# Local Policy Testing Tools

The documents linked below describe the tools and workflows for applying local
policies to a ChromeOS test device or a local Chrome build using
`fake_dmserver`.

There are two environments for these tools:

1. ChromeOS Device (DUT): For full OS-level policy testing.
2. Linux Desktop (Host): For rapid browser-level policy testing without a device.

Choose the workflow below that matches your environment.
