what should i do for error For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves

Question

I'm running a test using mocha

it('should allow a POST to /users', async function () {
        
        const res = await request.post('/users').send(firstUserBody);
    
        expect(res.status).to.equal(201);
        expect(res.body).not.to.be.empty;
        expect(res.body).to.be.an('object');
        expect(res.body.id).to.be.a('string');
        firstUserIdTest = res.body.id;
        
    });

but i have an error

Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves.

If I do it using done() the function is not async but it should be

it('should allow a POST to /users', async function (done) {

        const res = await request.post('/users').send(firstUserBody);

        expect(res.status).to.equal(201);
        expect(res.body).not.to.be.empty;
        expect(res.body).to.be.an('object');
        expect(res.body.id).to.be.a('string');
        firstUserIdTest = res.body.id;
        done();
    });

what should i do ?

I fixed code 2, if I make code like 2, 'await' gives an error. — yilmazoncum, Jun 22 '21 at 07:15
And _does_ the POST resolve in under 2s? Your test callbacks don't need to accept a done parameter if they're async. — jonrsharpe, Jun 22 '21 at 07:16
idk but it seems dont. i have Timeout of 2000ms exceeded error — yilmazoncum, Jun 22 '21 at 07:21
I hope you would have got a working solution. I have answered it here with `before`. https://stackoverflow.com/a/70200966/5375291 — Debu Shinobi, Dec 02 '21 at 14:31

There are two approaches of setting timeouts in Mocha:

(I would use a minimum of 20s when testing API calls)

Inside the test or describe block
```
describe('a suite of tests', function() {
  this.timeout(20000);
  ...
```
(be careful not to use an arrow function as that will cause this. to not work)

See: https://mochajs.org/#timeouts
Config level - .mocharc.js file or flag during runtime --timeout 20000 or even setting options with API (mocha.setup()).

I prefer using .mocharc.js. where you can put something like:
```
module.exports = {
  bail: true,
  timeout: 5 * 60 * 1000, // 5 minute timeout
  spec: ['specs/']
};
```

PS You should not need the done() with async functions
