 ## Test isolation

+By default each test file is run in a new worker thread. You can fall back running in separate processes.
 
 AVA will set `process.env.NODE_ENV` to `test`, unless the `NODE_ENV` environment variable has been set. This is useful if the code you're testing has test defaults (for example when picking what database to connect to). It may cause your code or its dependencies to behave differently though. Note that `'NODE_ENV' in process.env` will always be `true`.

 ## Requirements
 
-AVA 5 uses [`chokidar`] as the file watcher. Note that even if you see warnings about optional dependencies failing during install, it will still work fine.

-Otherwise, AVA 6 uses `fs.watch()`. Support for `recursive` mode is required. Note that this has only become available on Linux since Node.js 20. [Other caveats apply](https://nodejs.org/api/fs.html#caveats), for example this won't work well on network filesystems and Docker host mounts.

 ## Ignoring changes
 
 By default AVA watches for changes to all files, except for those with a `.snap.md` extension, `ava.config.*` and files in [certain directories](https://github.com/novemberborn/ignore-by-default/blob/master/index.js) as provided by the [`ignore-by-default`] package.
