I've read a couple of threads on this but can't figure out a solution to my problem. In my controller I have a function:
this.dName = function() {
var url = $location.absUrl();
var matches = url.match(/\/dName\/(.*)$/);
return matches[1];
};
This causes my tests to fail as there is no absolute url to grab. How would I go about mocking $location.absUrl so that my tests can pass?
For example you could spy on the $location service, in jasmine that would be:
describe('MyController', function(){
beforeEach(module('myApp'));
var MyController, scope, $location;
beforeEach(inject(function($injector) {
var $controller = $injector.get('$controller');
var $rootScope = $injector.get('$rootScope');
$location = $injector.get('$location');
scope = $rootScope.$new();
MyController = $controller('MyController', {
$scope: scope,
});
}));
it('Check dName', function () {
spyOn($location, 'absUrl').and.returnValue(["match0", "match1"]);
var match = scope.dName();
expect(match).toEqual("match1");
expect($location.absUrl).toHaveBeenCalled();
});
});

I'm using karma, angular and mocha.
The MyServices module I want to inject. It's addThing method also calls a $localStorage provider and I want to test that the $localStorage.setItem method has been implicitly called when I call MyServices.addThing(data)
Here's my code:
describe('MyServices', function() {
var $q;
var $rootScope;
var $scope;
var MyServices;
var $timeout;
var $httpBackend;
// inject modules
beforeEach(function(){
module('my.stuff');
var _LocalStorage_ = {
setItem: function(){
return 'foo';
}
};
// mock the dependencies of the module we are testing
module(function ($provide) {
$provide.value('$localStorage', _LocalStorage_); //here is where the error occurs
});
});
beforeEach(inject(function (_$q_, _$rootScope_, _$timeout_, _MyServices_, _$httpBackend_) {
$q = _$q_;
$rootScope = _$rootScope_;
$timeout = _$timeout_;
MyServices = _MyServices_;
$httpBackend = _$httpBackend_;
$scope = $rootScope.$new();
}));
it.only('should call a method and access localStorage', function(){
var spyAdd = sinon.spy(MyServices, 'addThing');
var spySetItem = sinon.spy($localStorage, 'setItem');
MyServices.addThing({ name: 'Thing' });
expect(spyAdd.callCount).to.equal(1);
expect(spySetItem.callCount).to.equal(1);
})
});
When I run it I get an error that $localStorage is undefined.
you don't have register that fake $localStorage, just use the original one and create a spy on the setItem method.
so remove this
var _LocalStorage_ = {
setItem: function(){
return 'foo';
}
};
module(function ($provide) {
$provide.value('$localStorage', _LocalStorage_); //here is where the error occurs
});
but inject it here
var $localStorage;
beforeEach(inject(function (_$q_, _$rootScope_, _$timeout_, _MyServices_, _$httpBackend_, _$localStorage_) {
$q = _$q_;
$rootScope = _$rootScope_;
$timeout = _$timeout_;
MyServices = _MyServices_;
$httpBackend = _$httpBackend_;
$scope = $rootScope.$new();
$localStorage = _$localStorage_; //here
}));
since you have already created a spy on the method, so nothing needs to be changed in the test.
Try to declare LocalStorage outside of your beforeEach. Btw, you don't need the _, you can just call it LocalStorage.
I also recommend downloading SinonJS because it has a bunch of useful methods when spying or mocking dependencies.
I'm very new to the AngularJs unit testing with Jasmine.So could you tell me how can I test below mentioned controller and countyService.getAllCountiesAsync() method using Jasmine.Thanks in advance.
Note : The controller below is having more than 50 injected services (I have shown few below).So I don't know which method is good for mock those also ?
Controller :
(function () {
appModule.controller('myController', [
'$scope', '$modalInstance', 'abp.services.app.property', 'abp.services.app.county', 'abp.services.app.propertyClass', 'abp.services.app.schoolDistrict'
function ($scope, $modalInstance, propertyService, countyService, propertyClassService, schoolDistrictService) {
vm.getAllCounties = function () {
countyService.getAllCountiesAsync().success(function (result) {
vm.counties = result.items;
});
};
vm.getAllCounties();
} ]);
})();
WebApi method :
public async Task<ListResultOutput<CountyListDto>> GetAllCountiesAsync()
{
var counties = await _countyRepository
.GetAllListAsync();
return new ListResultOutput<CountyListDto>(counties.OrderBy(o => o.Name).MapTo<List<CountyListDto>>());
}
You should write test cases for service and controller.
