预期的间谍会被称为[＆＃39; stateName＆＃39; ]但它从未被调用过？

Question

这很好用： spyOn($state, 'go');

但是当我执行下面的行时，它不起作用并发出此错误：

  

＆＃39;期待的间谍去了[＆＃39; stateName＆＃39; ]但确实如此   从未打过电话＆＃39;

expect($state.go).toHaveBeenCalledWith('stateName'); 
describe('Home Controller Test Suite', function() {

var HomeCtrl,$rootScope, $controller, $scope, $http, $state,factory;
var baseURL = "http://localhost:8000/";
beforeEach(module("ui.router"));
beforeEach(module("rbControllers"));
beforeEach(module("ui.bootstrap"));
beforeEach(module("toggle-switch"));
beforeEach(module("ngDraggable"));
beforeEach(module("angular-loading-bar"));
beforeEach(module("ngAnimate"));
beforeEach(module("kendo.directives"));
beforeEach(module("rbApp"));
beforeEach(inject(function(_$rootScope_ ,_$controller_,_$httpBackend_, _$state_){
    $rootScope = _$rootScope_;
    $scope = $rootScope.$new();
    $controller = _$controller_;
    httpBackend = _$httpBackend_;
    $state = _$state_;
    HomeCtrl = $controller('HomeCtrl', {'$scope': $scope, '$state': $state, 'baseURL' : baseURL, 'roobrickUiService': factory});
}));

it("Test: HomeCtrl exists or not", function() {
    expect(HomeCtrl).toBeDefined();
});

 it("Test:xxx run", function() {
    spyOn($state, 'go');
    expect($state.go).toHaveBeenCalledWith('stateName');
 });
});
