Enhancing Test Coverage: A Framework for Effective Protocol Security
summary
An experimental framework groups concrete test work into three mindsets: hacker mindset, formal verification, and system architect. It claims 100% coverage doesn't prevent hacks, recommends 80–90% coverage plus unit and integration tests, and draws on 250+ audits since 2017. Write tests that assert role-restrictions, call-frequency limits (example: once-per-hour), input bounds (avoid uint256→uint8 overflow), invariants (swap output ≤ contract balance, tracked total ≤ on-chain balance), mock all off-chain services and check upgrade paths; use fuzzing if full formal proofs are infeasible.
