As far as testing goes I couldn't find much material on how to go about and test my API with, say something like Mocha. I suppose I could've just browsed the hapi source code and see how it was tested internally, but what I ended up doing (after some googling) was that I'd actually start the hapi server before each test case and then stop it after each test. In the tests I used mikeal's request library to query the API. This worked but it felt a bit awkward compared to, for example, what Django provides.
Luckily, I ran into Eran's great talk about hapi where he briefly mentions the server.inject() method. I remember seeing that method before but didn't really understand what it would be good for. But actually with that method you can easily build your API tests. So, I created a generic function for querying my API:
/**
* @param {hapi.Server} server - hapi server instance
* @param {object} requestobj - options for making the request
*/
exports.request = function (server, requestobj, callback)
server.inject(requestobj, function (res)
if (res.payload)
res.body = JSON.parse(res.payload);
}
callback(res);
});
In the tests I would do something like this (note that the following test uses Mocha but any test framework should do just fine):
beforeEach(function (done) {
var api = require('../api/api.js');
this.server = api.createServer();
done();
});
it('should GET all players', function (done) {
var request = { url: '/player/', method: 'GET' };
test.request(this.server, request, function (res) {
res.statusCode.should.be.equal(200);
res.body.length.should.be.equal(6);
done();
});
});
And that was it. No more starting and stopping the server all the time.
