Embedded software differs from PC software because it is part of a product rather than the product itself, and its tasks range from automotive control units and industrial machines to life-sustaining medical devices. Testing embedded software requires understanding its unique challenges, including real-time behavior and hardware integration.
Readers will learn how to apply requirements engineering, ensure requirements traceability, and perform automated static analysis alongside professional code reviews. The book covers black-box testing techniques, unit tests, and integration tests to verify hardware/software interaction and system performance, helping readers navigate RTOS, middleware, and concurrency issues. It also shows how AI-based techniques are entering the field of embedded testing.
By the end of this book, readers will be equipped to design, implement, and manage testing strategies for both low and high-integrity embedded software. They will develop a comprehensive understanding of the essentials of test management, quality management standards like ISO 9001, and CMMI. The exercises and solutions will be valuable in gaining the skills needed to tackle complex testing challenges.
What you will learn
● Implement unit tests and coverage.
