My config File Code :

 function () { var System = Java.type('java.lang.System'); var env = System.getProperty("profile"); if (!env) { karate.log('env is not defined.') env = 'dev'; } var request = new XMLHttpRequest(); request.open("GET", "http://www.testsite.com",false); request.send(); var result = request.responseText; console.log(result); return result } 

Answer 1

var request = new XMLHttpRequest();

Sorry, that's not going to work. Karate supports just ES2015 and plain JS.

Also:

request.open("GET", "http://www.testsite.com",false);

That's totally un-necessary, since Karate's speciality is making HTTP requests ! Please read the docs more carefully. For example you can do this in a *.feature file:

Feature:

Scenario:
Given url 'http://www.testsite.com'
When method get
Then status 200
And def result = response
And print result

And are you sure you have to do this in karate-config.js ? Sounds like you are completely new to Karate - but if so, you can do: var result = karate.call('my.feature'); .

Answer 2

I also have the same issue. Because I want to send notice when Scenario execute failed, like this:

Feature:

  Background:
    * url baseApi
    * configure afterScenario =
    """
    function() {
      if (karate.info.errorMessage != null) {
        callback();
      }
    }
    """
    * configure retry = { count: 3, interval: 3000 }

  Scenario: get it (ERROR)
    * def input =
    """
    {
      'form': {
        'id': '123509638998',
        'td': '5xm6ksy6ty2jqam',
        'nd': '0'
      },
      'query': {
      }
    }
    """
    * path '/rest/n/list'
    * params input.query
    * form fields input.form
    * retry until responseStatus == 200
    * method post
    * match response contains { result: 1 }

And karate-config.js like this:

function() {
  karate.configure('connectTimeout', 5000);
  karate.configure('readTimeout', 5000);
  var url = 'http://127.0.0.1:8088';
  if (karate.properties['apiServer'] != '') {
    url = karate.properties['apiServer'];
  }

  var config = {
    apiBaseUrl: url,
    callback: function() {
      var url = 'https://x.y.z.com/api/send?access_token=257def70cab07fda4e93efeae04c497d';

      var data = JSON.stringify({
        'id': '123',
        'msgtype': 'text',
        'text':{
          'content': 'Test message...'
        }
      });

      fetch(url, {
        headers: { "Content-Type": "application/json; charset=utf-8" },
        method: 'POST',
        body: data
      })
    }
  };

  return config;
}
