Based on the study on Web-based systems

this paper presents a systematic testing framework for Web based systems.And focused on test modeling of business logic layers of Web based sy stems

a EJB test model

one kind of platform specific test models(PSTM) according to model driven testing(MDT)

is defined

as well as the approach of its model recovery and model checking are provided.The test modeling deals with the static structures and dynamic behaviors of EJB from the component level and describes a mechanism of code failure detection based on its model checking

which will provide a good support for test cases and test data generation.
