MongoMemoryReplSet hangs tests in Bun

[robertherber]

Versions

• NodeJS: N/A
• mongodb-memory-server-*: 8.15.1
• mongodb(the binary version): 5.0.19
• mongodb(the js package): 5.9.0
• system: MacOS 13.5.2

package: mongo-memory-server

What is the Problem?

When running bun test it hangs on mongodb.stop(). It does work with MongoMemoryServer but not with MongoMemoryReplSet.

Code Example

import {
  expect, beforeAll, test, afterAll,
} from 'bun:test'

let mongodb
beforeAll(async () => {
  const memoryServer = await import('mongodb-memory-server')
  mongodb = await memoryServer.MongoMemoryReplSet.create()
})

test('a test', () => {
  expect(1 + 1).toEqual(2)
})

afterAll(async () => {
  console.log('stopping mongodb')
  await mongodb.stop() // <-- hangs here
  console.log('stopping mongodb')
})

Not sure why it happens, and not really getting any useful output. This issue might very well belong in the bun repo. I'm happy to move the issue there - but any context as to what could be different between the two implementations might be helpful when moving it there :)

please provide Debug Output

also note that other engines other than nodejs are not officially supported, though deno is tested through mongoose (not the full suite though) and a lot of issues (mostly inside the mongodb driver) have come up with deno

also maybe try the latest beta 9.0.0-beta.2
