Test Strategy and Test Case Design for an Automated, ‘To Order’, Configuration System for an Electronic Controller 2001-01-2771

The test strategy, test design and test case development for a ‘to order’ configuration system for a configurable electronic control system for a heavy-duty vehicle are discussed. The issues in test case design, to maximize test coverage for a highly combinatoric configuration capability, are reviewed. Then, the role played by the Electronics Integration Test Station [EITS] to evaluate test items as an element of test case design and conducting the tests is reviewed. EITS provides a hardware-in-the-loop test facility for evaluating vehicle electronic control systems. Finally, the coverage achieved is compared with the coverage required as determined by analysis of the order content of vehicles and the analysis of the configurable electronic control system design information.
