Description

When I run unit tests by fastify.inject, it timeout after several requests.

- event compiled client and server successfully in 639 ms (151 modules)
      1) should create user with admin role
- event compiled client and server successfully in 311 ms (151 modules)
      ✔ should create normal user (1291ms)
    login
      2) should login admin user
      3) should login normal user
    me
      4) should return admin user
      5) should return normal user

  1 passing (11s)
  5 failing

  1) User
       createUser
         should create user with admin role:
     Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done()" is called; if returning a Promise, ensure it resolves. (C:\Users\user\project\git\api2\dist\__tests__\index.js)
      at listOnTimeout (node:internal/timers:573:17)
      at process.processTimers (node:internal/timers:514:7)

Steps to Reproduce

I run test with the following

server.inject({
  method: "POST",
  url: "/graphql",
  payload: { query: print(documentNode), variables },
  headers: authToken
    ? { authorization: `Bearer ${authToken}` }
    : undefined
});

Expected Behavior

The tests do not timeout

Thanks for reporting!

Can you provide steps to reproduce? We often need a reproducible example, e.g. some code that allows someone else to recreate your problem by just copying and pasting it. If it involves more than a couple of different file, create a new repository on GitHub and add a link to that.

Example: https://github.com/joshuaavalon/fastify-nextjs-bug

1. npm i
2. npm run start

Expect the script to stop after 1 is print, however, it does not stop.

The expected behavior is what commenting out await app.register(nextPlugin); in index.js.

Apparently we have not tests using inject(), so it's likely possible this would never work or it would not be possible to make it work.

My current workaround is just to not register this plugin when using inject.
