Spyon angular service method returns Unexpected POST - angularjs

Question

I have a promise in a controller that I'm trying to test and I'm getting Error: Unexpected request: POST /v1/users.
I'm trying to spyOn the AuthService.changePassword which returns a promise and test whether it got called or not. Not sure why it's actually making the POST call...
controller
angular.module('example')
.controller('ChangePasswordCtrl', ['AuthService', '$state',
function(AuthService, $state) {
var vm = this;
vm.submitted = false;
vm.submit = function(valid) {
vm.submitted = true;
if (!valid) return false;
AuthService.changePassword(vm.email)
.then(function(res) {
$state.go('reset.confirmation');
}, function(err) {
vm.hasError = true;
});
};
}
]);
unit test
describe('ChangePasswordCtrl', function() {
var ctrl, scope, AuthService, $q, $state, deferred;
beforeEach(module('example'));
function _inject() {
inject(function($controller, $rootScope, _AuthService_, _$state_, _$q_) {
scope = $rootScope.$new();
$state = _$state_;
$q = _$q_;
AuthService = _AuthService_;
ctrl = $controller('ChangePasswordCtrl', {
$scope: scope
});
});
}
describe('#submit', function() {
beforeEach(function() {
_inject();
deferred = $q.defer();
spyOn(AuthService, 'changePassword').and.returnValue(deferred.promise);
spyOn($state, 'go');
});
describe('when email address is valid', function() {
it('should call the changePassword method on the AuthService', function() {
ctrl.submit(true);
scope.$digest();
expect(ctrl.submitted).toBe(true);
expect(AuthService.changePassword).toHaveBeenCalled();
});
});
});
});

Your spec code works for me (the real implementation of AuthService.changePassword doesn't get called): http://jsfiddle.net/7W2XB/7/
angular.module('example', [])
.factory('AuthService', function() {
return {
changePassword: function() {
throw new Error('Should not be called');
}
};
})
.controller('ChangePasswordCtrl', ['AuthService',
function(AuthService) {
var vm = this;
vm.submitted = false;
vm.submit = function(valid) {
vm.submitted = true;
if (!valid) return false;
AuthService.changePassword(vm.email)
.then(function(res) {
$state.go('reset.confirmation');
}, function(err) {
vm.hasError = true;
});
};
}
]);
describe('ChangePasswordCtrl', function() {
var ctrl, scope, AuthService, $q, deferred;
function _inject() {
module('ui.router');
module('example');
inject(function($controller, $rootScope, _AuthService_, _$state_, _$q_) {
scope = $rootScope.$new();
$state = _$state_;
$q = _$q_;
AuthService = _AuthService_;
ctrl = $controller('ChangePasswordCtrl', {
$scope: scope
});
});
}
describe('#submit', function() {
beforeEach(function() {
_inject();
deferred = $q.defer();
spyOn(AuthService, 'changePassword').and.returnValue(deferred.promise);
});
describe('when email address is valid', function() {
it('should call the changePassword method on the AuthService', function() {
ctrl.submit(true);
scope.$digest();
expect(ctrl.submitted).toBe(true);
expect(AuthService.changePassword).toHaveBeenCalled();
});
});
});
});
Some questions that might help make the JSFiddle more realistic to your situation: What versions of angular and Jasmine are you using? - How are you defining the AuthService (presumably using angular.factory)?
