Automated Black Box Testing For Embedded Software

With the rapid development of computer hardware technology, the scale and capability of hardware of embedded system has been greatly improved. Accordingly, the complexity and scale of system software and application software of embedded system also grow increasingly. Simultaneously the speciality of embedded system asks for embedded software being more smart and reliable. There is no doubt that the R&D of software plays a more and more important role in R&D of the whole embedded system. The quality of software plays a decisive and reliability of software and shorten the development cycle.Recently, There are already many systematic, integrated and mature White Box test theory, method and tools for embedded system. But when it refers to Black Box test, both the test theory and method is lacking. The current automation test tool ether has limited test scope or is very expensive.This article refers a new pure software-drive method to test embedded system automatically. There is no special hardware requirement, it is easy to execute. With the help of embedded system platform, you only need add fewer stubs in test object. The insert test stub, the debug protocol and the client run on PC can help you complete most of the Black Box test work.According to this method, combine with the implement of automation test in real environment, This article bring out a series of theory about automation test, and resolve many key issues, including organization and management of test case. A tool which is built according to this method has been used in a big project, and it brings big benefit to the project. Facts have proved that the method can actually cover most of the Black Box test.
