Data flow graph testing
WebOverview. Data flow testing is a white box testing technique where the module is tested on the basis that the value of the variable passing is correct. Control flow graphs are used … 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.
