How to call a particular javascript function from .js file in karate feature file

Question

Suppose I have saved followings functions in a Utility js file.

function getCurrentDate(){
return 'date';
}

function getMonth(){

return 'Oct';
}

Please help me how any of these methods can be accessed in feature file.

I tried following code but it is not working.

* def fun = call read('Utility.js')

* def result = getData()
or
* def result = fun.getData()

In Karate, a JS file can contain only one function and it does not need a name, take a closer look at the examples.

I don't really recommend combining multiple functions into one file, it just makes things much harder to maintain. But if you really insist, here's how:

function() {
  return {
    getCurrentDate: function(){ return 'date' },
    getMonth: function(){ return 'month' }
  }
}

But maintaining too many files of js will be overhead . Provided solution is also not a good approach in terms of readability.

just create one feature file that has as many in-line JS functions as you want declared and re-use it. done !

Feature file will also be fine. However , do we have any way to reuse particular function from a feature file having many java script function? I have checked documentation but not able to figure it out.

really not sure what you are concerned about, split your features depending on what you want to re-use. if some JS is declared and not used, it is ok, why are you worried ?

You can call def functions = call read('classpath:reusable.js') and in same feature file try def x = functions.getCurrentDate( ). Hope this helps others trying to figure out on calling custom functions that are in javascript file.

* def data = karate.read('classpath:<path>/getRandomString.js')(<inputToTheFunctionIfAny>);

The above code works.
