Abstract: Testing Web software faces great challenges. Starting from constructing the PFD(Page Flow Diagram) for Web software, this work proposed a test path generation approach,which was illustrated by the SWI_S(Simple Web Login System) as an example and presented an effective Web testing model for Web software testing. This method provides a meaningful basis for page flow testing technology.

Key words: Web software, Page flow diagram, Page test tree, Lest path, Web test model
