Final answer:
Control flow based testing is a traditional form of black-box testing where test cases are designed to cover different paths through the software code.
Step-by-step explanation:
Control flow based testing is a traditional form of <strong>black-box testing</strong>. Black-box testing is a software testing technique where the internal structure of the system being tested is not known or considered. It focuses on testing the functionality and behavior of the system based on the input and output.
In control flow based testing, test cases are designed to cover different paths through the software code. The goal is to ensure that all logical conditions and branches of the code are tested.
