Use conditional logic in Scenario Outline with lists

Question

We use karate 0.9.5. We would like to make a dynamic Scenario Outline using conditional logic. We would like to retrieve towns for a list of regions, and this for a list of countries. Conditional logic is used only in towns retrieving. What we've done:

Main.feature:

Scenario Outline:
* def countries = call read('GetRegionsWithTowns.feature') { countryId: '#(<id>)' }
Examples:
  |countriesList|

GetRegionsWithTowns.feature:

Scenario:
* def fun =
  """
  function(regions) {
    for (i = 0; i < regions.length; i++) {
      var region = regions[i];
      if(region['name'] && region['name'].contains('alabama')){
        karate.log('***smth');
      }
      else{
        var regionId = region['region_id'];
        karate.call('GetTowns.feature', [regionId]);
      }
    }
  }
  """
* def regions = call read('GetRegions.feature') { countryId: '#(countryId)' }
* def result = call fun(regions)

GetRegions.feature

Scenario:
 Given url 'someurl'
 And path countryId, 'regions' 
 When method get
 Then status 200

GetTowns.feature

Scenario:
 Given url 'someurl'
 And path regionId, 'towns'
 When method get
 Then status 200

Error is

 GetTowns.feature:16 (the line with "And path regionId, 'towns'") - javascript evaluation failed: regionId, ReferenceError: "regionId" is not defined in <eval> at line number 1

We can't figure out what we are doing wrong? Any help is welcome, thanks

I think this is the change needed:

karate.call('GetTowns.feature', { regionId: regionId });

I do think you are grossly overcomplicating your tests.

I would try to avoid call as far as possible.
Any variables defined in parent features will be visible to "called" features, so you don't need to pass all data as arguments
Avoid JS code especially loops as far as possible, refer: https://github.com/intuit/karate#loops

Thank u so much @Peter Thomas, but how we can simplify this test? We need to iterate in amount of countries, regions, towns, which is dynamic and we need a condition in towns retrieving. – cygne Mar 31 '20 at 07:49
@cygne just my opinion and I don't understand your scenario because it is so complex. sometimes you should just hard-code your input and output data for simpler tests, best explained here: https://stackoverflow.com/a/54126724/143475 – Peter Thomas Mar 31 '20 at 07:51
