Pactum and Fastify

[leegee]

Is it possible to use Pactum against a Fastify server, in the manner of Supertest or the Fastify manual-recommended way, without having the server running? Currently ever test file is starting a server, and when run in parallel, of course the port is taken. Varying the server port seems the wrong with to go.

Hi 👋,

Can you let me know which test runner are you using?
Does your setup require you to run server instances for every test? If not (assuming you might be using mocha), you can start your fastify server in a before() and stop it in an after() global hooks of mocha. This way you just have to run one instance of your server before all tests begin on a single port.

Ex: add a base.spec.js

const server = require('./path-to-fastify-server');

// global hooks
before( () => {
  server.start(); // start fastify server before tests
});

after( () => {
  server.stop(); // if implemented for graceful shutdown
});

Hope this helps!

What test runner do you use for running tests?

@leegee Thanks for being patient. I have written and published a small plugin that will behave similar to supertest. Please give it a try and let us know the feedback.

Very nice, thank you -- having something published reassures some clients, and saves a lot of cut'n'paste and all the badness that entails.

A couple of points, if I may:

Might it be an idea to allow testing of hosts other than localhost?

Might it be safer to test for the test-runner hooks?

  if (typeof before === 'function') {
    before(start);
    after(stop);
  }

  else if (typeof beforeAll === 'function') {
    beforeAll(start);
    afterAll(stop);
  }

Or maybe just export start/stop so users can call them as needed (beforeEach, etc)? IDK

Again, thank you for your work.

Ahh.. this makes more sense. Thanks for your suggestions. Created issues to track them.
