Identification

Field	Value
Test case name	Authorization through authorization cache - AuthCacheDisablePostAuthorize
Test case Id	TC_C_57_CS

Requirement(s)	C12_FR_05, C10_FR_03
System under test	Charging Station
Functional block	C. Authorization

Description

This test case describes how the EV Driver can be authorized to start a transaction by using Cached IdTokens. This enables the EV Driver to start a transaction while the Charging Station is online by using the Authorization Cache in which case the Charging Station can respond faster, since no AuthorizeRequest is being sent. For an IdToken that does not have status "Accepted" the Charging Station will still send an AuthorizeRequest to check against the most recent status from CSMS. However, when the setting AuthCacheDisablePostAuthorize is set to true, then the Charging Station will not do this.

Purpose

To verify that the Charging Station will not send an AutorizeRequest for an IdToken in the Authorization Cache that is not "Accepted", when AuthCacheDisablePostAuthorize is set to true.

Prerequisite(s)

AuthCacheCtrlr.Available is implemented with value true
AuthCacheCtrlr.DisablePostAuthorize is implemented

Before (Preparations)

Configuration State:

AuthCacheCtrlr.Enabled is true (If implemented) AuthCtrlr.LocalPreAuthorize is true (If implemented) AuthCacheCtrlr.DisablePostAuthorize is true

Memory State:

IdTokenCached for <Configured invalid IdToken fields>

Reusable State(s):

State is EVConnectedPreSession

Main (Test scenario)

Charging Station	CSMS
Manual Action: Present Invalid idToken which is already configured in the Authorization Cache
1. The Charging Station does NOT send a AuthorizeRequest

Tool validations

Step 1:

Check that Charging Station does NOT send an AuthorizeRequest and authorization is refused.
