So I creating a scrolling function which looks like this

Feature: Dynamic page scrolling
Scenario: Scrolling function  
* def ScrollHeight = function(){return script("document.body.scrollHeight")
* def ScrollFunction = function(){ script("window.scrollTo(0,document.body.scrollHeight)")
* def ScrollingFunction = 
"""
function(){
var height = ScrollHeight()
while(true)
{ ScrollFunction()
var newHeight = ScrollHeight() 
if(height  === newHeight )
break;
height = newHeight 
} 
}
"""

So I created this in the same feature file in which I am having my test scenarios but I want to make this as a centralized function into another feature file from where I can use it in other feature files also. But I will not be able to call ScrollHeight and ScrollFunction from other feature files?

This is how I am trying this to create it in a new feature file Scrolling.feature

Feature: Dynamic page scrolling Function
Scenario: Scrolling function  
*def obj = read('classpath:Testing.feature')
* def ScrollingFunction = 
"""
function(){
var height = obj.ScrollHeight()
while(true)
{ obj.ScrollFunction()
var newHeight = obj.ScrollHeight() 
if(height  === newHeight )
break;
height = newHeight 
} 
}
"""

And my Testing.feature file looks like

Feature: Testing
Background:
* def ScrollHeight = function(){return script("document.body.scrollHeight")
* def ScrollFunction = function(){ 
script("window.scrollTo(0,document.body.scrollHeight)")}
Scenario: Test-1
* def fun = call read('classpath:Scrolling.feature')
* call fun.ScrollingFunction

But it does n't work for me

Reset to default

All the methods such as script() are available only after a driver has been instantiated by default. So make sure you declare any re-usable functions after the driver <url> step.

Else you have to do something like this for re-usability:

   * def getScrollHeight =
   """
   function() {
     var driver = karate.get('driver');
     return driver.script("document.body.scrollHeight");
   }
   """

If this is not working, please create a quickstart sample so that we can look into it: https://github.com/intuit/karate/tree/develop/examples/ui-test

Thanks for your time but that is not giving any error but is not doing the scrolling also @peter
@Ajex so follow the instructions
Sure, but can you please conform that obj.ScrollHeight() is it the correct way to call karate function in js code? @peter
I don't know. I have used other JS not this. why don't you just scroll to some element or div using developer.mozilla.org/en-US/docs/Web/API/Element/scrollIntoView
I tried this way but it doesn't worked in my case.Thanks for your suggestion.

You don't need to reference another function. It can be done in the same script.

This works for me:

Feature: Search Posts

  Background:
    * configure driver = { type: 'chrome', start: false }

    # build search endpoint
    * def buildSearch =
      """
      function() {
        var keys = 'fake%20news';
        var filter = 'eyJycF9jcmVhdGlvbl90aW1lIjoie1wibmFtZVwiOlwiY3JlYXRpb25fdGltZVwiLFwiYX'+
                     'Jnc1wiOlwie1xcXCJzdGFydF95ZWFyXFxcIjpcXFwiMjAyMFxcXCIsXFxcInN0YXJ0X21v'+
                     'bnRoXFxcIjpcXFwiMjAyMC0xXFxcIixcXFwiZW5kX3llYXJcXFwiOlxcXCIyMDIwXFxcIi'+
                     'xcXFwiZW5kX21vbnRoXFxcIjpcXFwiMjAyMC0xMlxcXCIsXFxcInN0YXJ0X2RheVxcXCI6'+
                     'XFxcIjIwMjAtOC0xMlxcXCIsXFxcImVuZF9kYXlcXFwiOlxcXCIyMDIwLTgtMTJcXFwifVwifSJ9';
        
        return 'https://m.facebook.com/search/posts/?q='+keys+'&epa=FILTERS&filters='+filter;
      }
      """

  Scenario: facebook search

    # Scroll down until no more pager
    # return null to keep looping
    * def fecthPage =
      """
      function() {
        var results = script("window.scrollTo(0, document.body.scrollHeight); document.querySelectorAll('#see_more_pager').length")
        return results == 0 ? results : null;
      }
      """

    # Print Post information
    * def permalinks = []
    * def getPost =
      """
      function(x, y, z) {
        var feat = x.script("_.getAttribute('data-ft');");
        var store = x.script("_.getAttribute('data-store');");
        if (feat && store) {
            feat = karate.toJson(feat);
            store = karate.toJson(store);
            karate.appendTo(permalinks, {'Features': feat, 'Store': store});
        }
      }
      """

    Given driver buildSearch()

    * waitUntil(fecthPage)
    * def posts = locateAll('//div[@data-store][@data-ft]')
    * karate.forEach(posts, getPost)
    * print "Posts:", permalinks

To avoid chrome profiles eating all my disk, I start it before karate.
That's why start: false
