Abstract:
Formal methods have been used so much nowadays in development projects in where there is a requirement for the software behavior being as it is expected to be. However, there are few projects that are disposed to invest their money in capable human resources. In this work it is presented a technique developed for making it easier to use formal methods, model checking more precisely, in the concurrent object oriented software development processes. It is defined a behavioral description language that is able to model multi-threaded object oriented programs. Such a language, written together with the source code, in an annotation language format, acts like the abstraction of the program to be verified. Due to its similarity to a programming language, the programmer is who models its own code, not being necessary to have an expert to formal modelling of the system. Besides, also due to its annotation characteristic, it eases the synchronization problem between the model and the modelled system. The described models using the behavioral description language are translated to an existent executable formal language. With this formal model and the specified properties to be checked in hands, the model checking process is done by using a model checker. The developer just stays in direct contact with annotations and returned results from the verification process. The rest of the process occurs in a totally hidden way to the user, in a black box.