For services 'Daan van Hulst' has already given answer and for controller see below code:
describe('service tests', function () {
var $compile,$controller,myController, $rootScope, propertyService, countyService, propertyClassService, schoolDistrictService;
//All module dependencies
beforeEach(module('your-app-name'));
//inject required services and _$controller_ to create controller
beforeEach(inject(function(_$compile_,_$controller_, _$rootScope_, _propertyService_, _countyService_, _propertyClassService_, _schoolDistrictService_) {
$compile = _$compile_;
$rootScope = _$rootScope_;
$controller = _$controller_; // This is IMP
countyService = _countyService_;
// remianig services
// Now create controller
myController = $controller('myController', {
$scope : scope,
propertyService : propertyService // all other services
});}
it('should test something', function() {
spyOn(countyService, 'getAllCountiesAsync').and.callFake(function () {
var d = q.defer();
d.resolve({ items: [{data:'somedata'}] });
return d.promise;
});
myController.getAllCounties();
expect(myController.counties).not.toBe(null);
});
Update
I might have made mistakes, but this is the idea:
describe('service tests', function () {
var $compile, $rootScope, scope, vm, propertyService, countyService, propertyClassService, schoolDistrictService;
beforeEach(module('your-app-name'));
beforeEach(inject(function(_$compile_, _$rootScope_, $controller, _propertyService_, _countyService_, _propertyClassService_, _schoolDistrictService_) {
$compile = _$compile_;
$rootScope = _$rootScope_;
scope = $rootScope.$new();
propertyService = _propertyService_;
countyService = _countyService_;
propertyClassService = _propertyClassService_;
schoolDistrictService = _schoolDistrictService_;
vm = $controller('myController', {'$scope': scope})
spyOn(countyService, "getAllCountiesAsync").and.callFake(function() {
var deferred = $q.defer();
deferred.resolve({data: [{id:0}]});
return deferred.promise;
});
}));
it('can do remote call', inject(function() {
//Arrange
result = [{id:0}];
// Act
vm.getAllCounties();
// Assert
expect(vm.counties).toBe(result); //assert to whatever is resolved in the spyOn function
});
});
}
I assume that you create Angular services for all your services and that you app is working. Then, you can inject them in your tests:
describe('service tests', function () {
var $compile, $rootScope, propertyService, countyService, propertyClassService, schoolDistrictService;
beforeEach(module('your-app-name'));
beforeEach(inject(function(_$compile_, _$rootScope_, _propertyService_, _countyService_, _propertyClassService_, _schoolDistrictService_) {
$compile = _$compile_;
$rootScope = _$rootScope_;
propertyService = _propertyService_;
countyService = _countyService_;
propertyClassService = _propertyClassService_;
schoolDistrictService = _schoolDistrictService_;
}));
it('should test something', function() {
expect(propertyService).toBeDefined();
expect(countyService).toBeDefined();
expect(propertyClassService).toBeDefined();
expect(schoolDistrictService).toBeDefined();
});
});
Update
I accidentally posted my solution in the answer above, so corrected it now. You can create your controller with $controller and pass in a scope object. You can also pass in any other dependencies. Then create a spy on the service, and once it gets called, call a different function which resolves a promise with mock data:
describe('service tests', function () {
var $compile, $rootScope, scope, vm, propertyService, countyService, propertyClassService, schoolDistrictService;
beforeEach(module('your-app-name'));
beforeEach(inject(function(_$compile_, _$rootScope_, $controller, _propertyService_, _countyService_, _propertyClassService_, _schoolDistrictService_) {
$compile = _$compile_;
$rootScope = _$rootScope_;
scope = $rootScope.$new();
propertyService = _propertyService_;
countyService = _countyService_;
propertyClassService = _propertyClassService_;
schoolDistrictService = _schoolDistrictService_;
// Create the controller, and pass in the scope with possible variables that you want to mock.
vm = $controller('myController', {'$scope': scope})
//Create a spy on your getAllCountiesAsync function and make it return a mock promise with mock data.
spyOn(countyService, "getAllCountiesAsync").and.callFake(function() {
var deferred = $q.defer();
deferred.resolve({data: [{id:0}]});
return deferred.promise;
});
}));
it('can do remote call', inject(function() {
//Arrange
result = [{id:0}];
// Act
vm.getAllCounties();
//I think that you also have to do this, but I am not a 100% sure.
scope.$apply();
// Assert
expect(vm.counties).toBe(result); //assert to whatever is resolved in the spyOn function
});
});
}
I am following this video tutorial and its source is here.
