我有一个在AngularJS控制器中定义的方法,在初始化时调用.我想用Jasmine测试它(“jasmine-core”：“^ 2.3.4”,“karma”：“^ 0.12.37”).我在互联网和StackOverflow问题上遵循一些教程,但我找不到正确的答案.请看一下这段代码：
Controller usersAddUserController：
(function () {
'use strict';
angular.module('app.users.addUser')
.controller('usersAddUserController',['$scope','usersAddUserService',function ($scope,usersAddUserService) {
usersAddUserService.getCountryPhoneCodes().then(function (phoneCodes) {
$scope.phoneCodes = phoneCodes;
});
}]);
}());
茉莉花测试：
(function () {
'use strict';
describe('usersAddUserControllerUnitTest',function () {
var scope,deferred,objectUnderTest,mockedAddUserService;
beforeEach(module('app'));
beforeEach(inject(function ($rootScope,$q,$controller) {
scope = $rootScope.$new();
function emptyPromise() {
deferred = $q.defer();
return deferred.promise;
}
mockedAddUserService = {
getCountryPhoneCodes: emptyPromise
};
objectUnderTest = $controller('usersAddUserController',{
$scope: scope,usersAddUserService: mockedAddUserService
});
}));
it('should call getCountryPhoneCodes method on init',function () {
//when
spyOn(mockedAddUserService,'getCountryPhoneCodes').and.callThrough();
deferred.resolve();
scope.$root.$digest();
//then
expect(mockedAddUserService.getCountryPhoneCodes).toHaveBeenCalled();
});
});
}());
运行测试后,错误消息是：
PhantomJS 1.9.8 (Windows 7 0.0.0) usersAddUserControllerUnitTest should call getCountryPhoneCodes method on init Failed
06002
我显然遗漏了一些东西,但我无法弄清楚它是什么.任何帮助将不胜感激.
解决方法
在将模型传递到实例化控制器后,您正在监视模拟.
试试这个：
describe('usersAddUserControllerUnitTest',function () {
var scope,mockedAddUserService,$controller;
beforeEach(module('app'));
beforeEach(inject(function ($rootScope,_$controller_) {
scope = $rootScope.$new();
function emptyPromise() {
deferred = $q.defer();
return deferred.promise;
}
mockedAddUserService = {
getCountryPhoneCodes: emptyPromise
};
$controller = _$controller_;
}));
function makeController() {
objectUnderTest = $controller('usersAddUserController',{
$scope: scope,usersAddUserService: mockedAddUserService
});
}
it('should call getCountryPhoneCodes method on init',function () {
//when
spyOn(mockedAddUserService,'getCountryPhoneCodes').and.callThrough();
makeController();
deferred.resolve();
scope.$root.$digest();
//then
expect(mockedAddUserService.getCountryPhoneCodes).toHaveBeenCalled();
});
});
