Karate: Get all users and delete with the reference id - karate

Question

After my tests are completed, I would like to delete all the users that were created. I am able to delete one user at a time. Can we do this using conditional logic?
Feature file:
Given path 'users'
And header Authorization = authId
And header Accept = 'application/json;version=2'
When method Get
Then status 200
Then print 'Response Time: '+ responseTime + ' milliseconds'
* def resp = $
* def size = karate.sizeOf(resp)
* print 'Number of users: ' + size
This gives me below response:
[
{
"firstName": "Edit User",
"lastName": "API Test",
"emailAddress": "edituserapitesting#gmail.com",
"ada": true,
"isDeleted": false,
"alerts": [],
"links": [
{
"href": "https://someurl/api/users/0219360d-5ca6-42af-9e9c-10be1e32d219",
"rel": "self"
}
]
},
{
"firstName": "Create",
"lastName": "Test",
"emailAddress": "api#test.com",
"ada": true,
"isDeleted": false,
"alerts": [],
"links": [
{
"href": "https://someurl/api/users/5e3c9be1-2863-4a2d-85e9-966582b127ac",
"rel": "self"
}
]
},
{
"firstName": "Create",
"lastName": "Test",
"emailAddress": "api#test.com",
"ada": true,
"isDeleted": false,
"alerts": [],
"links": [
{
"href": "https://someurl/api/users/b6feb126-bca2-43e6-ba2d-87aaae81fef0",
"rel": "self"
}
]
},
{
"firstName": "Create",
"lastName": "Test",
"emailAddress": "api#test.com",
"ada": true,
"isDeleted": false,
"alerts": [],
"links": [
{
"href": "https://someurl/api/users/4f07f234-9606-4cf5-94ce-3a42fb11a6d7",
"rel": "self"
}
]
}
]
I have to get the id [Eg:4f07f234-9606-4cf5-94ce-3a42fb11a6d7] from each json and pass it to delete path.

Please read about transforms: https://github.com/intuit/karate#json-transforms
Now in one line you can get an array of ids:
* def ids = karate.map(response, function(x){ var link = x.links[0].href; return link.substring(link.lastIndexOf('/') + 1) })
Now you can use this in a loop or data driven test and do what you want.
