Controllers are not defined in karma unit test case

Question

i get this error when i run the test cases:

Error: [ng:areq] Argument 'testcont' is not a function, got undefined

This is my ControllerSpec.js

describe('controllers', function(){
  var scope;   
  beforeEach(angular.module('myapp.test'));   
  beforeEach(inject(function($controller, $rootScope){    
    scope = $rootScope.$new();
    $controller('testcont', {$scope:scope});
  }));

  it('should', function(){
      expect(scope.a).toBe(10)      
  })

});

This is my controllers.js

angular.module('myapp.test', [], function () {

}).controller('testcont', function($scope) {
    $scope.a = 10;
});

Answer 1

Using angular.module redefines the module myapp.test. You should use angular.mock.module (which is also set on the window object), i.e.:

beforeEach(module('myapp.test'));

Answer 2

Check the AngularJS docs on injecting a module here. Also, heere's more info on What is a Module?

When declaring your module in a unit test you dont use the anglar. prefix since you're using module from angular-mocks.js, not the same angular.module you normally use for defining controllers, services, etc.

Your unit test code line 3 should look like this: beforeEach(module('myapp.test'));
