Question

我正在尝试设置一个Karma测试套件，我的代码的基线是mean stack。我正在尝试编写一些测试（特别是登录），它看起来像：

(function() {
  describe('LoginController', function() {
    beforeEach(module('mean'));

    var scope, rootScope, LoginController, $httpBackend, $location;

    beforeEach(inject(function($controller, $rootScope, _$httpBackend_, _$location_) {
      scope = $rootScope.$new();
      rootScope = $rootScope.$new();

      LoginController = $controller('LoginController', {
        $scope: scope,
        $rootScope: rootScope
      });

      $httpBackend = _$httpBackend_;

      $location = _$location_;
    }));

    it('should show danger when wrong credentials are used', function() {
      scope.credentials = {
        email: 'test@email.com',
        password: 'password'
      }

      $httpBackend.expectPOST('/api/v1/user/auth').respond({
        status: 'error',
        error: 'Invalid User'
      });


      scope.authenticate();
      $httpBackend.flush();

      expect(scope.status_object).toEqualData({text: 'Invalid User', class: 'danger', show: true});
    });
  });
})();

在我的public/js/config.js中，我有一些额外的逻辑可以加载其他一些http请求。在我的karma控制台中，我得到：

WARN [web-server]: 404: /lang/en-US.json
WARN [web-server]: 404: /api/v1/user/session
PhantomJS 1.9.7 (Mac OS X) LoginController should show danger when wrong credentials are used FAILED
    Error: Unexpected request: GET /lang/en-US.json
    Expected POST /api/v1/user/auth

如何设置我的测试以获得那些？

karma.conf.js

module.exports = function(config) {
    config.set({

        // coverage
        preprocessors: {
            // source files, that you wanna generate coverage for

        // Continuous Integration mode
        // if true, it capture browsers, run tests and exit
        singleRun: true
    });
};

我的public/js/config.js有：

.run(['$rootScope', '$location', 'UserService', 'CompanyService', function($rootScope, $location, UserService, CompanyService) {
  $rootScope.globals = {};

  $rootScope.$on('login', function(event, data) {
    $rootScope.api_key = data.api_key;
    CompanyService.get(data.user.company_id);
  });

  UserService.checkAuth().then(function(response) {
    if(response.data.user) {
      // Logged in user
      $rootScope.$broadcast('login', response.data);

      $rootScope.$watch(function () {return $location.path()}, function (newLocation) {
        $rootScope.globals.accessPath = newLocation.split('/')[1];

        if(newLocation !== '/login') {
          if(UserService.getAccess() !== $rootScope.globals.accessPath) {
            alert('Invalid access');
            UserService.logout();
          }
        } else {
          $location.path(UserService.getAccess());
        }
      });
    } else {
      UserService.logout();
    }
  });
}]);

您可以将对 UserService.checkAuth（）的调用解压缩到另一个模块，例如'init-module'并在该模块的运行块中调用。然后让你的模块依赖于init-module，以便Angular加载它并执行它的运行块：

angular.module('init-module', []).run(function() {
     // call UserService.checkAuth() here
})
angular.module('my-production-module', ['init-module']);

进行单元测试时，您可以通过执行以下命令在规范运行之前模拟整个init-module：

angular.module('init-module', function () {});

来自AngularJS module documentation - “......将您的应用程序分解为多个模块...... ...以及一个依赖于上述模块的应用程序级模块，它具有初始化代码...... 这种分解的原因是在测试中，通常需要忽略初始化代码，这往往很难测试。通过将其放入单独的模块中，可以在测试中轻松忽略它。只需加载与测试“

相关的模块，测试也可以更集中
