Question

我是AngularJs的新手并且正在进行单元测试。我在编写的测试中遇到了这个问题并且它给了我这个错误，我意识到括号中可能存在一些错误，但我只是给出了代码示例以了解我需要如何测试它。

Expected spy $broadcast to have been called with [ 'dataSamplesReceived', Object({ newDataSamples: Object({  }) }) ]

控制器

app.controller('fileUploadCtrl',
        function($scope, $rootScope, $log, fileUpload) {
     $scope.uploadFile = function () {
                    var file = $scope.sampleFile;
                    $rootScope.$broadcast("sampleFilesSelected", {
                        newSampleFiles: file
                    });
                        .success(function (data) {
                            $rootScope.$broadcast("dataSamplesReceived", {
                                newDataSamples: data
                            });
                        })
                        .error(function (data) {
                            alert("Upload failed");
                        });
                } // uploadFile

spec.js

    describe('test broadcast for new file opload ', function () {
    var $controller, $rootScope;

    beforeEach(function () {
        module('app');
        inject(function (_$rootScope_, _$controller_) {
            $rootScope = _$rootScope_;
            spyOn($rootScope, '$broadcast').and.callThrough();
            $controller = _$controller_;
        });
    });

    it("should select/upload new sample files", function () {
        $controller('fileUploadCtrl', {

            $scope: $rootScope.$new(),

            file: {}
        })
        expect($rootScope.$broadcast).toHaveBeenCalledWith('sampleFilesSelected', {newSampleFiles: {}})
    });


    it("should recieve data samples", function () {
        $controller('fileUploadCtrl', {

            $scope: $rootScope.$new(),

            data: {}
        })
        expect($rootScope.$broadcast).toHaveBeenCalledWith('dataSamplesReceived', {newDataSamples: {}})
    });
})

这对我有用......

spyOn(state, 'go').and.callThrough();
// blah blah 
expect(state.go).toHaveBeenCalledWith('home');

试试......

spyOn($rootScope, '$broadcast').and.callThrough();
expect($rootScope.$broadcast).toHaveBeenCalledWith('dataSamplesReceived', {newDataSamples: {}})
