Effective test strategy for testing automotive software

Electronic content is increasing in automobiles day by day. Functionalities like Air Bags, Anti-lock Braking, Driver Assistance Systems, Body Controllers, Passive entry Passive Start, Electronic Power Steering etc. are realized electronically with complex software. These functionalities are related to automobile system safety. Hence, safety is one of the key issues of future automobile development. Risk of system failure is high due to increasing technological complexity and software content. The software shall be tested well to arrest almost all the defects. This paper explains a test case development and execution strategy based on practical implementation. It explains how test case reduction using Taguchi method, prioritization of test execution and automation help to make testing effective. It also demonstrates how maximum defects are discovered in short time.
