supertest times out on post request

i'm trying to use supertest to test some express routes, however the test throws a timeout error when i try to send post requests despite the get requests actually working.

this is the route i'm testing

router.post('/', async (req, res) => {
  try {
    const { command, text } = req.body;

    switch (command) {
      case 'abc': return;
      default:
        console.log('123');
    }
  } catch (error) {
    console.error(error);
  }
});

this is the test

describe('test', () => {
  const app: express.Express = express();
  app.use('/', route);
  app.use(express.urlencoded({ extended: true }));

  it('test', async () => {
    await request(app)
      .post('/')
      .send('command=john') 

    expect(handleSurveyListCommand).not.toHaveBeenCalled();
    expect(handleSurveyRespondCommand).not.toHaveBeenCalled();
    expect(consoleErrorSpy).toHaveBeenCalledTimes(1);
    expect(consoleErrorSpy).toHaveBeenCalledWith(new Error('Command not found'));
  });
});

and this is the error thrown

Timeout - Async callback was not invoked within the 5000 ms timeout specified by jest.setTimeout.Timeout - Async callback was not invoked within the 5000 ms timeout specified by jest.setTimeout.Error:

this test fails even if the only thing i do inside the route is to log something.

This is because you are not responding back with the response while the request in test case is waiting for some response, instead return try sending response

router.post('/', async (req, res) => {
  try {
    const { command, text } = req.body;

    switch (command) {
      case 'abc': res.status(200).send("abc");
      default:
        res.status(200).send("123");
    }
  } catch (error) {
    res.status(500).send("unknown error");
  }
});

Regarding req.body undefined ->use body parsed in app

app.use(express.bodyParser());
