Let's say I have this service. PhotoService.getPhotos returns an $http
promise:
angular.module('app').factory('PhotoService', function($http) {
return {
getPhotos: function() {
return $http({
method: 'GET',
url: '/photos',
params: {
showAuthor: true,
showSizes: false
}
});
}
};
});
I want to write a unit test that checks for the following conditions:
1. when PhotoService.getPhotos() is called, a 'GET' request to
'/photos.json' is made.
2. when PhotoService.getPhotos() is called, two params are passed called
showAuthor and showSizes.
describe('photo-service', function() {
var photoService, $httpBackend;
beforeEach(module('app'));
beforeEach(function(PhotoService, _$httpBackend_) {
photoService = PhotoService;
$httpBackend = _$httpBackend_;
$httpBackend.whenGET('/photos?showAuthor=true&showSizes=false').respond(200,
'great');
});
it('should make a GET request when PhotoService.getPhotos is called',
function() {
$httpBackend.expectGET('/photos?showAuthor=true&showSizes=false');
$httpBackend.flush();
});
it('should have showAuthor and showSies as query params', function() {
// no idea how to get the URL actually called in the real service here?
});
afterEach(function() {
$httpBackend.verifyNoOutstandingExpectation();
$httpBackend.verifyNoOutstandingRequest();
});
})
The first test passes just fine and if I change 'GET' to 'POST' in the
service, the test appropriately fails. Here are my questions:
*1. The first test passes yet I didn't have to call
PhotoServices.getPhotos() in my test case? I'm used to mocking out $q
promises where I callThrough() using a Jasmine spy on a method.*
*2. How do I test which query params are being sent in a request?*
