promised-mongo: can't finalize promise

it should still fix some issue There are a few problems here:
You are creating several promises in a for loop, but not keeping track of them You have a DB.posts.insert that creates a promise, but you are not awaiting it
code :
return function(doc){
    if(doc) {
        console.log('skipping')
    } else {
        // here
        return DB.posts.insert(posts[i]).then(function() {
            console.log(arguments);
            nSaved++;
        });
    }
}
function ensurePost(post) {
    post.done = false;

    return DB.posts.findOne({
        "id" : post.id // it's 'id', not mongo's '_id'
    })
    .then(function(doc){
        if(doc) {
            console.log('skipping ' + post.id)
        } else {
            return DB.posts.insert(post).then(function() {
                console.log(arguments);
                nSaved++;
            });
        }
    })
    .catch(function(error){
        console.error('Error inserting', post.id, error);
    });
}

Promise.all(posts.map(ensurePost))
.done(function () {
    // all done. close the connection
});

How to check promise value and property updated in promise but not returned with chai-as-promised

hop of those help? the response should be used in parent scope.
and the assertion should be called after the promise is ready
code :
var response = {};
var resultPromise = authorizePromise(request, response);
return expect(resultPromise).to.eventually.equal(false)
    .then(function(){return response.statusCode.should.be(403)})

$promise stays promised on 'then' function

will be helpful for those in need The $resource service doesn't work when the response is a primative. It uses angular.copy to copy the data to the $resource object and angular.copy doesn't copy a primative to an object. It can only make deep copies of properties of other objects.

Chai as promised not waiting for promise to be fulfilled

To fix this issue This turned out to be a stupid typo. I typed fullfilled instead of fulfilled

Do I really need to return a promise in test when using Chai as Promised?

wish of those help In the case above Mocha chains returned promise after $rootScope.$apply() was called, so chained then needs another $rootScope.$apply() to be executed. Without this the rest of promise chain is not executed and results in timeout.
Returning promises in Mocha specs is intended for asynchronous specs, this is necessary for testing non-Angular promises. $q promises are synchronous and tied to Angular digests.
code :
chaiAsPromised.transferPromiseness = function (assertion, promise) {
  assertion.then = promise.then.bind(promise);

  if (!('$$state' in promise))
    return;

  inject(function ($rootScope) {
    if (!$rootScope.$$phase)
      $rootScope.$digest();
  });
};
