Creating effective test cases for Angular JS controllers

Our team has recently taken on the task of writing test cases for our application, specifically focusing on controllers. Utilizing Mocha, Chai, and Sinon libraries, we are looking for guidance on how to effectively write these test cases.

We have shared a plunker link that contains the code for our controller. Can anyone provide assistance in creating test cases for this controller? Our ultimate goal is to implement these test cases for other controllers based on the initial push with this one.

Below is the code snippet:

angular.module('ngBoilerplate.account', [
    'ui.router', 'ngAnimate', 'ui.bootstrap', 'ngBoilerplate.contact', 'ngResource', 'jcs-autoValidate', 'ngCookies', 'ngTagsInput'
])
.controller('addAccount', function($scope, industryService, $http, $state, LoggedUser) {
    // Controller logic here
})
.factory("loggedInUser", function($resource) {
    return $resource("/rest/users/:username");
})
 .factory("industryService", function($resource) {
    return $resource("/rest/accounts/industry");
})

Any assistance provided would be greatly appreciated.

Thank you in advance. Please feel free to reach out if you have any questions or require further information.

When it comes to testing Node code, I rely on mocha chai and Sinon for their effectiveness. However, I haven't had the chance to use them with Angular yet.

For Angular projects, the standard setup usually includes Karma, Jasmine for unit testing, and Protractor for E2E testing.

After reviewing your controller code, it appears that there is an overload of logic within the controller itself. Consider moving some of this logic into a separate service.

When testing $http functions, make sure to utilize ng-mock's $httpBackend to ensure proper functionality.

Additionally, implementing the Angular Controller As syntax in your code can help improve readability and organization.
