Error: Jasmine test is encountering an undefined controller

karma.config.js:

module.exports = function(config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine'],
    files: [
      'node_modules/angular/angular.min.js',
      'node_modules/angular-mocks/angular-mocks.js',
      'node_modules/angular-translate/dist/angular-translate.min.js',
      'browser/javascripts/*.js',
      'browser/tests/*.spec.js'
    ],
    exclude: [],
    preprocessors: {},
    reporters: ['progress'],
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    browsers: ['Chrome'],
    singleRun: false,
    concurrency: Infinity
  })
};

home.spec.js:

describe('Home Controller', function() {
  beforeEach(
    module('pascalprecht.translate'),
    module('tradeshiftApp')
  );
  var $controller;
  beforeEach(inject(function(_$controller_){
    $controller = _$controller_;
  }));

  it('should exist', function(){
    controller = $controller('HomeController', {
      $scope: {}
    });
    expect(controller).not.toBe(undefined);
  })
});

I am utilizing karma-jasmine and encountering an issue. When I try to mock my controller defined in the app.js file, as shown below:

var app = angular.module('tradeshiftApp', ['pascalprecht.translate']);

An error is thrown stating that HomeController is not recognized as a function. Despite ensuring all dependencies are correctly set up, this unexpected behavior occurs. Any insights or suggestions would be greatly appreciated.

Note: A successful injection of $rootScope using $rootScope.$new() has been attempted.

Answer №1

Here is a helpful suggestion:

beforeEach(function() {
      angular.module('pascalprecht.translate', [])
      angular.mock.module('myApp')
   }
);

Answer №2

It turns out that the issue stemmed from the 'pascalprecht.translate' module in my code. I had a minor dependency linked to this module in my HTML file, but neglected to include it in my Karma config file. Lesson learned: always be cautious and attentive when working on your code :)
