| Along with the technical fast development of computer, the computer's hardware performance is more and more high, and the homologous softwareis then more and more huge, more and more complicated, the process-oriented software development technique traditionally has already can't satisfy the request of the efficiency and making use of the resources well in the software development process. For the sake of improving the credibility of software and the efficiency of software developing,object-oriented and the component-based techniques are getting the extensive application, and having become the main technical of software development currently. The application of component-based technical leads to the concept of encapsulation, reuse, and otherwise. These have consumedly raised the efficiency of software development, lowered the cost of the software development. But they also increased the risk of the software credibility and safety. The component which is trustless or insecure usually becomes the most weak chainin the software system, the chain's split will cause breakup of the whole system. Therefore, the credibility and safeties of the component are the foundation of system credibility and safety.How to raise the credibility and safety of the component?Certainly this is firstly the task in the stage of component design and development;But because of the special of the software development, the software flaws can't avoid, so it is important that we carry out the software test actively and availably in software develop process.The software test techniques are complicated, there have the analytical according to the program source code and according to the procedure specification, also according to the states of the program execution, and have formed some advanced theories and mode. The component-based test is a new kind of software test techniques along with the appearance of component-based the software development technical , it has a lot of same... |
