我有一个ParseService，我想嘲笑的顺序测试所有的控制器，使用它，我一直在阅读关于茉莉花间谍，但它仍然不清楚我。任何人都可以给我一个例子，如何模拟自定义服务，并在控制器测试中使用它？
现在我有一个控制器使用服务插入一本书：
BookCrossingApp.controller('AddBookCtrl',function ($scope,DataService,$location) {
$scope.registerNewBook = function (book) {
DataService.registerBook(book,function (isResult,result) {
$scope.$apply(function () {
$scope.registerResult = isResult ? "Success" : result;
});
if (isResult) {
//$scope.registerResult = "Success";
$location.path('/main');
}
else {
$scope.registerResult = "Fail!";
//$location.path('/');
}
});
};
});
服务是这样的：
angular.module('DataServices',[])
/**
* Parse Service
* Use Parse.com as a back-end for the application.
*/
.factory('ParseService',function () {
var ParseService = {
name: "Parse",registerBook: function registerBook(bookk,callback) {
var book = new Book();
book.set("title",bookk.title);
book.set("description",bookk.Description);
book.set("registrationId",bookk.RegistrationId);
var newAcl = new Parse.ACL(Parse.User.current());
newAcl.setPublicReadAccess(true);
book.setACL(newAcl);
book.save(null,{
success: function (book) {
// The object was saved successfully.
callback(true,null);
},error: function (book,error) {
// The save Failed.
// error is a Parse.Error with an error code and description.
callback(false,error);
}
});
}
};
return ParseService;
});
到目前为止我的测试看起来像这样：
describe('Controller: AddBookCtrl',function() {
// // load the controller's module
beforeEach(module('BookCrossingApp'));
var AddBookCtrl,scope,book;
// Initialize the controller and a mock scope
beforeEach(inject(function($controller,$rootScope) {
scope = $rootScope;
book = {title: "fooTitle13"};
AddBookCtrl = $controller('AddBookCtrl',{
$scope: scope
});
}));
it('should call Parse Service method',function () {
//We need to get the injector from angular
var $injector = angular.injector([ 'DataServices' ]);
//We get the service from the injector that we have called
var mockService = $injector.get( 'ParseService' );
mockService.registerBook = jasmine.createSpy("registerBook");
scope.registerNewBook(book);
//With this call we SPY the method registerBook of our mockservice
//we have to make sure that the register book have been called after the call of our Controller
expect(mockService.registerBook).toHaveBeenCalled();
});
it('Dummy test',function () {
expect(true).toBe(true);
});
});
现在测试失败：
Expected spy registerBook to have been called. Error: Expected spy registerBook to have been called.
我做错了什么？
我做错了没有注入Mocked服务到beforeEach的控制器：
原文链接：https://www.f2er.com/angularjs/146018.htmldescribe('Controller: AddBookCtrl',function() {
var scope;
var ParseServiceMock;
var AddBookCtrl;
// load the controller's module
beforeEach(module('BookCrossingApp'));
// define the mock Parse service
beforeEach(function() {
ParseServiceMock = {
registerBook: function(book) {},getBookRegistrationId: function() {}
};
});
// inject the required services and instantiate the controller
beforeEach(inject(function($rootScope,$controller) {
scope = $rootScope.$new();
AddBookCtrl = $controller('AddBookCtrl',{
$scope: scope,DataService: ParseServiceMock
});
}));
it('should call registerBook Parse Service method',function () {
var book = {title: "fooTitle"}
spyOn(ParseServiceMock,'registerBook').andCallThrough();
//spyOn(ParseServiceMock,'getBookRegistrationId').andCallThrough();
scope.registerNewBook(book);
expect(ParseServiceMock.registerBook).toHaveBeenCalled();
//expect(ParseServiceMock.getBookRegistrationId).toHaveBeenCalled();
});
});
