What does a control flow graph (CFG) represent in white-box testing?

Question

BlackTom AI · Accepted Answer

When evaluating what a control flow graph (CFG) represents in white-box testing, it's helpful to map the concept to how code executes.
Option 1: 'The timeline of function calls' – This is a partial way to think about execution, but CFGs specifically focus on the flow of control between statements and blocks within the code, not just a chronological list of function calls.
Option 2: 'The data structure of a program' – This describes how data is organized (arrays, trees, objects), which is the realm of data structures, not control flow. CFGs do not depict data layout or types.
Option 3: 'All possible execution paths in the code' – This accurately captures the essence of a CFG: it models the various paths that execution can take through the program, including branches, loops, and branches caused by conditionals. It is exactly what white-box testers analyze to assess coverage and path feasibility.
Option 4: 'How users interact with the UI' – This concerns user interface behavior and event flows, not the internal control flow of program code. CFGs are about program control, not user interaction patterns.
Option 5: 'The layout of the database schema' – This relates to database design and relationships, not to the control flow within software. CFGs do not depict schemas or data storage structures.
In summary, option 3 correctly identifies the CFG as representing all possible execution paths within the code, while the other options describe concepts outside the scope of control flow graphs and white-box testing analysis.
