Cannot match schema from a file which has nested array [duplicate] - karate

Question

This question already has an answer here:
Karate Tests: How to match contains each nested array response with just one schema
(1 answer)
Closed 1 year ago.
Assume that I have a response-Json look like below
def resJson =
"""
{
"id": 1,
"code": "OU82883",
"features":
[
{
"id": 12,
"class": "OU8811",
"school": "parent",
"course": "abc",
"sortOrder": 123
}
]
}
"""
To be easily manage file to compare, I am placing the expected schema - expected result in a file ("getCourseDetails.txt"), with structure below
{
id: '#number',
code: '#string',
features: ##[{
id: '#number',
class: '##string',
school: '##string',
course: '##string',
sortOrder: '#number'
}
]
}
Then in executed feature file, perform the code as
* json expSchema= read ('../Data/Schema/getCourseDetails.txt')
* match resJson == expSchema
The system informs AssertionFailed Error
To find another way to validate schema, I kept only the structure inside of "features" in "getCourseDetails". The outside of "features", I put into executed feature file. So my code now is:
GetCourseDetails file:
{
id: '#number',
class: '##string',
school: '##string',
course: '##string',
sortOrder: '#number'
}
Feature file:
* json courseDetails= read ('../Data/Schema/getCourseDetails.txt')
* def expSchema = {id: '#number', code: '#string', features: '##[] courseDetails'}
* match resJson == expSchema
There is no error and validate works well, but this approach is not my expected.
I would like to know is there a way to centralize all things in a file, and user just calls the file to validate against actual response's schema
Thank you so much.

I think you are over-engineering your tests, but you can use JS to do advanced set-up and building the schema the way you want, and it will be re-usable. For example:
first.json:
{ "foo": "#string" }
second.json:
{ "value": "#number" }
schema.js:
function() {
var first = read('first.json');
karate.set('second', read('second.json'));
first.bar = '##[] second';
return first;
}
now your feature file can be:
* def schema = call read('schema.js')
* def response = { foo: 'test', bar: [{value: 1}, {value: 2}] }
* match response == schema
Above, if you * print schema you will see:
{
"foo": "#string",
"bar": "##[] second"
}
And if you want a one-liner - * match response == call read('schema.js') should work !
