javascript - 如何在nodejs上为postgresql数据库编写单元测试

Question

我正在尝试使用 postgresql 为我的 API 编写测试。

测试似乎没有命中正确的数据库以进行响应，或者我的配置可能不适合测试。

我希望测试检查我的 token 并将其视为来自正文的请求，但测试甚至无法识别请求正文 (req.body)；

我需要指导。

我的文件如下。 测试.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();
  });
 });

我的数据库配置

import pg from 'pg';

import dotenv from 'dotenv';

dotenv.config();

process.env.NODE_ENV = 'test';

let connection;
const string = {
  user: process.env.DB_USER,
  host: process.env.DB_HOST,
  database: process.env.DB_NAME,
  password: process.env.DB_PASS,
  port: process.env.DB_PORT,
  max: 10,
  idleTimeoutMillis: 3000,
};
const stringTest = {
  user: process.env.DB_USER,
  host: process.env.DB_HOST,
  database: process.env.DB_NAME2,
  password: process.env.DB_PASS,
  port: process.env.DB_PORT,
  max: 10,
  idleTimeoutMillis: 3000,
};
if (process.env.NODE_ENV === 'production') {
  connection = {
    connectionString: process.env.DATABASE_URL,
    ssl: true,
  };
} else if (process.env.NODE_ENV === 'test') {
  connection = stringTest;
} else {
  connection = string;
}
const pool = new pg.Pool(connection);

export default pool;

我能够通过在测试套件中的 post 方法下设置授权来解决这个问题 .set('授权', token)
