== Policy Evaluation Tool

When designing your policies, you can simulate authorization requests to test how your policies are being evaluated.

You can access the Policy Evaluation Tool by clicking the `Evaluate` tab when editing a resource server. There you can specify different inputs to simulate real authorization requests and test the effect of your policies.

=== Providing Identity Information

The *Identity Information* filters can be used to specify the user requesting permissions.

You can also click *Entitlement* to obtain all permissions for the user your selected.

=== Providing Contextual Information

The *Contextual Information* filters can be used to define additional attributes to the evaluation context, so that policies can obtain these same attributes.

=== Providing the Permissions

The *Permissions* filters can be used to build an authorization request. You can request permissions for a set of one or more resources and scopes. If you want
to simulate authorization requests based on all protected resources and scopes, click *Add* without specifying any `Resources` or `Scopes`.

When you've specified your desired values, click *Evaluate*.
