AngularJS Jasmine test failure: Module instantiation failed

Everything was running smoothly with my angular app and tests using karma and jasmine. However, after adding a dependency in ui.bootstrap, my app continues to function as expected but now my tests won't run. Here is what I have:

app.js - added dependency in ui.bootstrap

angular.module('myApp', ['ngResource', 'ngRoute', 'ui.bootstrap']).config(function(...) {...});

service.js

angular.module('myApp').service('myService', function () {})

controller.js

angular.module('myApp').controller('MyController', function ($scope, $http, myService) {})

tests/main.js

describe('Controller: MyController', function () {
    var MyController, scope;
    // load the controller's module
    beforeEach(function(){
        module('myApp');
        inject(function ($controller, $rootScope) {
            scope = $rootScope.$new();
            MyController = $controller('MyController', {
                $scope:scope
            });
        });
    });
    it('should do something', function () {
        expect(scope.myOptions.length).toBe(5);
    });
}); 

When running my test using grunt and krama, it fails with the following error:

Error: [$injector:modulerr] Failed to instantiate module myApp due to:
Error: [$injector:modulerr] Failed to instantiate module ui.bootstrap due to:
Error: [$injector:nomod] Module 'ui.bootstrap' is not available! You either misspelled the module name or forgot

I'm puzzled as to what I've missed. The app functions properly, it's just the test that fails.

Answer №1

Within the karma.conf.js file, you will find a section containing a list of files that Karma loads before executing tests:

// list of files / patterns to load in the browser
files: [
  'bower_components/angular/angular.js',
  'bower_components/angular-mocks/angular-mocks.js',
  ...
]

Don't forget to include bootstrap-ui.js in this list as well.

Answer №2

Establish your dependencies

beforeEach(function(){
   angular.module('ui.bootstrap',[]);
});

Answer №3

After encountering the same issue, I managed to find a solution. It seems that including the module(myApp); function call within the function passed to beforeEach() does not work correctly. Instead, try separating the module call like this:

Create a separate beforeEach() for the module call:

beforeEach(module('myApp'));

Then, use another beforeEach() specifically for the function you need.
