有可能在hapi中使用supertest吗？

Question

我用的是哈皮，不是特快。超级测试还能用吗？

如果是这样的话，是否有一种快速的方法来更改我的代码以使其运行？

我的测试如下所示，基于文档

import tape = require('tape');
const supertest = require('supertest');
const app = require('../../../../src/app');

tape('creates new user in database', function (assert) {
  supertest(app)
    .get('/ekapi/v1/signup')
    .expect(200)
    ......
});

但它给了我一个错误：

dist/server/app/node_modules/supertest/lib/test.js:55
  var addr = app.address();
                 ^

TypeError: app.address is not a function
    at Test.serverAddress (/home/rje/projects/ekaya/dist/server/app/node_modules/supertest/lib/test.js:55:18)

这是我的应用程序代码：

app.ts

import './core/externalTypes/imports';
import 'reflect-metadata';
import kernel from './core/inversify.config';
import {IServer}  from './core/types/IServer';

let server = kernel.get<IServer>("IServer");
server.start();

server.ts

import _ = require('lodash');
import * as hapi from "hapi";
import { injectable, inject } from "inversify";
import { IServer } from "../core/types/IServer";
import { ISignUpRoute } from "../core/types/ISignUpRoute";
import { IRouteHandler } from "../core/types/IRouteHandler";
import { IDatabase } from "../core/types/IDatabase";
import { IConfig } from "../core/types/IConfig";
import { IValidator } from "../core/types/IValidator";

@injectable()
class Server implements IServer
{
    _db : IDatabase;
    _server: hapi.Server;
    _config: IConfig;
    _validator: IValidator;
    _routes: [IRouteHandler];

   constructor(
        @inject("IDatabase") db: IDatabase,
        @inject("IConfig") config: IConfig,
        @inject("IValidator") validator: IValidator,
        @inject("ISignUpRoute") signUpRoute: ISignUpRoute)
    {
        this._db = db;
        this._config = config;
        this._validator = validator;
        this._routes = [signUpRoute];
      this._server = new hapi.Server();
      this._server.connection({
          host: '0.0.0.0',
          port: this._config.webservice_port,
             routes: { cors: true }
      });
        this.addRoutes();
   }

    start() : void
    {
        this._server.start((err : any) => {
             if (err)
                  throw err;
             console.log('Hapi server running at: ', this._server.info.uri);
        });
    }

    addRoutes() : void {
        const self = this;
        this._routes.map(function(routeHandler : IRouteHandler) {
            self._server.route(routeHandler.getRoute());
        });
    }

}

export = Server;

埃斯特斯的回答奏效了。我需要在最外层的类hapi.Server中导出app.js。然后将其listener属性传递给tape。

然后，我不得不在测试结束时使用tape.onFinish( () => server.stop() );来停止服务器。

用js编写的用于测试的最小代码示例：

'use strict';

const Hapi = require('hapi');
const should = require('chai').expect
const request = require('supertest')


const server = new Hapi.Server();
server.connection({ port: 3000 });

server.route({
  method: 'GET',
  path: '/',
  handler: function (request, reply) {
    reply('Hello, world!');
  }
});

describe('server', function() {
  it('server', function(done) {
    request(server.listener).get('/').expect(200, function(err, resp) {
      should(resp.text).equal('Hello, world!')
      done()
    })
  })
})

如果"hapi": "^16"按原样工作的话。

如果是"hapi": "^8.1.0"，则需要手动运行server.start() ber前沿请求。
