我正在开发AngularJS应用,并且在具体指令中遇到了Jasmine的SpyOn的一些问题。
该指令非常简单,只需调用服务的方法,当它解析/拒绝结果时的promise行为,即可设置一些值或其他值。
问题:当我尝试模拟SignatureService.getSignatureData
时,SpyOn无法按我预期的方式工作,并且表现得好像我是通过callThrough
调用茉莉花的getSignatureData
方法一样。
我在其他指令和服务中一直使用spyOn和嘲笑,而这些都没有问题。
与其他解决方案和用户的回答相比,最近两天我一直在尝试解决此问题,但是我找不到有效的解决方案。
这是我的代码:
AngularJS指令代码:
angular
.module('module_name')
.directive('signatureDirective', signatureDirective);
angular
.module('GenomcareApp_signature')
.controller('signatureDController', signatureDController);
function signatureDirective() {
return {
restrict: 'E',
templateUrl: 'components/signature/signature.directive.html',
controller: signatureDController,
controllerAs: 'ctrl',
bindToController: true
};
}
signatureDController.$inject = [
'$scope',
'$rootScope',
'$location',
'SignatureService'
];
function signatureDController($scope, $rootScope, $location, SignatureService) {
var controller = this;
$scope.$on('pdfFileLoadSuccessfully', function (data) {
console.log(data);
controller.loadPdfSucceed = true;
});
$scope.$on('pdfFileLoadFails', function (data) {
console.error(data);
controller.loadPdfError = true;
});
function loadDirectiveInitData() {
var queryParameters = atob($location.search().data);
controller.email = queryParameters.split(';')[0];
controller.phone = queryParameters.split(';')[1];
controller.docid = queryParameters.split(';')[2];
SignatureService.getSignatureData(controller.email, controller.phone, controller.docid)
.then(
function (data) {
console.log(data);
controller.stampTime = data.stamp_time;
controller.fileUrl = data.original_file.url;
},
function (error) {
console.error(error);
controller.error = true
})
.finally(
function () {
controller.endLoad = true;
})
}
loadDirectiveInitData();
}
茉莉花测试代码:
'use strict';
/* global loadJSONFixtures */
describe('Test :: Signature directive', function () {
beforeEach(angular.mock.module('app'));
beforeEach(module('translateNoop'));
var $q, $compile, $rootScope, controller, $scope, $httpBackend, $location, SignatureService;
beforeEach(angular.mock.inject(function (_$controller_, _$q_, _$rootScope_, _$location_, _$compile_, _$httpBackend_, _SignatureService_) {
$q = _$q_;
$compile = _$compile_;
$location = _$location_;
$scope = _$rootScope_.$new();
$httpBackend = _$httpBackend_;
SignatureService = _SignatureService_;
spyOn($location, 'search').and.returnValue({data: 'dGVzdEB0ZXN0LmNvbTsrMzQ2NjY2NjY2NjY7WG9TUFFnSkltTWF2'});
$httpBackend.whenGET('components/signature/signature.directive.html').respond(200, '');
controller = _$controller_('signatureDController', {$scope: $scope});
}));
describe('Testing directive', function () {
it('Init data should be set when promise resolves/rejects', function (done) {
// SpyOn DOES NOT MOCK THE SERVICE METHOD
spyOn(SignatureService, 'getSignatureData').and.callFake(function () {
return $q.resolve({...})
});
var element = angular.element('<signature-directive></signature-directive>');
element = $compile(element)($scope);
$scope.$digest();
done();
// ... some expect stuff
});
});
});
如果有人可以给我一些建议或解决方案,我将非常感激。
非常感谢你。
UPDATE1:我不知道为什么,但是如果不在全局
controller
中声明beforeEach
变量,Jasmine的spyOn会按我的预期模拟该方法。现在的问题是如何让控制器测试控制器值是否按预期设置。
最佳答案
好吧……我意识到问题在于,首先要创建控制器,而在模拟服务时,控制器会忽略它。
当我将服务的spyOn
粘贴到全局beforeEach
中时,这个想法是偶然产生的。
因此,我决定创建一个控制器的新实例以及相应的spyOn
,并在每个describe的beforeEach
中包含所需的结果。
有用。也许这不是最好的方法,我鼓励有答案的人张贴它。我将永远成为伟大的。
这是我的最终测试代码:
describe('Test :: Signature directive', function () {
beforeEach(angular.mock.module('app'));
beforeEach(module('translateNoop'));
var $q, $compile, $rootScope, $scope, $httpBackend, $location, SignatureService, test_fixture;
beforeEach(angular.mock.inject(function (_$q_, _$rootScope_, _$location_, _$compile_, _$httpBackend_, _SignatureService_) {
$q = _$q_;
$compile = _$compile_;
$location = _$location_;
$scope = _$rootScope_.$new();
$httpBackend = _$httpBackend_;
SignatureService = _SignatureService_;
// controller = _$controller_;
spyOn($location, 'search').and.returnValue({data: 'dGVzdEB0ZXN0LmNvbTsrMzQ2NjY2NjY2NjY7WG9TUFFnSkltTWF2'});
$httpBackend.whenGET('components/signature/signature.directive.html').respond(200, '');
}));
describe('Testing directive when service resolve promise', function () {
var controller;
beforeEach(inject(function(_$controller_) {
spyOn(SignatureService, 'getSignatureData').and.callFake(function () {
return $q.resolve({...})
});
controller = _$controller_('signatureDController', {$scope: $scope})
}));
it('Init data should be set', function () {
// spyOn($location, 'search').and.callThrough();
var element = angular.element('<signature-directive></signature-directive>');
element = $compile(element)($scope);
$scope.$digest();
// ... some expect(...).toEqual(...) stuff and more
});
});
});
感谢您的时间。
