Include dependencies in Karma test file for Angular app?

angularjs, javascript, karma-runner

Solution

In karma configuration file (karma.conf.js) you need to define all libraries.

etc.

    // list of files / patterns to load in the browser
    files: [
        'app/lib/angular/angular.js',
        'app/lib/angular-route/angular-route.js',
        'test/lib/angular-mocks.js',
        'app/app.js',
        'app/controllers/*.js',
        'app/services/*.js',
        'app/*',
        'test/spec/**/*.js'
    ],

Problem

I am trying to get started with Karma tests, adding them to an existing Angular app. This is my main app definition file: ``` angular .module('myApp', [ 'ngRoute', 'moduleAdherence' ]); ``` This is my controller file: ``` angular .module('moduleAdherence', []) .controller('AdherenceCtrl', ['$scope', function ($scope) { $scope.awesomeThings = [1,2,3,4]; }]); ``` This is my first stab at a file: ``` describe('Controller: AdherenceCtrl', function () { beforeEach(module('myApp')); var MainCtrl, scope; beforeEach(inject(function ($controller, $rootScope) { scope = $rootScope.$new(); MainCtrl = $controller('AdherenceCtrl', { $scope: scope }); })); it('should attach a list of awesomeThings to the scope', function () { expect(scope.awesomeThings.length).toBe(4); }); }); ``` When I try to run this with `grunt test`, it fails with the following error: ``` Uncaught Error: [$injector:nomod] Module 'd3' is not available! You either misspelled the module name or forgot to load it. If registering a module ensure that you specify the dependencies as the second argument. http://errors.angularjs.org/1.2.0/$injector/nomod?p0=d3 at /Users/me/Dropbox/projects/myapp/app/bower_components/angular/angular.js:1498 ``` I don't understand this, because this controller does not Use D3. I do use D3 elsewhere in the app, in a directive, but I'm not registering it with the module (I use the external D3 file). Why is Karma noticing D3? Shouldn't it be able to test this controller without D3?
