How to loop over array values in a karate feature

Question

I am trying to loop over array values in a karate feature file. In a Feature1.feature - Scenario1, I have some values in the array ["UUID1","UUID2","UUID3"] and I want to call another feature file (Feature2.feature) (having a code to call a DELETE endpoint) of a service

Feature2.feature:

 @ignore

Feature: Delete

  Background:

    * url baseUrl
    * headers {content-type:'application/json'}

  Scenario: Delete Test Assets

    Given headers {uid: '#(UId)', cid:'#(CId)'}
    And path 'type', Type, 'id', AssetId
    When method delete
    Then status 204

What approach should I use to Feature1.feature to call the Feature2.feature in a loop?

Answer 1

If you have an array of primitives, you need to convert it into an array of JSON objects before doing a "loop call". Refer to the docs for karate.mapWithKey(): https://github.com/intuit/karate#json-transforms

So do this:

* def data =  ["UUID1","UUID2","UUID3"]
* def data = karate.mapWithKey(data, 'uid')
* call read('second.feature') data

And in second.feature:

* headers { uid: '#(uid)' }

Of course, read the docs for call if needed: https://github.com/intuit/karate#data-driven-features
