I would like to print the index value for matching JSON data using Karate.
For below code the expected answer should be 2, but I got -1, not sure what I am missing
[
{"aaa": 101},
{"bbb": 102},
{"ccc": 103}
]
Feature: Rough
Scenario: Rough
* def myData = read('roughTestData.json')
* print "Index ->>", myData.indexOf('ccc')
You have a JSON object within an array (not a plain string), and the complication here is you are interested in keys not values, so you need to do this instead:
* def response = [{"aaa":101},{"bbb":102},{"ccc":103}]
* def keys = response.map(x => Object.keys(x)[0])
* def index = keys.indexOf('ccc')
* match index == 2
We are using JS array methods such as map(), Object.keys() and indexOf() above
That said, I personally think you are over-complicating things because Karate allows you to match without caring about the order. For example:
* def response = [{"aaa":101},{"bbb":102},{"ccc":103}]
* def expected = [{ccc:'#number'},{bbb:'#number'},{aaa:'#number'}]
* match response contains only expected
So read the docs, and be creative: https://github.com/karatelabs/karate#json-arrays
