开玩笑+超级测试异步回调未调用

问题描述

我已经完成了我的快速服务器的创建，并且正在使用Jest + Supertest来测试我的终结点并测试我的猫鼬数据库的所有CRUD操作。到目前为止，我什至无法在测试中创建新用户。

代码：

//server.spec.js
const supertest = require('supertest');
const server = require('./server');

describe('server.js',() => {
    describe('GET /',() => {
        it('should connect to server responding w/ 200',(done) => {
            return supertest(server)
            .get('/')
            .then(res => {
                expect(res.status).toBe(200);
                done();
            });
        });
    });

    describe('/api/users/',() => {
        it('should create a new user',async () => {
            return await supertest(server)
            .post('/api/users/register')
            .send({ username: "jest",email: "[e-mail]",password: "jestjest" })
            .set("Accept","application/json")
            .then(res => {
                console.log(res.body)
                expect(res.status).toBe(201)
            })
        })
    });
});

控制台输出：

我尝试了不同类型的解决方案，但没有成功。
