Appium protractor: getMultiCapabilities with list of devices as JSON

[raguravindran]

All,
I have a problem to solve.
Say I want to add multiple devices dynamically, Input from a JSON file as below

{
“Emulator” : [
{
“platformName” : “Android”,
“platformVersion”: “8.1.0”,
},
{
“platformName” : “Android”,
“platformVersion”: “7.1.1”,
}]
}

I want to create my capabilities based on this JSON object.
I am unable to come up with an approach to inject these JSON instances into getMultiCapabilities properties.
I am stuck here, after which i thought i will ask to appium experts if I can get some recommendations.

exports.config = {
seleniumAddress : url,
framework: “jasmine”,
getPageTimeout: 30000, // increase timeout alloted for page load, fixes issues with deep link logins in Firefox

getMultiCapabilities : function () {
    var multiCapabilities = [];
    var count = 0;
    var deferred = q.defer();
    
    for (var list in Dlist) {
        if (list.toUpperCase == 'EMULATOR') {
            for (var emulator in list) {
                q.resolve([{ "platformName": emulator.platformName}]);
            }
        }
    }
    return deferred.promise;
},

specs: [‘firstSpec.js’]
}

Any help would be greatly appreciated.
