# RemixTestPool

## Summary

Worker pool used by Remix to run server and E2E test files.
`'forks'` (default) uses child processes for stronger isolation; `'threads'`
uses worker threads for projects that prefer lower-overhead startup.

## Signature

type RemixTestPool = (typeof remixTestPools)[number]

```
