Abstract

OSEK / VDX specifications are European automotive industry in the mid-1990s developed an automotive electronics design specification, which provides the development of embedded computer systems networked together the organic combination of a variety of advanced automotive electronic equipment specification. Currently, there are a lot of companies and research institutions to develop the OSEK operating system. OSEK / VDX standard is described in natural language itself is still in development, possible differences in OSEK / VDX operating system developed by different developers. For Inspection specification consistency of these operating systems, you need to conformance testing. OSEK operating system based on the classification tree constructed test cases, conformance testing specification based on in-depth understanding of the OSEK operating system. The method first extracted from the OSEK operating system specification testing purposes, followed by a classification tree according to the purpose of the test and test cases from a classification tree, then perform these test cases on the OSEK operating system Finally, according to the results of the implementation of the test case to determine operation The system specification compliance. OSEK operating system based on the classification tree consistent approach to both take advantage of the OSEK operating system is only a small amount of functional modules and the characteristics of the API, and also take advantage of the advantages of a structured and systematic method of classification tree, making the the consistency test set constructor easier to grasp and understand. The main work and contributions of this paper can focus on three things: (1) operating system conformance test specification based on the classification tree method specification operating system conformance testing process includes four steps, the first is from the standard extracted for testing purposes, followed according to the standards and testing purposes, the use of the classification tree constructed abstract test case, and then on a specific operating system and execute test cases, and finally the analysis results of the implementation of the test cases. The specification also provides for the representation of each step must strictly abide by, such as the representation of the purpose of the test, the abstract test case. (2) using the classification tree method to construct OSEK operating system consistency test set by in-depth understanding of the OSEK operating system specification, analysis the API execution environments, perform actions and perform classification tree input field; analysis testing purposes, the use of the classification tree tools, classification tree test; abstract test suite by combining a variety of test conditions, the final structure. (3) conformance testing MiniOSEK under MiniOSEK realization characteristics, classification tree method to construct the set of abstract test concrete, then perform these tests in MiniOSEK set, and test results were analyzed. The test results show that, MiniOSEK involved in testing modules through conformance testing.
