在茉莉指令控制器中返回一个承诺

Question

在我的单元测试中，我需要返回一个承诺，这样我的测试就不会失败：

describe('refugeeRegister', function () {
  var controller, scope, rootScope, window;
  beforeEach(function () {
    module('refugeeHire');
    module("templates");
    module('refugeeHire.components.refugee_register', function ($provide) {
      $provide.service("authenticationService", function () {
        this.signup = jasmine.createSpy("signup").and.returnValue();
        this.getCookie=jasmine.createSpy("getCookie");
      });
    });
  });
  beforeEach(inject(function ($rootScope, $compile) {
    el = angular.element("<refugee-register></refugee-register>");
    $compile(el)($rootScope.$new());
    $rootScope.$digest();
    rootScope = $rootScope;
    controller = el.controller("refugeeRegister");
    scope = el.isolateScope() || el.scope();
  }));
  it("should have initialized variables", function () {
    expect(scope.vm).toBeDefined();
  });
  it("should register a user", function () {
    scope.register();
    expect(rootScope.globals.loading).toBe(true);
    expect(authenticationService.signup).toHaveBeenCalled();
  });
});

它应该测试此模块（控制器内部有逻辑）：

function refugeeRegister() {
        var directive = {
          restrict: 'E',
          templateUrl: 'components/register/refugee/refugee_register.html',
          scope: {},
          controller: refugeeRegisterController,
          controllerAs: 'vm',
          bindToController: true
        };

测试中的错误如下：

TypeError: undefined is not an object (evaluating 'authenticationService.signup($scope.vm, "REFUGEE").then') in /Users/fabianlurz/refugeehire/app/components/register/refugee/refugee_register.js (line 73)
    register@/Users/fabianlurz/refugeehire/app/components/register/refugee/refugee_register.js:73:60
    /Users/fabianlurz/refugeehire/app/components/register/refugee/refugee_register-spec.js:35:19
PhantomJS 2.1.1 (Mac OS X 0.0.0): Executed 4 of 4 (1 FAILED) (0.004 secs / 0.407 secs)

那么如何在我的模拟服务（身份验证服务）中返回承诺呢？

Answer 1

对于硬编码的静态分辨率，它可能是

this.signup = jasmine.createSpy("signup").and.returnValue($q.resolve('...');

对于动态解析，应在每次调用时发出新承诺：

this.signup = jasmine.createSpy("signup").and.callFake(function () {
  return $q.resolve(...);
});
