Comparing two JSON objects with order of fields and subarrays shuffled in Karate [duplicate] - karate

Question

This question already has an answer here:
Asserting and using conditions for an array response in Karate
(1 answer)
Closed 2 years ago.
I want to loop through below nested json structure and want to update all the required fields, however I could achieve this through typescript but want to do this in karate JS, I do not see any examples how to nested for each works.
I want to update 26 periods data(here for readability i used 3), based on index I want to update period field, i.e. if(index == key), these 26 periods are under each car attribute.(NOTe: you again have multiple cars and multiple car attributes and each car attribute you have 26 periods data)
I cannot use this Karate - Match two dynamic responses only when you have single array list and have less data
[
{
"cars": [
{
"name": "car 1",
"periodsData": [
{
"period": "5ed73ed31a775d1ab0c9fb5c",
"index": 1
},
{
"period": "5ed73ed31a775d1ab0c9fb5d",
"index": 2
},
{
"period": "5ed73ed31a775d1ab0c9fb5e",
"index": 3
}
]
},
{
"name": "car 2",
"periodsData": [
{
"period": "5ed73ed31a775d1ab0c9fb5c",
"index": 1
},
{
"period": "5ed73ed31a775d1ab0c9fb5d",
"index": 2
},
{
"period": "5ed73ed31a775d1ab0c9fb5e",
"index": 3
}
]
},
{
"name": "car 3",
"periodsData": [
{
"period": "5ed73ed31a775d1ab0c9fb5c",
"index": 1
},
{
"period": "5ed73ed31a775d1ab0c9fb5d",
"index": 2
},
{
"period": "5ed73ed31a775d1ab0c9fb5e",
"index": 3
}
]
}
],
"totalPeriodEprps": [
{
"period": "5ed73ed31a775d1ab0c9fb5c",
"index": 1
},
{
"period": "5ed73ed31a775d1ab0c9fb5d",
"index": 2
},
{
"period": "5ed73ed31a775d1ab0c9fb5e",
"index": 3
}
]
}
carId ="dfd"
]
This above array repeats
Type script code
//periods is a map of index and values
async modifyCarsData(mid, id, periods, campaignData) {
//carData is a json file
carData.forEach(element => {
element.carId= id;
// Update all egrp periods
element.totalPeriodEGRPs.forEach(eGrpPeriod => {
// egrprd.period =
if (periods.size === element.totalPeriodEGRPs.length) {
periods.forEach((value, key) => {
if (key === eGrpPeriod.index.toString()) {
eGrpPeriod.period = value;
return true;
}
});
}
});
element.cars.forEach(carCell => {
// Logic for updating periods data
carCell .periodsData.forEach(periodAttribute => {
if (periods.size === carCell.periodsData.length) {
periods.forEach((value, key) => {
if (key === periodAttribute.index.toString()) {
periodAttribute.period = value;
return true;
}
});
}
});
});
});

Don't think of this as an update, but as a transform. I'm not using your example because it is un-necessarily complicated. Here is a simpler example that gives you all the concepts you need:
* def data = [{ name: 'one', periods: [{ index: 1, value: 'a' },{ index: 2, value: 'b' }]}, { name: 'two', periods: [{ index: 1, value: 'c' },{ index: 2, value: 'd' }]}]
* def fnPeriod = function(x){ x.value = x.value + x.index; return x }
* def fnData = function(x){ return { name: x.name, periods: karate.map(x.periods, fnPeriod) } }
* def converted = karate.map(data, fnData)
* print converted
Which prints:
[
{
"name": "one",
"periods": [
{
"index": 1,
"value": "a1"
},
{
"index": 2,
"value": "b2"
}
]
},
{
"name": "two",
"periods": [
{
"index": 1,
"value": "c1"
},
{
"index": 2,
"value": "d2"
}
]
}
]
If this doesn't work for you, please look for another tool. Karate is designed for testing and assertions, not doing what you normally do in programming languages. And I suspect that you have fallen into the trap of writing "over-smart tests", so please read this: https://stackoverflow.com/a/54126724/143475
