Motivation

2009, PikeTec Folie 5TPT - Automatic ASAM MCD-3 supported test

What makes automotive testing special?

Coding / Code Generation

Modeling Target MCIntegration

ECUIntegration

CarIntegration

Feature 1: Tests must be portable and reusable

between the integration levels and technologies.

Functional refinement

Objective: Test refinement, instead of test rewriting !

Feature 2: Tests must handle signals,

parameters, and diagnosis in a simple way.

Test CaseBehavior

Feature 2: Tests must handle signals,

parameters, and diagnosis in a simple way.

Feature 3: Tests must be able to react to system behavior online (closed-loop tests).
