我正在开发一个角度应用程序。我的应用程序运行时只有很少的控制器和服务。现在我想开始对服务和控制器进行单元测试。但是不知道我做错了什么,我无法为一个单一的服务正确地运行测试。当我尝试使用业力运行测试时:
业力开始karma.conf.js
我收到以下错误:
Firefox 38.0.0 (Windows 7 0.0.0) service: MyCategoryService should send a request to MyCategoryService FAILED

我不知道哪里出错了。我试图关注this stackoverflow question但是没有线索。
任何帮助或建议都会很棒!!
这是我的应用:
'use strict';
/* App Module */
var app = angular.module('myApp', [
'ngRoute', // uri routing
'controllers', // controllers
'services', // services
'ngMock'
]);
// module controllers
var appCtrl = angular.module('controllers', []);
// module services
var appServices = angular.module('services', [ 'ngResource' ]);
这是我的服务:
'use strict';
appServices.factory('MyCategoryService', ['$resource', 'REST_RESOURCE',
function ($resource, REST_RESOURCE) {
return $resource(REST_RESOURCE.PREFERENCE, {}, {
query: {
method: 'GET',
params: {},
isArray: false
}
});
}]);
这是我的服务规范:
describe('service: MyCategoryService', function () {
var $httpBackend;
var $rootScope;
var MyCategoryService;
var REST_RESOURCE;
beforeEach(function () {
angular.mock.module('myApp');
angular.mock.inject(function ($injector) {
$httpBackend = $injector.get('$httpBackend');
$rootScope = $injector.get('$rootScope');
MyCategoryService= $injector.get('MyCategoryService');
REST_RESOURCE = $injector.get('REST_RESOURCE');
});
});
it('should send a request to MyCategoryService', function () {
//TODO
var mockdata = {
items: {
}
};
$httpBackend.expect('GET', REST_RESOURCE.PREFERENCE).respond(200, mockdata);
MyCategoryService.query(function (response) {
$rootScope.data = response.items;
});
$httpBackend.flush();
expect($rootScope.data).toEqual(mockdata);
});
});
这是我的karma.conf.js文件:
module.exports = function(config) {
config.set({
// base path that will be used to resolve all patterns (eg. files, exclude)
basePath: '',
// frameworks to use
// available frameworks: https://npmjs.org/browse/keyword/karma-adapter
frameworks: ['jasmine'],
// list of files / patterns to load in the browser
files: [
//dependencies

'bower_components/angular-mocks/angular-mocks.js',
'bower_components/angular-route/angular-route.js',
'bower_components/angular-bootstrap/ui-bootstrap.js',
'bower_components/angular-bootstrap/ui-bootstrap-tpls.js',
'bower_components/angular-cookies/angular-cookies.js',
'js/app.js',
'js/libs/*.js',
'js/directives/*.js',

],
// list of files to exclude
exclude: [

// enable / disable colors in the output (reporters and logs)
colors: true,
// level of logging
// possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG

});
};

在对某些文件进行一些更改后,我终于让我的测试运行了。我不知道具体原因是什么,但我得到了以下变化。以下是我的更改:
我删除了ngMocks依赖项。更改后,我的app.js文件如下所示。
'use strict';
/* App Module */
var app = angular.module('admintool', [ 'ngRoute', // uri routing
'controllers', // controllers
'services', // services
'angularUtils.directives.dirPagination', // pagination service
'ui.bootstrap', // angular ui bootstrap
'ui', // ui sortable
'uiSwitch', // on of switch service
'ngMessages', // for form validation
'xeditable', // for table edit
'ngCookies'
// messages
]);
// module controllers
var appCtrl = angular.module('controllers', []);
// module services
var appServices = angular.module('services', [ 'ngResource' ]);
service.js看起来像:
'use strict';
//appServices.factory('PreferenceCategory', ['$resource', 'REST_RESOURCE',
angular.module('services').factory('PreferenceCategory', ['$resource', 'REST_RESOURCE',
function ($resource, REST_RESOURCE) {
return $resource(REST_RESOURCE.PREFERENCE_CATEGORY, {}, {
query: {
method: 'GET',
params: {},
isArray: false
}
});
}]);
serviceSpec.js看起来像:
describe('Preference Category Service',
function() {
beforeEach(angular.mock.module("admintool"));
var httpBackend, pc;
beforeEach(inject(function($httpBackend, PreferenceCategory) {
httpBackend = $httpBackend;
pc = PreferenceCategory;
}));
afterEach(function() {
httpBackend.verifyNoOutstandingExpectation();
httpBackend.verifyNoOutstandingRequest();
});
it(
'Check GET Request',
function() {
httpBackend
.expectGET(
'http://jboss-pmadmin-tool-dev.ose-core.optum.com/pmadmin-tool/v1/preference_categories')
.respond({
username : 'test'
});
// call the function on our service instance
var response = pc.query();
httpBackend.flush();
expect(response.username).toEqual('test');
});
});
karma.conf.js文件,我删除了'js/libs/*'
并添加了应用中使用的单个文件。
module.exports = function(config) {
config.set({
// base path that will be used to resolve all patterns (eg. files,
// exclude)
basePath : '../admintoolui/src/main/webapp/',
// frameworks to use
// available frameworks: https://npmjs.org/browse/keyword/karma-adapter
frameworks : [ 'jasmine' ],
// list of files / patterns to load in the browser

'js/libs/pagination.js',

],
// list of files to exclude

})
