Pass Json to karate-config.js file

Question:

I have more than 6 environments against which i have to run the same set of rest api scripts. For that reason i have stored all that test data and the end points/resource paths in a json file. I then try to read this json file into my karate-config.js file, this is because i want to fetch the data corresponding to the environment that is being passed from the command line (karate.env), which am reading into my karate-config.js file

Below is my json file sample

[ { "qa":{ "username_cm_on":"test_cm_on_qa", "password_cm_on":"Test123$", "nonadmin_username_cm_on":"test_non_admin_cm_on_qa", "nonadmin_password_cm_on":"Test123$", "username_cm_off":"test_cm_off_qa", "password_cm_off":"Test123$", "nonadmin_username_cm_off":"test_non_admin_cm_off_qa", "nonadmin_password_cm_off":"Test123$", "zuul_urls":{ "home-sec-uri":"https://qa.abc.com/qa/home-sec-uri", "home-res-uri":"https://qa.abc.com/qa/home-res-uri" } } }, { "uat":{ "username_cm_on":"test_cm_on_uat", "password_cm_on":"Test123$", "nonadmin_username_cm_on":"test_non_admin_cm_on_uat", "nonadmin_password_cm_on":"Test123$", "username_cm_off":"test_cm_off_uat", "password_cm_off":"Test123$", "nonadmin_username_cm_off":"test_non_admin_cm_off_uat", "nonadmin_password_cm_off":"Test123$", "zuul_urls":{ "home-sec-uri":"https://uat.abc.com/qa/home-sec-uri", "home-res-uri":"https://uat.abc.com/qa/home-res-uri" } } } ]

and below is my karate-config.js file

function() { // var env = karate.env; // get system property 'karate.env' var env = 'qa'; var cm = 'ON'; var envData = call read('classpath:env_data.json'); //require("./env_data.json"); // write logic to read data from the json file _ Done, need testing karate.log('karate.env system property was:', env); switch(env) { case "qa": if(cm === 'ON'){ config.adminusername_cm_on = getData().username_cm_on; config.adminpassword_cm_on = ""; config.nonadminusername_cm_on = getData().nonadmin_username_cm_on; config.nonadminpassword_cm_on = ""; }else if(cm === "OFF") { config.adminusername_cm_off = getData().username_cm_off; config.adminpassword_cm_off = ""; config.nonadminusername_cm_off = getData().nonadmin_username_cm_off; config.nonadminpassword_cm_off = ""; } break; case "uat": break; default: break; } // This method will return the data from the env_data.json file var getData = function() { for(var i = 0; i < obj.length; i++) { for(var e in obj[i]){ var username_cm_on = obj[i][e]['username_cm_on']; var nonadmin_username_cm_on = obj[i][e]['nonadmin_username_cm_on']; var username_cm_off = obj[i][e]['username_cm_off']; var nonadmin_username_cm_off = obj[i][e]['nonadmin_username_cm_off']; return { username_cm_on: username_cm_on, nonadmin_username_cm_on: nonadmin_username_cm_on, username_cm_off: username_cm_off, nonadmin_username_cm_off: nonadmin_username_cm_off } } } } var config = { env: env, data: getData(), } return config; }

I tried several ways to load the env-data.json file into karate-config.js as below

var envData = call read('classpath:env_data.json');

I know the above is not valid from this stackover flow answer <a href="https://stackoverflow.com/a/47041833/2053577" rel="nofollow">Karate - How to import json data</a> by <a href="https://stackoverflow.com/users/143475/peter-thomas" rel="nofollow">Peter Thomas</a>

So,tried with the below ones

var envData = read('classpath:env_data.json'); var envData = require("./env_data.json"); var envData = require('./env_data.json');

But, still facing issues with reading the json file. Appreciate help on this.

Answer1:

I think you over-complicated your JSON. You just need one object and no top-level array. Just use this as env_data.json:

{ "qa":{ "username_cm_on":"test_cm_on_qa", "password_cm_on":"Test123$", "nonadmin_username_cm_on":"test_non_admin_cm_on_qa", "nonadmin_password_cm_on":"Test123$", "username_cm_off":"test_cm_off_qa", "password_cm_off":"Test123$", "nonadmin_username_cm_off":"test_non_admin_cm_off_qa", "nonadmin_password_cm_off":"Test123$", "zuul_urls":{ "home-sec-uri":"https://qa.abc.com/qa/home-sec-uri", "home-res-uri":"https://qa.abc.com/qa/home-res-uri" } }, "uat":{ "username_cm_on":"test_cm_on_uat", "password_cm_on":"Test123$", "nonadmin_username_cm_on":"test_non_admin_cm_on_uat", "nonadmin_password_cm_on":"Test123$", "username_cm_off":"test_cm_off_uat", "password_cm_off":"Test123$", "nonadmin_username_cm_off":"test_non_admin_cm_off_uat", "nonadmin_password_cm_off":"Test123$", "zuul_urls":{ "home-sec-uri":"https://uat.abc.com/qa/home-sec-uri", "home-res-uri":"https://uat.abc.com/qa/home-res-uri" } } }

And then this karate-config.js will work:

function() { var env = 'qa'; // karate.env var temp = read('classpath:env_data.json'); return temp[env]; }

And your tests can be more readable:

Given url zuul_urls['home-sec-uri']
