test example with 'before' starting server

[rauchg]

I wrote test-listen to make the job of passing a http server (as the one that could be returned by serve(async (req, res) => {}) from micro), and make it listen on a random ephemeral port.

Using ava:

import test from 'ava';
import listen from 'test-listen';

test('it works', async t => {
  // initialize `srv` using `serve` from `micro` first!
  const url = await listen(srv);
  t.ok(/http:\/\/localhost:\d+/.test(url));
  const data = await request(url);
  t.same('1', data);
});

Example:

Tnx! But than I would have to rewrite my code to fit the test...that's not what you meant, right?

Your example shows a simple export:

import {send} from 'micro-core'

export default async function(req, res) {
  send(res, 200, 'Ready!')
}

Which is served using the micro cli. So why use the micro cli at all if we have to write tests that consume serve'd functions?

I am disliking the convenience abstraction more and more...it obfuscates stuff and does not educate people, and it leads to maintenance you don't want

Why not just put out a great manual/stack on how to set it up without micro?

Nevermind, I figured it out...I can just start it with serve(listen(... in the test itself...

would be nice to have it in the readme tho ;)

@Morriz I agree it would be nice. Also having a complete project example repository with tests.
