我有一個角度測試問題。我試圖測試$廣播是否成功解僱。我有一些奇怪的行爲,試圖使用spyOn。如果您有任何建議,請幫助我一直試圖解決這個問題好幾個小時。我的測試是這樣的:
describe('Signup controller', function() {
beforeEach(module('myApp'));
describe('SignupCtrl', function(){
var $scope, ctrl, $httpBackend, AUTH_EVENTS, $rootScope;
beforeEach(inject(function($injector, $controller,
_$httpBackend_, _apiUrl_, _AUTH_EVENTS_){
$rootScope = $injector.get('$rootScope');
$scope = $rootScope.$new();
ctrl = $controller('SignupCtrl', {$scope: $scope});
$httpBackend = _$httpBackend_;
apiUrl = _apiUrl_;
AUTH_EVENTS = _AUTH_EVENTS_;
spyOn($rootScope, "$broadcast");
}
));
afterEach(function() {
$httpBackend.verifyNoOutstandingExpectation();
$httpBackend.verifyNoOutstandingRequest();
});
it('should show error message from API', function() {
var apiMessage = 'That email already exists.';
$httpBackend.expectPOST('/users').respond(400, {
message: apiMessage
});
// call controller register function with mock empty credentials
$scope.register({});
$httpBackend.flush();
expect($rootScope.$broadcast).toHaveBeenCalledWith(AUTH_EVENTS.signupFailed);
expect($scope.errorMessage).toBe(apiMessage);
expect($scope.showErrorMessage).toBe(true);
});
});
});
而我得到的錯誤是:
TypeError: 'undefined' is not an object (evaluating '$rootScope.$broadcast('$locationChangeStart', $location.absUrl(), oldUrl).
