使用Jasmine对$ modal进行单元测试

Question

我有一个带控制器的Angular应用程序,它Angular-Strap在函数调用期间显示模态窗口.它在Chrome中正常运行,但我无法进行有效的单元测试.

App模块和FooController:

var app = angular.module("app", ["mgcrea.ngStrap"]);

app.controller("FooController", function($scope, $modal) {
    var fooModal = $modal({
        title: 'Foo',
        content:'Bar',
        show: false,
        html: true,
        backdrop: 'static',
        placement: 'center'});

    angular.extend($scope, {
        makeItFoo: function() {
            fooModal.show();
        }
    });
});

控制器规格:

describe('FooController', function () {
    var scope, controller, modal;

    beforeEach(module('app', function ($provide) {
        // Stub out $modal service
        $provide.value('$modal', function () {
            return {
                hide: function () { },
                show: function () { }
            };
        });
    }));

    beforeEach(inject(function ($rootScope, $controller, $injector) {
        //set up a new scope and the controller for the test
        scope = $rootScope.$new();
        controller = $controller('FooController', {$scope: scope});
        modal = $injector.get('$modal');
    }));

    it('should show the modal', function () {
        var modalSpy = spyOn(modal(), 'show');

        scope.makeItFoo();

        expect(modalSpy).toHaveBeenCalled();
    });
});

这也是一个小提琴.

我希望我的调用makeItFoo()显示模态,但Jasmine未通过错误测试Expected spy show to have been called.我也尝试将show模态的属性设置为true而不是show()单独调用,并且我尝试了其他变体来存储$ modal服务并将其直接注入控制器,但最终会出现相同的错误.

我正在使用AngularJS 1.2.14,Angular-Strap 2.0.0和Jasmine 1.3.1.

而不是做这些.$modal使用show和hide方法创建一个模拟对象,并设置对它们的期望.

describe('FooController', function () {
    var scope, controller, modal;

    beforeEach(module('app'));

    beforeEach(inject(function ($rootScope, $controller) {
        //set up a new scope and the controller for the test
        scope = $rootScope.$new();
        //Create spy object
        modal = jasmine.createSpyObj('modal', ['show', 'hide']);
        //provide modal as dependency to the controller.
        controller = $controller('FooController', {$scope: scope, $modal:modal});

    }));

    it('should show the modal', function () {

        scope.makeItFoo();

        expect(modal.show).toHaveBeenCalled();
    });
});
