_CHARGE_ID": "C21",
"DTE_START": "2017-05-26",
"NUM_DAY": "2"
},
{
"NUM_CHARGE_ID": "C15",
"DTE_START": "2017-05-26",
"NUM_DAY": "3"
},
{
"NUM_CHARGE_ID": "C18",
"DTE_START": "2017-05-26",
"NUM_DAY": "4"
}
}
]
}
Is there any way in Karate that i can handle this type of situation?

Answer 1

There are plenty of ways to solve this and maybe you shouldn't try to force everything into Examples:. For instance:
* def chargeIds = ['C1', 'C2']
* def dayNums = [1, 2]
* def fun = function(x, i){ return { NUM_CHARGE_ID: x, NUM_DAY: dayNums[i] } }
* def records = karate.map(chargeIds, fun)
* print records
Which gives you:
[
{
"NUM_CHARGE_ID": "C1",
"NUM_DAY": 1
},
{
"NUM_CHARGE_ID": "C2",
"NUM_DAY": 2
}
]
What I would recommend is something like this:
* table records
| NUM_CHARGE_ID | NUM_DAY |
| 'C1' | 1 |
| 'C2' | 2 |
* print records
Which gives you the exact same thing.
Also look at the possible use of set: https://github.com/intuit/karate#set-multiple
