Answer 1

EDIT: after this question, we decided to add the option to karate.setupOnce() that achieves this in a more elegant way: https://github.com/karatelabs/karate/issues/2210

Here is your solution. You can run it and see for yourself.

Feature:

@setup
Scenario:
* def fun = function(){ karate.log('function executed'); return [{a: 1}, {a: 2}] }
* def data = callonce fun

Scenario Outline:
* print 'first:', __row

Examples:
| karate.setup().data |

Scenario Outline:
* print 'second:', __row
    
Examples:
| karate.setup().data |
