WebControl Flow Graphs: o The control flow graph is a graphical representation of a program's control structure. It uses the elements named process blocks, decisions, and junctions. o The flow graph is similar to the earlier flowchart, with which it is not to be confused. WebProgramming language for testing doesn't matter. I desire if the tool can generate data flow graph from given source code program, test requirements, test path, and coverage result in statistic. If anyone know the tool/software, but it doesn't meet my description. Feel free to post a comment. Summary of data flow testing can be found here.
