How to write unit test for postgresql database on nodejs

Question

I am trying to write test for my API with postgresql.

It seem the test is not hitting the right database for response or maybe my configuration is not proper for the test.

I expect the test to check my token and treat as req from a body but the test is not even recognizing the request body (req.body);

Please I need guidance.

my files are as below. test.js

/* global describe it */
import chai, { expect, assert } from 'chai';

import chaiHttp from 'chai-http';

import jwt from 'jsonwebtoken';

import server from '../app/app';

import parties from '../db/dummy';

process.env.NODE_ENV = 'test';

chai.should();
chai.use(chaiHttp);

const token = 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpZCI6MSwiZW1haWwiOiJ0b3NpbkB5YWhvby5jb20iLCJpc19hZG1pbiI6dHJ1ZSwiaWF0IjoxNTQ5Mjc3MzAxLCJleHAiOjE1NDkzNjM3MDF9.ZJl147IVpw3TakPnR4uw_y6ZQZ6-Heoup5bdBBPs0iE';
const decoded = jwt.verify(token, process.env.SECRET_KEY);

describe('POST/api/v1/parties', () => {
  it('should return 201 for new party', (done) => {
    const newParty = {
      name: 'APGC',
      hqAddress: '1 Iyana Iba ',
      logoUrl: 'www.logo.net.png',
      decoded,
    };
    chai.request(server)
      .post('/api/v1/parties')
      .type('form')
      .send(newParty)
      .end((err, res) => {
        expect(decoded).be.a('string');
        expect(res.body).to.have.property('data');
        assert.isOk(res.body);
      });
    done();
  });
 });

} else {

}
const pool = new pg.Pool(connection);

export default pool;

我可以通过在测试套件.set('Authorization', token)的post方法下设置授权来解决此问题
