javascript - 如何使用AngularJS/Karma单元测试框架等待“whenGET”完成？

如何使用AngularJS的单元测试框架Karma / Jasmine等待whenGET()或expectGET()完成？

adminController的单元测试：

'use strict';
//SETUP
describe('spec/controllers/admin.js - adminController', function () {
        var $controller;
        var $httpBackend;
        var scope;
        var testData_admin = {
          query: {
            input: ['ADMIN']

          }

    beforeEach(module('queueManagerApp','queueManagerApp-testTemplates'));

    beforeEach(inject(function(_$controller_, _$httpBackend_) {
        $controller = _$controller_;
        scope = {};
        $httpBackend = _$httpBackend_;
        $controller('adminController',{ $scope: scope });
    }));

    // makes sure all expected requests are made by the time the test ends
    afterEach(function() {
      $httpBackend.verifyNoOutstandingExpectation();
      $httpBackend.verifyNoOutstandingRequest();
    });

//TESTS
    describe('http test ( Get user rights details -1 )', function () {
         it('admin user should have admin rights enabled (ADMIN)', function() {
             $httpBackend.whenGET('user/rights').respond(testData_admin);
             $controller('adminController',{ $scope: scope });
             var isAdmin = scope.isEnabled(testData_admin.query.input);
             $httpBackend.flush();
             expect(isAdmin).toEqual(true); //FAILING
         });
    });

});

adminController：

'use strict';

function adminController($scope, $http, $location) {

//RUN THIS SECTION FIRST
    $scope.enabledRights = [];
    $http.get('user/rights').success(function(data) {
            $scope.enabledRights = data;
    }).error(function() {
            $scope.enabledRights = [];
    });

//RUN THIS SECTION SECOND
    var isAdmin = false;
    $scope.isEnabled = function(allowedRights) {
        if($scope.enabledRights.length > 0){
            if($scope.enabledRights.indexOf(allowedRights) > -1){
                isAdmin = true;
            }else{
                isAdmin = false;
            }
         }
      return isAdmin;
    };
}

angular
  .module('queueManagerApp')
  .controller('adminController',
        ['$scope', '$http', '$location', '$filter', '$window', adminController]);

我遇到的问题是此行：

$httpBackend.whenGET('user/rights').respond(testData_admin);

在此行之后运行：

var isAdmin = scope.isEnabled(testData_admin.query.input);

因此，如何强制whenGET在作用域函数isEnabled之前运行？或如何等待whenGET完成后才能执行isEnabled？

这是我尝试过的：



尝试＃1：将then添加到whenGET

没用说那不是功能

$httpBackend.whenGET('user/rights').respond(testData_admin).then(function(){
        $controller('adminController',{ $scope: scope });
        var isAdmin = scope.isEnabled(testData_admin.query.input);
        $httpBackend.flush();
        expect(isAdmin).toEqual(true);
});

尝试＃2：使用expectGET代替whenGET

当我运行它时，我得到Unexpected GET Request 'user/rights'

$httpBackend.expectGET('user/rights').respond(testData_admin);
$controller('adminController',{ $scope: scope });
var isAdmin = scope.isEnabled(testData_admin.query.input);
$httpBackend.flush();
expect(isAdmin).toEqual(true); //FAILING

有人对我该如何解决有任何想法吗？

AngularJS's docs表示whenGET和ExpectGET没有回调函数。

先感谢您！

最佳答案

尝试这个：

describe('http test ( Get user rights details -1 )', function () {
     beforeEach(function() {
        $httpBackend.whenGET('user/rights').respond(testData_admin);
        $controller('adminController',{ $scope: scope });
     });
     it('admin user should have admin rights enabled (ADMIN)', function() {
         var isAdmin = scope.isEnabled(testData_admin.query.input);
         expect(isAdmin).toEqual(true); //FAILING
         $httpBackend.flush();
     });
});
