"A fetch response body was created during the test" when invoking a PUT request in a test?

I'm writing a Deno library for uploading files on IPFS. The code is very simple:

export const uploadCar = async ({ file, url }) => {
  const res = await fetch(url, {
    method: 'PUT',
    body: file,
    headers: { 'x-amz-meta-import': 'car' },
  })

  return res.headers.get('x-amz-meta-cid')!
}

export const uploadCar = async ({ file, url }) => {
  const res = await fetch(url, {
    method: 'PUT',
    body: file,
    headers: { 'x-amz-meta-import': 'car' },
  })

  return res.headers.get('x-amz-meta-cid')!
}

And this is the test file I have:

import { CAREncoderStream, createFileEncoderStream } from 'https://esm.sh/ipfs-car@1.0.0'
import { CID } from 'https://esm.sh/multiformats@12.1.3/cid'

async function streamToBlob(stream: ReadableStream): Promise<Blob> {
  const reader = stream.getReader()
  const chunks: Uint8Array[] = []

  while (true) {
    const { done, value } = await reader.read()
    if (done) break
    chunks.push(value)
  }

  return new Blob(chunks, { type: 'application/octet-stream' })
}

describe('uploadCar', () => {
  it(
    'should upload a CAR file',
    async () => {
      const stream = createFileEncoderStream(new Blob(['Hello ipfs-car!']))
        .pipeThrough(
          new TransformStream(),
        )
        .pipeThrough(new CAREncoderStream([placeholderCID]))

      const blob = await streamToBlob(stream)

      const file = new File([blob], 'file.car')

      const cid = await uploadCar({ file, ...args })

      assertEquals(cid, 'bafybeigdyrzt5sfp7udm7hu76uh7y26nf3efuylqabf3oclgtqy55fbzdi')
    },
  )
})

import { CAREncoderStream, createFileEncoderStream } from 'https://esm.sh/ipfs-car@1.0.0'
import { CID } from 'https://esm.sh/multiformats@12.1.3/cid'

async function streamToBlob(stream: ReadableStream): Promise<Blob> {
  const reader = stream.getReader()
  const chunks: Uint8Array[] = []

  while (true) {
    const { done, value } = await reader.read()
    if (done) break
    chunks.push(value)
  }

  return new Blob(chunks, { type: 'application/octet-stream' })
}

describe('uploadCar', () => {
  it(
    'should upload a CAR file',
    async () => {
      const stream = createFileEncoderStream(new Blob(['Hello ipfs-car!']))
        .pipeThrough(
          new TransformStream(),
        )
        .pipeThrough(new CAREncoderStream([placeholderCID]))

      const blob = await streamToBlob(stream)

      const file = new File([blob], 'file.car')

      const cid = await uploadCar({ file, ...args })

      assertEquals(cid, 'bafybeigdyrzt5sfp7udm7hu76uh7y26nf3efuylqabf3oclgtqy55fbzdi')
    },
  )
})

When running this test this is what Im getting:

uploadCar ... should upload a CAR file => https://deno.land/std@0.207.0/testing/_test_suite.ts:323:15
error: Leaking resources:
  - A fetch response body (rid 18) was created during the test, but not consumed during the test. Consume or close the response body `ReadableStream`, e.g `await resp.text()` or `await resp.body.cancel()`.

I couldn't find much info about the issue - what could be a possible fix?

error: BadResource: Bad resource ID

I'm writing tests for https://github.com/deno-libs/tinyhttp/pull/9.

import { describe, expect, it, run } from 'https://deno.land/x/tincan@1.0.1/mod.ts'
import { App } from '../../app.ts'

describe('Request properties', () => {
  it.only('should have default HTTP Request properties', async () => {
    const app = new App()
    app.get('/', (req, res) => {
      res.json({ url: req.url })
    })
    const listener = Deno.listen({ port: 8080, hostname: 'localhost' })

    setTimeout(() => {
      fetch(`http://localhost:8080`).then((res) => res.json()).then((json) => {
        expect(json).toEqual({ url: `http://localhost:8080/` }) 
      })
    }, 0)

    const conn = await listener.accept()
    const requests = Deno.serveHttp(conn)
    const { request, respondWith } = (await requests.nextRequest())!
    const response = await app.handler(request, conn)
    if (response) {
      respondWith(response)
      // Deno.close(conn.rid)
      
      listener.close()
    }
  })
})

import { describe, expect, it, run } from 'https://deno.land/x/tincan@1.0.1/mod.ts'
import { App } from '../../app.ts'

describe('Request properties', () => {
  it.only('should have default HTTP Request properties', async () => {
    const app = new App()
    app.get('/', (req, res) => {
      res.json({ url: req.url })
    })
    const listener = Deno.listen({ port: 8080, hostname: 'localhost' })

    setTimeout(() => {
      fetch(`http://localhost:8080`).then((res) => res.json()).then((json) => {
        expect(json).toEqual({ url: `http://localhost:8080/` }) 
      })
    }, 0)

    const conn = await listener.accept()
    const requests = Deno.serveHttp(conn)
    const { request, respondWith } = (await requests.nextRequest())!
    const response = await app.handler(request, conn)
    if (response) {
      respondWith(response)
      // Deno.close(conn.rid)
      
      listener.close()
    }
  })
})

When running this test I get either this:

Request properties > should have default HTTP Request properties => https://deno.land/x/tincan@1.0.1/src/runner.ts:166:10

or this, if I uncomment that line:

I'm trying to make Hardhat CLI work with Deno but I stumbled upon this error which comes from Deno: I initialized a new hh project pnpx hardhat init then installed hh as a deno binary:

➜ deno install -Afq npm:hardhat

➜ deno install -Afq npm:hardhat

and got this:

Closing a websocket server in a unit test

Hello, I'm an author of rpc lib and I'm currently writing unit tests for it. I am facing a problem of closing a server. How should I do it without deno hanging forever? my test case:

import { send, App } from './mod.ts'

Deno.test('send', async (t) => {
  await t.step('should send a message with websocket', async () => {
    const app = new App()
    await app.listen({ port: 8881, hostname: 'localhost' })

    const socket = new WebSocket('ws://localhost:8881')
    socket.onopen = () => {
      send(socket, { hello: 'world' })
      socket.close()
      app.close()
    }
  })
})

import { send, App } from './mod.ts'

Deno.test('send', async (t) => {
  await t.step('should send a message with websocket', async () => {
    const app = new App()
    await app.listen({ port: 8881, hostname: 'localhost' })

    const socket = new WebSocket('ws://localhost:8881')
    socket.onopen = () => {
      send(socket, { hello: 'world' })
      socket.close()
      app.close()
    }
  })
})

app.listen here both starts the Deno.listener and Deno.serveHttp
