Seems we'd have to do ready and close ourselves regardless, which somewhat defeats the point... 🙁
That part has already been abstracted away. I want this library to make the test code as simple as possible. 😉
The issue is that fastify instances can’t be reused. I.e. the following code won’t work if multiple tests are present.
// app.js
import * as Fastify from 'fastify'
const app = Fastify();
app.get('/', async (request, reply) => {
reply.send({ hello: 'world' });
});
export default app;
// app.test.js
import { request, setTestApp } from 'axios-test-instance'
import app from './app'
beforeEach(() => setTestApp(app))
The following examples do work with the current PR. This is the same pattern as is used in their supertest example.
// createApp.js
import * as Fastify from 'fastify'
export default function createApp() {
const app = Fastify();
app.get('/', async (request, reply) => {
reply.send({ hello: 'world' });
});
return app;
}
// createApp.test.js
import { request, setTestApp } from 'axios-test-instance'
import createApp from './createApp'
beforeEach(() => setTestApp(createApp()))
// createApp.js
import * as Fastify from 'fastify'
export default function createApp() {
const app = Fastify();
app.get('/', async (request, reply) => {
reply.send({ hello: 'world' });
});
return app;
}
// createApp.test.js
import { request, setTestApp } from 'axios-test-instance'
import createApp from './createApp'
beforeAll(() => setTestApp(createApp()))
Because jest creates new instances for each test file when module isolation isn’t disabled, the following should also just work with jest.
// app.js
import * as Fastify from 'fastify'
const app = Fastify();
app.get('/', async (request, reply) => {
reply.send({ hello: 'world' });
});
export default app;
// app.test.js
import { request, setTestApp } from 'axios-test-instance'
import app from './app'
beforeAll(() => setTestApp(app))
If the scenario above meets your requirements, I’ll gladly finalize my changes and release them with a footnote about the quirks of using this library with fastify.

Thank you for your interest!
I gave it a try, but as you can see in the failing tests of the pull request, starting a fastify instance a second time, even after closing it properly, fails.
Also I’m not too happy about the framework detection mechanism I came up with.
I don’t think I’m going to dive much deeper into support for Fastify, but if someone else manages to fix it, I’ll gladly merge it.

In their docs, they have a supertest
example which gets passed the server
. Would that work, somehow?

Yeah, that should cover my use cases, thanks! I think documenting that behavior should be enough

This has been released as 3.1.0.

Thanks! It works great, except for https://github.com/remcohaszing/axios-test-instance/pull/3/files#r439827863
