chai-as-promised

I'm trying to write a test to test a method that connects to mongo, but I don't actually want to have to have mongo running and actually make a connection to it to have my tests pass successfully. Here's my current test which is successful when my mongo daemon is running. describe('with a valid mongo string parameter', function() { it('should return a rejected promise', function(done) { var con = mongoFactory.getConnection('mongodb://localhost:27017'); expect(con).to.be.fulfilled; done(); }); }); mongoFactory.getConnection code: getConnection: function getConnection(connectionString) { // do

Chai as Promised documentation states as follows: Notice : either return or notify(done) must be used with promise assertions. And the examples on the site are as follows: return doSomethingAsync().should.eventually.equal("foo"); doSomethingAsync().should.eventually.equal("foo").notify(done); The thing is; I actually wrote a test using chai as promised without returning the promise. Like so: it('should resolve user', function () { $state.get(state).resolve.user(dataservice, { userId: testUser.id }).should.eventually.eq(testUser); $rootScope.$apply(); }); And it works perfectly fine. I am sure
