Testtp

A library that simplifies testing with node http.Server's or listeners like express. It exposes node-fetch (bitinn/node-fetch) to get data from the test server.

Install

npm install --save-dev testtp

Usage

A sample jest test.

var http = require('http')
var express = require('express')
var fetch = require('node-fetch')
var createTestServer = require('testtp');

describe('tests', () => {

  it('test', async () => {

    // given
    var app = express().get('/', (req, res) => res.send('OK'));

    // returns a Testtp instance
    var test = await createTestServer(app);

    expect(test._server).toEqual(expect.any(http.Server));
    expect(test.port).toEqual(expect.any(Number));
    expect(test.address).toBe('127.0.0.1');
    expect(test.url).toBe(['http://127.0.0.1', test.port].join(':'));

    // when
    var res = await test.get('/');
    var text = await res.text();

    // then
    expect(res.status).toBe(200);
    expect(text).toBe('OK');

    // after
    await test.close();
  });
});
