Using karate-config parameters in a feature file

Question

The karate header examples do not show how to access config values other than baseUrl. When I switch environments (passing in -Dkarate.env=qual as part of the run command) then baseUrl is set correctly.

The problem is, I want to use other config values as shown here but when I run the test, it fails to access config.ApiKey correctly. Instead I get this error

My .feature file and karate-config.js are below.

XYZ.feature

@regression
Feature: Checkdigit Algorithm API

Background:
* url baseUrl
* def secretKey = config.apiKey
* configure ssl = true

Scenario Outline: Testing XYZ algorithm

* configure headers = { KeyId: secretKey, Accept: 'application/json' }
Given path 'headers'
And param url = baseUrl
And params { customerId: '<custcode>', algoId: '<algo>' }
When method get
Then status <val>

Examples:
  | algo   | custcode      | val   | comment |
  | XYZ    | 2110974841    | 204   | Valid |
  | XYZ    | 7790011614    | 204   | Valid |
  | XYZ    | 5580015174    | 204   | Valid |
  | XYZ    | 2110974840    | 400   | expected check digit 1 |
  | XYZ    | 211097484     | 400   | not 10 digits |
  | XYZ    | 211097484x    | 400   | not numeric |    

karate-config.js

function() {    
  //set up runtime variables based on environment
  //get system property 'karate.env'
  var env = karate.env;
  if (!env) { env = 'dev'; }  // default when karate.env not set

  // base config
  var config = {
    env: env,
    baseUrl: 'https://localapi.abc123.example.com/api/v1/validate/customerid',
    apiKey: ''
  }
  //switch environment
  if (env == 'dev') {
  config.baseUrl = 'https://devapi.abc123.example.com/api/v1/validate/customerid';
  config.apiKey  = 'fake-1ba403ca8938176f3a62de6d30cfb8e';
  } 
  else if (env == 'qual') { //Pre-production environment settings
  config.baseUrl = 'https://qualapi.abc123.example.com/api/v1/validate/customerid';
  config.apiKey  = 'fake-d5de2eb8c0920537f5488f6535c139f2';
  }

  karate.log('karate.env =', karate.env);
  karate.log('config.baseUrl =', config.baseUrl);
  karate.log('config.apiKey =', config.apiKey);

  return config;
}

(similar issue here, using a separate headers.js: https://github.com/intuit/karate/issues/94)

Answer 1

Keep in mind that all the keys within the JSON object returned by karate-config.js will be injected as variables, and nothing else. So you will not be able to refer to config, but you will certainly be able to refer to apiKey.

I think if you make this simple change, things will start working:

* def secretKey = apiKey

Also, I think you have a problem in the first line of the scenario, it should be:

* configure headers = { KeyId: '#(secretKey)', Accept: 'application/json' }
