node.js - Testing node js router with with chai and supertest fails -

i trying test post request takes in information , saves mysql database.

here router.

router.post('/dbinsert',(req,res,next)=>{    user = req.body;    saveuser(user).then((result)=>{        res.send('all info saved');     }).catch((e)=>{        res.send('all info not saved');    }); }); 

the router works since tried post data it.

so when trying run test, says error. here test.

describe('post /dbinsert',()=>{     it('should create new user',(done)=>{         var fake = {             owner : "3",             firstname : "bla",             lastname : "wassup",             email:"unvalid@email.com",             password : "akhjashjkdadh",             token : "121212121"         }         request(app)             .post('/dbinsert')             .send(fake)             .expect(200)             .expect((res)=>{                 expect(res.body).to.include(fake);             })              .end((err,res)=>{                 if(err)                     return done(err);             });     }); }); 

here error.

1 failing    1) post /dbinsert should create new user:      assertionerror: expected {} have property 'owner' 

/* not related above question curious */

i new , wanted ask, how can database cloned, in not test on own database have fake database tests , gets deleted. looked @ spy, din't know if thats way it.

supertest test not behaving think. not unit test sent server. tests response server, it's not going object sent.

.expect((res)=>{     expect(res.body).to.include(fake); }) 

if call res.send(body) in route, should able validate this:

.end((err, res) => {     if (err) return done(err);     expect(res.body).to.have.property("owner").that.equal("3");     return done(); }) 

another issue see you're not handling errors properly. in case, you're sending 200 in event of error, meaning don't know when fails , that's why updated validation doesn't seem work properly.

.catch((e)=>{ // difference message. res.send('all info not saved'); });

try this:

.catch((e)=>{ // now, 500 note failure res.status(500).send(e.message); });

this going timeout when successful because you're going call done when there's error. remove if statement.

.end((err,res)=>{     if(err)         return done(err); }); 

this should work:

.end(done); 

the whole shibang:

router.post('/dbinsert',(req,res,next)=>{    user = req.body;    saveuser(user).then((result)=>{        res.send(user);        next();     }).catch((e)=>{        res.status(500).send(e.message);        next();    }); });  describe('post /dbinsert',()=>{     it('should create new user',(done)=>{         var fake = {             owner : "3",             firstname : "bla",             lastname : "wassup",             email:"unvalid@email.com",             password : "akhjashjkdadh",             token : "121212121"         }         request(app)             .post('/dbinsert')             .send(fake)             .expect(200)             .end((err, res) => {                 if (err) return done(err);                 expect(res.body).to.have.property('owner').that.equal(fake.owner);                 done();             });     }); }); 

to test, verified works:

const request = require('supertest'); const express = require('express'); const bodyparser = require('body-parser'); const expect = require('chai').expect; const app = express();  app.use(bodyparser.json());  app.post('/user', function(req, res) {   return res.send(req.body); });  request(app)   .post('/user')   .send({       foo: "bar"   })   .expect(200)   .end(function(err, res) {     if (err) throw err;     expect(res.body.foo).to.equal("bar");   }); 

if it's still not working, there must unseen going on. try console.dir(res.body) if doesn't work @ output.
