Testing hapi applications with lab

As I mentioned earlier, testing is considered paramount in the hapi ecosystem, with every module in the ecosystem having to maintain 100% code coverage at all times, as with all module dependencies.

Fortunately, hapi provides us with some tools to make the testing of hapi apps much easier through a module called shot, which simulates network requests to a hapi server. Taking our first example of the hello world server given in Chapter 1, Introducing hapi.js, let's write a simple test for it:

const Code = require('code');
const Lab = require('lab');
const Hapi = require('hapi');
const lab = exports.lab = Lab.script();
lab.test('It will return Hello World', (done) => {
  const server = new Hapi.Server();
  server.connection();
  server.route({
    method: 'GET',
    path: '/',
    handler: function (request, reply) {
      return reply('Hello World\n');
    }
  });
  server.inject('/', (res) => {
    Code.expect(res.statusCode).to.equal(200);
    Code...
