Unit Test function that returns a Mongoose promise

Question

for check

import { User } from '../models/no-sql/user'; function userCreate(req) { const user = new User({ username: req.username, password: req.password }); return user.save(); } app.get('/userCreate', function(req, res) { User.findOne({ username: req.username }).lean().exec((err, data) => { if(data){ userCreate(req).then(function() { // success }, function(err) { // error }); }else{ // no user found } }); }); 

unit test

  require('sinon-as-promised'); import request from 'supertest'; const user = { username: newUserName, password: 'password' }; factory.build('user', user, function(err, userDocument) { UserMock. expects('findOne').withArgs(sinon.match.any) .chain('lean') .chain('exec') .yields( null, undefined); const docMock = sinon.mock(userDocument); docMock.expects('save') .resolves([]); request(app) .post('/userCreate') .send({username: newUserName, password: 'password') .expect(200) .end((err, res) => { if(err) done(err); should.not.exist(err); should.equal(res.body.success, true); done(); }); }); 

the test comes to the return of user.save (), then the time runs out. It seems that I am missing something in unit tests, but the error does not occur. I use sinon, as I promised to resolve the promise, but does not seem to see it.

It seems unlikely that you intentionally refused to call res.send () in your code example for the sake of brevity.

Just to make sure you return a 200 status code when the userCreate function called on the router succeeds?

 userCreate(req).then(function() { // success res.status(200).send('User created successfully'); }
