Embedded Systems Testing
Software testing is the process of checking software, to verify that it satisfies its requirements and to detect errors. Software testing is an empirical investigation conducted to provide stakeholders with information about the quality of the product or service under test[1] , with respect to the context in which it is intended to operate. This includes, but is not limited to, the process of executing a program or application with the intent of finding software bugs. Testing can never completely establish the correctness of computer software. Instead, it furnishes a criticism or comparison that compares the state and behaviour of the product against a specification. Software testing should be distinguished from the separate discipline of Software Quality Assurance (S.Q.A.), which encompasses all business process areas, not just testing.
Embedded systems is gaining importance with increasing adoption of 16 and 32-bit processors across a wide variety of electronic products. As consumer expectation from these systems grow, manufacturers are challenged with the following factors before testing this to perfect for market release:
- Real time responses
- Separate host (target) systems from development environments
- Lack of standardization in deployment architectures
- Lack of established interfaces to systems under testing
- Stringent Fail-Safe requirements
- Extremely high cost of isolating and fixing defects

Model-Based Testing for Embedded Systems
"As model-based testing is entering the mainstream, such a comprehensive and intelligible book is a must-read for anyone looking for more information about improved testing methods for embedded systems. Illustrated with numerous aspects of these techniques from many contributors, it gives a clear picture of what the state of the art is today."
- Clarifies theory and practice associated with test specification and validation of complex software-intensive embedded systems
- Includes detailed examples from industry to illustrate real-world solutions
- Provides a global view of the current practices in Model-Based Testing, helping engineers choose the most appropriate solution
- Presents model-based testing from various perspectives, combining aspects of embedded systems and software
