Question

我需要使用业力单元测试来测试我的登录过程，但是在执行测试时我遇到了错误。

我的登录控制器代码：

      $scope.signin = function (valid) {
        if (valid) {
            $http.post('/auth/signin', $scope.credentials).success(function (response) {
                console.log(response)
                // If successful we assign the response to the global user model
                $scope.authentication.user = response.user;

                localStorage.setItem('token',response.token.logintoken);
                // And redirect to the index page
                $scope.$dismiss();

            }).error(function (response) {
                $scope.error = response.message;
            });
        } else {
            $scope.userSigninrequredErr = true;
        }
    };

Karma测试代码：

(function () {
// Authentication controller Spec
describe('AuthenticationController', function () {
    // Initialize global variables
    var AuthenticationController,
            scope,
            $httpBackend,
            $stateParams,
            $cookieStore,
            notify,
            $location,
            modal;

    beforeEach(function () {
        jasmine.addMatchers({
            toEqualData: function (util, customEqualityTesters) {
                return {
                    compare: function (actual, expected) {
                        return {
                            pass: angular.equals(actual, expected)
                        };
                    }
                };
            }
        });
    });

    // Load the main application module
    beforeEach(module(ApplicationConfiguration.applicationModuleName));

    // The injector ignores leading and trailing underscores here (i.e. _$httpBackend_).
    // This allows us to inject a service but then attach it to a variable
    // with the same name as the service.
    beforeEach(inject(function ($controller, $rootScope, _$location_, _$stateParams_, _$httpBackend_, _$cookieStore_, _notify_) {
        // Set a new global scope
        scope = $rootScope.$new();

        // Point global variables to injected services
        $stateParams = _$stateParams_;
        $httpBackend = _$httpBackend_;
        $cookieStore = _$cookieStore_;
        notify = _notify_;
        $location = _$location_;
        modal = jasmine.createSpyObj('modal', ['show', 'hide']);
        // Initialize the Authentication controller
        AuthenticationController = $controller('AuthenticationController', {
            $scope: scope
        });
    }));



    it('$scope.signin() should login with a correct user and password', function () {
        // Test expected GET request  {user: 'Fred', token: {logintoken: 'Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9'}}
        scope.credentials.user = 'jenson';
        scope.credentials.token = {logintoken: 'Bearer eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9'};
        $httpBackend.when('POST', '/auth/signin').respond(200, scope.credentials);

        scope.signin(true);
        $httpBackend.when('GET', /\.html$/).respond('');
        $httpBackend.flush();

        // Test scope value
        expect(scope.credentials.user).toEqual('jenson');
        expect($location.url()).toEqual('/dashboard');
    });

}

我在执行karma测试后得到了正确的响应，但在devtools控制台中显示以下错误。

TypeError：＆＃39; undefined＆＃39;不是一个函数（评估＆＃39; $ scope。$ dismiss（）＆＃39;）

感谢任何帮助。感谢。

所以问题在于＆＃34;真实＆＃34;代码，模态服务正在调用控制器并为您创建一个新的范围，在其上填充$dismiss()方法，但在单元测试中，您手动调用控制器（使用$controller服务），意思是没有$scope.$dismiss()函数，因此错误。

相反，你需要做你在真实代码中做的事情，并使用模态服务来实例化你的控制器或至少，模仿模态服务的作用，并在你的新范围上添加一些存根函数，包括$dismiss()。

TypeError：＆＃39; undefined＆＃39;不是一个函数（评估＆$ 39;范围。$ dismiss（）＆＃39;）
