WebA data flow diagram (DFD) maps out the flow of information for any process or system. It uses defined symbols like rectangles, circles and arrows, plus short text labels, to show data inputs, outputs, storage points and the routes between each destination. Data flowcharts can range from simple, even hand-drawn process overviews, to in-depth ... WebMar 25, 2024 · Answer: Both data flow testing and control flow testing use control flow graphs. The only difference is that in control flow testing, we focus on the paths generated from the code, while in data flow testing, we focus on the data values, their definition, and usage within the paths identified within a program.
