UnknownError：JavaScript錯誤：[$ injector：unpr]未知提供程序

Question

嘗試為我的角度應用程序創建量角器測試，這是我嘗試從Jasmine腳本調用的服務：

var app =angular.module('app',[]);

app.factory('myService', function($http) {
        var myService = {
            async: function() {
                // $http returns a promise, which has a then function, which also returns a promise
                var promise = $http.get('test.json').then(function (response) {
                    // The then function here is an opportunity to modify the response
                    console.log(response);
                    // The return value gets picked up by the then in the controller.
                    return response.data;
                });
                // Return the promise to the controller
                return promise;
            }
        };
        return myService;
    });

;

我的規范是這樣定義的：

it('should call api i the site', function () {
    browser.executeAsyncScript(function(callback) {
    var callback = arguments[arguments.length - 1];
    var myService = angular.injector(['ng']).get('myService');
    myService.async().then(function (d) {
            $scope.data = d;
    });
    callback(null, true);
    });
})

當我運行腳本時，包含angular.injector（['ng']）。get（'myService'）的行會導致以下錯誤：

UnknownError: javascript error: [$injector:unpr] Unknown provider: myServiceProvider <- myService

正確的噴油嘴說明是什么？

試試這個

var injector = angular.injector(['app', 'ng']);
var myService = injector.get('myService');
