Testability Protocol and Service Primitives
AUTOSAR TC Release 1.1.0

Introduction and Functional Overview
This document details the specification of a communication control protocol with the
objective of triggering service primitives (Service Primitives) that imply actions or
observations on an implantation under test (IUT). To trigger the actions and
observations a testability module/upper tester (UT) that implements the service
primitives is located inside the device under test (DUT). The control communication
using this protocol takes place on the control channel (CC) between Test System and
UT. The actions and observations are exercised through the upper interface that the
IUT exposes to its upper layers, the upper test channel (UC). The actions are
intended to cause the IUT to communicate with the lower tester (LT) on the lower test
channel (LC), wherein the test system verifies the IUT behavior. The test system can
also stimulate the IUT to negative scenarios in order to validate the robustness of the
IUT. There are several ways to setup the test environment.

4 Constraints and Assumptions
4.1 Limitations
Although the testability protocol format is compatible to the SOME/IP protocol the
message exchange behavior is different. “Request/response” communication is
supported but extended by optional notification events. There is no “fire and forget” or
“publish/subscribe” communication.
A secure mechanism to prevent unauthenticated access to service primitives is not
part of this document but should be realized.
4.2 Applicability to car domains
There are no known dependencies to certain car domains.
