Question

我尝试在茉莉花测试中向我的控制器注入一个工厂 Unit testing AngularJS factories that have dependencies

当我在测试中提供工厂时，我希望控制器使用提供的工厂。但是console.log仍然打印出真正的价值＆＃39;。我不明白。

var app = angular.module('mod', []);

app.factory('factoryA', [
    function () {
        return "real value";
    }
]);

app.controller('myController', ['factoryA',
    function (factoryA) {
        console.log(factoryA);
    }
]);


describe("test", function() {
    var $scope, $controller, $httpBackend;
    var app;

    beforeEach(function() {
        module(function($provide) {
            $provide.factory('factoryA', function () { return "fake value"; });
        });
        app = module("mod");

        inject(function (_$controller_, _$httpBackend_, $rootScope) {
            $httpBackend = _$httpBackend_;
            $scope = $rootScope.$new();
            $controller = _$controller_;
        });

    });

    it("works", function() {
        $controller("myController", { '$scope': $scope });
    });

});

您需要从模块$provide获取mod r，因此将模块名称作为第一个参数传递，以便它覆盖最初创建的factoryA定义。或者在设置模拟之前加载模块 - module("mod")。

   module('mod', function($provide) {
        $provide.factory('factoryA', function () { return "fake value"; });
    });

创建模拟并将其传递给控制器创建的另一种方法。

describe("test", function() {
    var $scope, $controller, $httpBackend;
    var app, factoryA;

    beforeEach(function() {
        module(mod);

        inject(function (_$controller_, _$httpBackend_, $rootScope) {
            //...Your code
            //Mock factory
            factoryA = jasmine.createSpy('factoryA');
            factoryA.and.returnValue("fake value");
        });

    });

    it("works", function() {
        //Pass the mock factory
        $controller("myController", { '$scope': $scope, factoryA:factoryA });
    });

});
