Remarks
The .test top-level domain is reserved against usage in the global Domain Name System so it may be used in software testing and other related purposes. As names under .test do not resolve to real services or conflict with registered domains, they can be used safely in testing environments without generating unintended traffic or raising privacy concerns.

For further information, see Special-Use Domain Names (RFC 6761) and Reserved Top Level DNS Names (RFC 2606).
