recently I started working with Karate and Yaml for the first time. I was able to validate simple response structures where all the answer data were on the same level. But now I have to validate a more complicated structure and I spent a lot of time without success.
When I perform a GET request I receive the next answer:
[
{
"factories": [
{
"id": 1,
"scopes": [
{
"id": null,
"name": "name 1",
"expireD": 10,
"isExpired": true
}
],
"companyName": "TEST",
},
{
"id": 2,
"scopes": [
{
"id": null,
"name": "name 2",
"expireD": 7,
"isExpired": true
}
],
"companyName": "TEST2",
}
],
"scopeId": null
}
]
The structure validation is not directly in the karate code. It is on a yml file like this:
operationId: getTest
statusCode: 200
params:
body: null
matchResponse: true
responseMatches:
scopeId: '##number'
factories:
companyName: '#string'
id: '#number'
scopes:
expireD: '#number'
name: '#string'
id: '#null'
isExpired: '#boolean'
I review the structure around 100 times and I have the same error all the time when I arrive here:
* match response contains responseMatches
The error is the next one: $[1].factories | data types don't match (LIST:MAP)
I tried to use match each, ignore one by one the structures to see which one is failing and also reduce the validations as #array and it is not working.
Any help will be more than welcome. Thank you.
Finally, a solution was found. The Karate documentation offers an idea about how to use it defining a structure of data that could be used as a type. I tried before but I added before the responseMatches section. The yml file looks like this:
operationId: getTest
statusCode: 200
params:
body: null
matchResponse: true
responseMatches:
scopeId: '##number'
factories: '#[_ <= 5] factoryStructure'
factoryStructure:
companyName: '#string'
id: '#number'
scopes: '#[] scopeStructure'
scopesStructure:
expireD: '#number'
name: '#string'
id: '#null'
isExpired: '#boolean'
