Jasmine unit tests with odata promises - angularjs

Question

I'm new at angular and at unit testing with angular. We are using odata for database CRUD actions, so we have created a service for that, looks like this:
function DatabaseService($http, $odataresource, DateFactory, constants) {
var url = constants.BACKEND.URL;
var ObjCreate = $odataresource(url + 'Objects/Function.CreateObject', {}, {}, {});
var service = {
createSomething: {
createObj: createObj
}};
return service;
function createObj(formData) {
var myObj = new ObjCreate();
mapData(formData, myObj );
return myObj.$save();
}
The code is a bit abstracted for my question, so don't wonder please. I want to unit test the function createObj() now, which doesn't work. I took an angular class and we learned there that for 'execute' promises we have to use $rootScope.digest(), but it doesn't seem to work in my case:
describe('createObj', function () {
it('should return data', inject(function ($rootScope) {
var DatabaseService = $injector.get('DatabaseService', { $odataresource: $odataresource });
var formDataMock = {
productName: "Produktname"
};
var test = 'abc';
DatabaseService.createSomething.createObj(formDataMock)
.then(function (data) {
test = data;
})
.catch(function (error) {
test = error;
});
$rootScope.$digest();
console.log(test);
}));
I have added the setting of the variable test to see when for example the then path is executed, but even with the $rootScope.$digest it will never step into the then path, my variable test will never change from 'abc' to something else.
Could you please give me a hint what am I doing wrong?

I tried to update your code to use the done Feature of Jasmine 2.0.
http://ng-learn.org/2014/08/Testing_Promises_with_Jasmine/
describe('createObj', function () {
it('should return data', function (done) {
var DatabaseService = $injector.get('DatabaseService', { $odataresource: $odataresource });
var formDataMock = {
productName: "Produktname"
};
var test = 'abc';
DatabaseService.createSomething.createObj(formDataMock)
.then(function (data) {
test = data;
})
.catch(function (error) {
test = error;
})
.finally(done);;
console.log(test);
});
