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. WebStep 4: Derive test data so that those test paths can be executed Software Testing and Maintenance 4 Graph Models Control flow graph: Captures information about how the control is transferred in a program. Data flow graph: Augments a CFG with data flow information Dependency graph: Captures the data/control
