[英]JavaScript - AngularJS promise not returning anything
我正在嘗試在Jasmine
的單元測試中返回一個簡單的HTTP帖子,但它似乎不起作用。 該應用程序可以在網絡上正常運行。 我已經測試了幾個隔離的功能。 但這是行不通的。
describe('Service: Auth',function(){
beforeEach(function () {
module('ui.router');
module('main');
module('users');
});
var AuthFactory, httpBackend;
beforeEach(inject(function($httpBackend, _AuthFactory_) {
httpBackend = $httpBackend;
AuthFactory = _AuthFactory_;
}));
it('should return POST', function() {
AuthFactory.signIn({inputUser: {username: "admin"}, passInput: {password: "adminpass"}}).then(
function(result) {
console.log('======== SUCCESS ========');
console.log(result);
},
function(err) {
console.log('======== ERROR ========');
console.log(err);
},
function(progress) {
console.log('======== PROGRESS ========');
console.log(progress);
}
);
console.log('HTTP call finished.');
expect(1).toBe(1);
});
});
這是工廠 :
angular.module('users').factory('AuthFactory', ['$http', function($http) {
var AuthFactory = {};
AuthFactory.signIn = function(data) {
return $http.post('http://127.0.0.1:3000/api/AuthFactoryServ/signIn', data);
};
AuthFactory.signOut = function(data) {
return $http.post('http://127.0.0.1:3000/api/AuthFactoryServ/signOut', data);
};
return AuthFactory;
}]);
這是我得到的:
PhantomJS 1.9.8 (Windows 7 0.0.0): Executed 0 of 1 SUCCESS (0 s
LOG: Object{$$state: Object{status: 0}, success: function (fn)
{ ... }, error: function (fn) { ... }}
PhantomJS 1.9.8 (Windows 7 0.0.0): Executed 0 of 1 SUCCESS (0 s
LOG: 'HTTP call finished.'
PhantomJS 1.9.8 (Windows 7 0.0.0): Executed 0 of 1 SUCCESS (0 s
PhantomJS 1.9.8 (Windows 7 0.0.0): Executed 1 of 1 SUCCESS (0 s
PhantomJS 1.9.8 (Windows 7 0.0.0): Executed 1 of 1 SUCCESS (0 secs / 0.022 secs)
我已經通過Postman測試了HTTP調用,它成功返回了數據。 所以...我在做什么錯?
謝謝。
AuthFactory.signIn
是異步的,並返回一個AuthFactory.signIn
您的測試函數在AuthFactory.signIn
被解決之前AuthFactory.signIn
完成。
您需要告訴Jasmine它應該等待異步測試完成 :
it('should return POST', function(done) {
var result = AuthFactory.signIn({inputUser: {username: "admin"}, passInput: {password: "adminpass"}}).then(
function(result) {
console.log('======== SUCCESS ========');
console.log(result);
},
function(err) {
console.log('======== ERROR ========');
console.log(err);
},
function(progress) {
console.log('======== PROGRESS ========');
console.log(progress);
}
);
result.then(function(){
console.log('HTTP call finished.');
expect(1).toBe(1);
}).finally(done); //here we hook Jasmine callback to promise chain
});
