Final answer:
False. Graph-based testing can be used for systems other than object-oriented systems.
Step-by-step explanation:
False. Graph-based testing methods can be used for systems other than object-oriented systems. Graph-based testing is a technique where test cases are derived and executed based on a model of the system's behavior. This model can be represented using various types of graphs, such as control flow graphs, data flow graphs, and state transition diagrams.
For example, in a control flow graph, nodes represent program statements or actions, and edges represent the flow of control between them. By modeling the system using a graph, testers can generate test cases that exercise different paths or scenarios in the system, helping to uncover potential bugs or issues.
