EXTENSIBLE DESIGN PATTERNS BASED OBJECT-ORIENTED FRAMEWORKS USING SCENARIO TEMPLATES FOR TESTING EMBEDDED SYSTEMS

摘要

Testing Embedded system is difficult and expensive due to issues such as interoperability, collaboration, synchronization, timing, and concurrency. Embedded systems often require rigorous testing due to the mission-critical nature of their applications. A tester often needs to spend significant time in developing lengthy testing code to ensure that the System Under Test is fully tested for mentioned custom built scale down model. This paper proposes an Extensible Design Patterns based Object-Oriented framework to test Embedded systems by using Scenario Modeling. However, few guidelines are available on to effectively test the software developed with design patterns. This paper first discusses the issues in testing applications developed with design patterns using an object-oriented framework. Two kinds of design patterns are available, extensible and static patterns, and this paper focuses on testing applications using extensible design patterns. This paper then presents a technique, Message Framework Sequence Specifications (MfSS)for generating scenario templates that can be used to generate test cases to test applications developed using extensible design patterns with an Object-Oriented Framework. Finally, this paper uses the MfSS technique to test a Mobile Phone System Framework as an example.
