Simulating Cordova plugin functionality during unit testing

Question

Simulating Cordova plugin functionality during unit testing

I have a code snippet that I need to test in my controller:

$scope.fbLogin = function() {
  console.log('Start FB login');
  facebookConnectPlugin.login(["public_profile", "email", "user_friends"], FacebookServices.fbLoginSuccess, FacebookServices.fbLoginFailure);
};

The facebookConnectPlugin does not require injection into the controller. By adding

cordova plugin add cordova-plugin-facebook4

, the facebookConnectPlugin becomes globally accessible.

In unit tests, the facebookConnectPlugin is not available for mocking since it doesn't need to be injected using the $provide.value() method anymore.

Here is the error message displayed in both the source code and specs:

ReferenceError: facebookConnectPlugin is not defined at Scope.$scope.fbLogin (/app/signup-and-login/controllers.js:9:6120)

ReferenceError: facebookConnectPlugin is not defined at Object. (/app/signup-and-login/signup-specs.js:93:9)

Could someone help me understand how to mock the plugin and provide it in the unit testing environment?

Encountered a similar issue and was able to resolve it by adding a globals.js file to the karma.config.js in the files array. Inside the globals.js file, I defined a facebookConnectPlugin global object with login and logout functions as shown below:

globals.js

facebookConnectPlugin = {
  login: function(){...},
  logout: function(){...}
};

and then included this in the karma.config.js

// Karma configuration
module.exports = function(config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine'],

    files: [
      'www/assets/lib/angular/angular.js',
      'node_modules/jquery/dist/jquery.min.js',
      'node_modules/jasmine-jquery/lib/jasmine-jquery.js',
      'node_modules/angular-mocks/angular-mocks.js',
      ...
      //// MOCK GLOBALS ///////////////////
      'test/mocks/globals.js',
      /////////////////////////////////////
      ...
    ],
    ...
};
