Test policy is a tool in the AWS Management Console, on the **Authorization** tab of your Client VPN endpoint, that you can use to test and develop your authorization policies. It presents the authorization policy, the device posture token context, and the user identity context on one screen, where you can test policies and make edits.

Device posture token formats vary across different trust providers, and you might not know the exact format a particular trust provider uses. Test policy shows you the trust context alongside your policy, so you can develop and test policies against real data.

The following sections describe how to use Test policy.