I am trying to apply this test
Here is my test
describe("InStudentController", function () {
beforeEach(module("eucngts"));
var inStudentsController;
var MyInStudentsService;
var $scope;
var $q;
var deferred;
beforeEach(function () {
MyInStudentsService =
{
getInStudents: function () {
deferred = $q.defer();
return deferred.promise;
}
};
});
beforeEach(inject(function ($controller, $rootScope, _$q_) {
$q = _$q_;
$scope = $rootScope.$new();
inStudentsController = $controller('InStudentsController', {
service: MyInStudentsService
});
}));
it("should request list of inStudents", function () {
spyOn(MyInStudentsService, "getInStudents").and.callThrough();
inStudentsController.getPage(); // <-- HERE
//deferred.resolve();
$scope.$root.$digest();
expect(MyInStudentsService.getInStudents).toHaveBeenCalled();
});
});
Here is relevant controller code:
InStudentsController.prototype.getPage = function (criteria) {
var self = this;
self.showGrid = true;
self.service.getInStudents();
};
When I call getPage() on test it calls real service method instead of defined in test.
What am I doing wrong?
EDIT
I don't use scope in my controller here is generated code(I use typescript):
function InStudentsController (service) {
var self = this;
self.service = service;
}
InStudentsController.$inject = ['InStudentsService'];
angular.module("eucngts").controller("InStudentsController", InStudentsController);
According to your latest update it is clear that the name of dependency is used wrong in the test. It must be InStudentsService instead of service. When using $inject property of controller constructor only that name matters, not the formal parameter name in function. That makes minification possible
inStudentsController = $controller('InStudentsController', {
InStudentsService: MyInStudentsService
});
Right now you're not injecting a scope into the controller. I think this:
$scope = $rootScope.$new();
inStudentsController = $controller('InStudentsController', {
service: MyInStudentsService
});
Should be this:
$scope = $rootScope.$new();
$scope.service = MyInStudentsService
inStudentsController = $controller('InStudentsController', {
$scope: $scope
});
But it seems odd passing the service in on the scope. Instead, you should be declaring the controller something like this:
angular.module('myApp')
.controller('InStudentsController', function ($scope, InStudentsService) {
...
});
And then the service would be injected like so:
$scope = $rootScope.$new();
inStudentsController = $controller('InStudentsController', {
$scope: $scope,
InStudentsService: MyInStudentsService
});
My controller is:
angularMoonApp.controller('SourceController', ['$scope', '$rootScope', '$routeParams', 'fileService', function ($scope, $rootScope, $routeParams, fileService) {
$scope.init = function() {
$rootScope.currentItem = 'source';
fileService.getContents($routeParams.path).then(function(response) {
$scope.contents = response.data;
$scope.fileContents = null;
if(_.isArray($scope.contents)) {
// We have a listing of files
$scope.breadcrumbPath = response.data[0].path.split('/');
} else {
// We have one file
$scope.breadcrumbPath = response.data.path.split('/');
$scope.breadcrumbPath.push('');
$scope.fileContents = atob(response.data.content);
fileService.getCommits(response.data.path).then(function(response) {
$scope.commits = response.data;
});
}
});
}
$scope.init();
}]);
My test is pretty simple:
(function() {
describe('SourceController', function() {
var $scope, $rootScope, $httpBackend, createController;
beforeEach(module('angularMoon'));
beforeEach(inject(function($injector) {
$httpBackend = $injector.get('$httpBackend');
$rootScope = $injector.get('$rootScope');
$scope = $rootScope.$new();
var $controller = $injector.get('$controller');
createController = function() {
return $controller('SourceController', {
'$scope': $scope
});
};
}));
it("should set the current menu item to 'source'", function() {
createController();
$scope.init();
expect($rootScope.currentItem).toBe('source');
});
it("should get the contents of the root folder", function() {
createController();
$scope.init();
// NOT SURE WHAT TO DO HERE!
});
});
})();
I want to test that the fileService had it's getContents function called and mock a response so that I can test the two scenarios (if is array and if isn't`)
I would recommend using Jasmine spies for this.
Here is an example that might help. I usually put the spyOn call in the beforeEach.
var mockedResponse = {};
spyOn(fileService, "getContents").andReturn(mockedResponse);
In the 'it' part:
expect(fileService.getContents).toHaveBeenCalled();
To get the response, just call the method in your controller that calls the fileService method. You may need to manually run a digest cycle too. Snippet from one of my tests:
var testOrgs = [];
beforeEach(inject(function(coresvc) {
deferred.resolve(testOrgs);
spyOn(coresvc, 'getOrganizations').andReturn(deferred.promise);
scope.getAllOrganizations();
scope.$digest();
}));
it("getOrganizations() test the spy call", inject(function(coresvc) {
expect(coresvc.getOrganizations).toHaveBeenCalled();
}));
it("$scope.organizations should be populated", function() {
expect(scope.allOrganizations).toEqual(testOrgs);
expect(scope.allOrganizations.length).toEqual(0);
});
deferred in this case is a promise created with $q.defer();
You can create a spy and verify only that fileService.getContents is called, or either verify extra calls (like promise resolution) by making the spy call through. Probably you should also interact with httpBackend since you may need to flush the http service (even though you use the mock service).
