u Shares requirements on Automotive Ethernet ECU testingof Conformance + Interoperability
u Defines specifications applicable to all ECUs in an Automotive Ethernet network based on these shared requirements.
u Defines test process and supports the establishment of test houses that can perform the ECU tests
u Establishes regular audits of the test specification and the partner requirements to increase the communication quality of the Ethernet ECUs and network in an automotive system
Target: Testing on ECU level as early as possible in the development phase

Target
u One Test System for all ISO/OSI layers but layer 1
u Test is available on any workbench
u Information exchange with colleagues is simple since all can share the same configuration
u This is true for the partial test execution as well as discussion of test results
Test System CANoe + vTESTstudio

Test Spec Example OABR_CABLE_01: Cable diagnostics for near and far end open
Exemplary Ethernet Test System
Source: OPEN Alliance TC8 Automotive Ethernet ECU Test Specification v2.0
Test Steps
1. The DUT cable diagnostic feature is triggered. The DUT cable diagnostics has to be executed within terror
2. The test system creates a cable error for a defined time terror
3. After the wait time t the test system reads out all identified cable errors QC from the DUT
4. Repeat step 1 to 3 for all error combinations (alternately MDI+ and/or MDI- are open)
Test Goal
Ensure that the DUT’s cable diagnostic reliably detects an open of one or both of the bus lines
