Json response validation based on substring presence in Karate Framework [duplicate] - json

Question

This question already has an answer here:
Karate API json response - How to validate the presence of a key which sometimes come and sometimes not in the API response
(1 answer)
Closed 2 years ago.
I am trying to validate a JSON which has Optional keys depending on a condition.
Json response is as follows:
{ "hits": [
{
"_type": "sessions",
"_source": {
"movie_name": "The Greatest Showman (U/A) - English",
"session_data": {
"freeSeating": false,
"mandatoryItems": [],
"areas": [
{
"seatingType": "fixed"
},
{
"seatingType": "free"
},
{
"seatingType": "mixed"
}
]
}
}
},
{
"_type": "sessions",
"_source": {
"movie_name": "The Greatest Showman (U/A) - English",
"session_data": {
"freeSeating": false,
"mandatoryItems": [],
"areas": [
{
"seatingType": "fixed"
},
{
"seatingType": "free"
}
]
}
}
},
{
"_type": "sessions",
"_source": {
"movie_name": "The Greatest Showman 3D (U/A) - English",
"session_data": {
"freeSeating": false,
"mandatoryItems": [
{
"quantity": 1,
"level": "ticket",
"price": 30,
"type": "3dglasses"
}
],
"areas": [
{
"seatingType": "fixed"
}
]
}
}
}
]
}
If movie_name contains "3D" in it then mandatoryItems = [{"quantity": 1,"level": "ticket", "price": 30, "type": "3dglasses"}]
If movie_name does not contains "3D" in it then mandatoryItems = []
I want to achieve above assertions in my feature file.
Note: "movie_name" and "mandatoryItems" are present each element of an array. So I want to assert this condition on entire array.
Thanks in advance!!

Sorry #Peter for the inconvenience caused by me. I worked on this problem statement by referring all possible sources and wrote following code which is giving me desired output:
Given url api_url
When method Get
And def mandatoryItems_present =
"""
{
"quantity": 1,
"level": "ticket",
"price": '#number',
"type": "3dglasses",
}
"""
Then status 200
And print response
And def source_list = karate.jsonPath(response, '$.._source')
And print source_list
And match each source_list[*].session_data contains {'freeSeating': '#boolean','mandatoryItems':'##[] mandatoryItems_present'}
And def movie_names = get source_list[*].movie_name
And def mandatoryItems_list = get source_list[*].session_data.mandatoryItems
And def name_size = names.size();
And print name_size
And def threeD_movie_list = new ArrayList()
And eval for(var i = 0; i < name_size; i++) {if (names[i].match('3D')) threeD_movie_list.add(names[i])}
And print threeD_movie_list
And def threeD_movies_array_size = threeD_movie_list.size();
And print threeD_movies_array_size
And print expected
And def expected = (threeD_movies_array_size == 0 ? {"mandatoryItems" : []} : {'mandatoryItems' : [mandatoryItems_present]} )
And print expected
And match each response.hits[*]._source.session_data[*].mandatoryItems == expected
Please let me know whether this approach is correct.
