Question

我有一个规范，测试范围内的方法是否被调用（见下文）

describe("Event Module tests", function () {

    var scope, simpleController;

    beforeEach(module('SimpleApplication'));
    beforeEach(inject(function ($rootScope, $controller) {
        scope = $rootScope.$new();
        simpleController = $controller("SimpleController", {
            $scope: scope
        });
    }));


    it("Scope function should be triggered", function () {

        spyOn(scope, "trigger");

        scope.trigger();//invoke the function on controller

        expect(scope.trigger).toHaveBeenCalled();//Passes
        expect(scope.isTriggered).toBeTruthy();//Fails

    });

});

申请代码（待测代码）：

angular
    .module("SimpleApplication", [])
    .controller("SimpleController", function ($scope) {

        $scope.message = "Hello World";

        $scope.isTriggered = false;

        $scope.trigger = function() {
            $scope.isTriggered = true;
        };
    });

Jasmine报道说“预期虚假是真的”。怎么会？因为该方法将其设置为true !!

更新

出于某种原因，SpyOn正在将我的对象变为它想要的东西。所以下面的代码很好用

it("Scope function should be triggered", function () {

            scope.trigger();//invoke the function on controller

            expect(scope.isTriggered).toBeTruthy();//Now Passes

        });

spyOn不会调用您的方法。它只是间谍。如果你想要它被调用，你必须添加一些东西：

spyOn(scope, "trigger").andCallThrough()

范围方法的Jasmine测试失败
