Stubs and Drivers are programs used during testing to simulate interactions between components in software systems.
- Stubs: Replace lower-level components called by the module being tested, providing predefined responses.
- Drivers: Act as higher-level components that call the module being tested, simulating user input or external systems.
Together, stubs and drivers facilitate effective unit testing by allowing developers to isolate specific modules and verify their functionality without needing complete system integration at every stage of development.
