Mocking framework dependencies in tests can lead to brittle, high-maintenance code that suffers from integration issues and upgrade friction. Instead, developers should create thin adapters for external libraries, use real implementations in integration tests, and rely on official testing utilities to ensure reliability and maintainability. By adhering to the principle of not mocking what you don't own, test suites can remain elegant and effective over time.

The article discusses the integration of three significant frameworks—3SF, EPBS, and FOCIL—with a focus on enhancing the efficiency and performance of decentralized systems. It highlights the potential improvements in scalability and resource management that can be achieved through this integration, paving the way for more robust decentralized applications.
