The Test Technology Of Software And One Typical Application

From considerations of the features of embedded software。 one solution to the management of embedded software testing based V model improved is presented in this thesis after discussing the general test technology of software. The solution discussed includes process management and methods application. Finally, the engineering applications of the solution are mentioned in this paper.The standardization and the stratification of code and the rationalization of the dependency relations among modules are important factors of software quality. After analyzing module dependencies, test case must be designed for each module in the source file, to achieve some test coverage criteria, and to ensure test adequacy. Unit test can be divided into two processes namely checking the code and executing the test, which detailedly includes scanning the source file, checking the code, analyzing the speciality of module dependencies, generating test cases and finally executing the test.In order to improve the efficiency and the veracity of unit test, it is essential to automate above processes, so to reduce manual work.The invation of the V model improved in this thesis make the test of the embedded software controllable. To covering basic control path, one automated test way is brought forward and the architecture design of the software supporting this way is finished.In addition, some experience is discussed about automated test technique such as using test script and test tools.
