AngularJs廣播單元測試錯誤

Question

我對AngularJs非常陌生，並且在做單元測試。我遇到了這個問題，我寫了一個測試，它給了我這個錯誤，我意識到括號中可能會有一些錯誤，但我只是給出了一個代碼示例，以瞭解我需要如何測試它。

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

，這是爲我工作...

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

嘗試...

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