gengojs-wrappify

gengojs-wrappify

An Express, Hapi, an Koa wrapper for the core of gengojs. This module should be used when you need to test your gengojs plugins that need or use the request object.

The following is an example that shows you to:

• Make sure the plugin has properly loaded
• Make sure that the internal API is properly exposed.
• Make sure that the internal API's API are exposed as well.

Note that there are two version of Wrappify. One is without es6 and the other is. The example below is with ES6. Therefore, make sure to use the --harmony flag when running your tests or use Babel to convert your ES6 code to ES5.

Also note that the wrapper for koa only supports Koa >= v2.0.0.

var assert = require('chai').assert;
var core = require('gengojs-core');
var header = require('your plugin path');
// Wrappify with harmony
// (without harmony would simply be require('gengojs-wrappify'))
var wrappify = require('gengojs-wrappify/es6');

describe('Header', function() {
  describe('load plugins', function() {
    it('should exist', function() {
     // Create an instance of the core.
      var gengo = core({}, header());
      gengo.plugins.headers.forEach(function(plugin) {
        assert.isDefined(plugin);
        assert.strictEqual(plugin.package.type, 'header');
        assert.strictEqual(plugin.package.name, 'gengojs-default-header');
      });
    });
  });
  describe('koa', function() {
    var gengo = core({}, header());
    var Koa = require('koa');
    var app = new Koa();
    // Use Koa wrapper
    app.use(wrappify(gengo).koa());
    var request = require('supertest');
    it('should have the api exposed internally', function() {
      request(app.listen()).get('/').end(function() {
        assert.isDefined(gengo.header);
        assert.isDefined(gengo.header.getLocale);
      });
    });
  });

  describe('express', function() {
    var gengo = core({}, header());
    var express = require('express');

    app.use(wrappify(gengo).express());

        assert.isDefined(gengo.header);
        assert.isDefined(gengo.header.getLocale);
      })
    });
  });

  describe('hapi', function() {
    var gengo = core({}, header());
    var Hapi = require('hapi');
    var server = new Hapi.Server();
    server.connection({
      port: 3000
    });
    // Register Hapi wrapper
    server.register(wrappify(gengo).hapi(), function(err) {});

    it('should have the api exposed internally', function() {
      server.inject('/', function(res) {
        assert.isDefined(gengo.header);
        assert.isDefined(gengo.header.getLocale);