(function() {
describe('SourceController', function() {
var $scope, $rootScope, $httpBackend, createController, fileService;
beforeEach(module('angularMoon'));
beforeEach(inject(function($injector) {
$httpBackend = $injector.get('$httpBackend');
$rootScope = $injector.get('$rootScope');
$scope = $rootScope.$new();
// See here
fileService = $injector.get('fileService');
spyOn(fileService, 'getContents').andCallThrough();
var $controller = $injector.get('$controller');
createController = function() {
return $controller('SourceController', {
'$scope': $scope
'fileService': fileService
});
};
}));
it("should get the contents of the root folder", function() {
createController();
$scope.init();
expect(fileService.getContents).toHaveBeenCalled();
});
});
})();
You can also add expectations to what happens inside the callback but you should issue a httpBackend.flush() before.
We have few methods in Angular Controller, which are not on the scope variable.
Does anyone know, how we can execute or call those methods inside Jasmine tests?
Here is the main code.
var testController = TestModule.controller('testController', function($scope, testService)
{
function handleSuccessOfAPI(data) {
if (angular.isObject(data))
{
$scope.testData = data;
}
}
function handleFailureOfAPI(status) {
console.log("handleFailureOfAPIexecuted :: status :: "+status);
}
// this is controller initialize function.
function init() {
$scope.testData = null;
// partial URL
$scope.strPartialTestURL = "partials/testView.html;
// send test http request
testService.getTestDataFromServer('testURI', handleSuccessOfAPI, handleFailureOfAPI);
}
init();
}
Now in my jasmine test, we are passing "handleSuccessOfAPI" and "handleFailureOfAPI" method, but these are undefined.
Here is jasmine test code.
describe('Unit Test :: Test Controller', function() {
var scope;
var testController;
var httpBackend;
var testService;
beforeEach( function() {
module('test-angular-angular');
inject(function($httpBackend, _testService_, $controller, $rootScope) {
httpBackend = $httpBackend;
testService= _testService_;
scope = $rootScope.$new();
testController= $controller('testController', { $scope: scope, testService: testService});
});
});
afterEach(function() {
httpBackend.verifyNoOutstandingExpectation();
httpBackend.verifyNoOutstandingRequest();
});
it('Test controller data', function (){
var URL = 'test server url';
// set up some data for the http call to return and test later.
var returnData = { excited: true };
// create expectation
httpBackend.expectGET(URL ).respond(200, returnData);
// make the call.
testService.getTestDataFromServer(URL , handleSuccessOfAPI, handleFailureOfAPI);
$scope.$apply(function() {
$scope.runTest();
});
// flush the backend to "execute" the request to do the expectedGET assertion.
httpBackend.flush();
// check the result.
// (after Angular 1.2.5: be sure to use `toEqual` and not `toBe`
// as the object will be a copy and not the same instance.)
expect(scope.testData ).not.toBe(null);
});
});
I know this is an old case but here is the solution I am using.
Use the 'this' of your controller
.controller('newController',['$scope',function($scope){
var $this = this;
$this.testMe = function(val){
$scope.myVal = parseInt(val)+1;
}
}]);
Here is the test:
describe('newDir', function(){
var svc,
$rootScope,
$scope,
$controller,
ctrl;
beforeEach(function () {
module('myMod');
});
beforeEach(function () {
inject(function ( _$controller_,_$rootScope_) {
$controller = _$controller_;
$rootScope = _$rootScope_;
$compile = _$compile_;
$scope = $rootScope.$new();
ctrl = $controller('newController', {'$rootScope': $rootScope, '$scope': $scope });
});
});
it('testMe inc number', function() {
ctrl.testMe(10)
expect($scope.myVal).toEqual(11);
});
});
Full Code Example
As is you won't have access to those functions. When you define a named JS function it's the same as if you were to say
var handleSuccessOfAPI = function(){};
In which case it would be pretty clear to see that the var is only in the scope within the block and there is no external reference to it from the wrapping controller.
Any function which could be called discretely (and therefore tested) will be available on the $scope of the controller.
