Data flow graph testing
WebDynamic data flow testing involves identifying program paths from source code based on a class of data flow testing criteria. Data flow testing is generally performed in the following steps : a. Draw a data flow graph … Web•Organized into a Control-Flow graph •nodes: labeled basic blocks of instructions •single-entry, single-exit •i.e., no jumps, branching, or labels inside block •edges: jumps/branches to basic blocks •Dataflow analysis •computing information to answer questions about data flowing through the graph. 5

WebBranch Coverage Testing. Branch coverage technique is used to cover all branches of the control flow graph. It covers all the possible outcomes (true and false) of each condition of decision point at least once. Branch coverage technique is a whitebox testing technique that ensures that every branch of each decision point must be executed.
