Smart contracts often fail in edge cases, under fuzzed inputs, or when interacting with live protocols; this Skill helps teams design tests that catch integration bugs, economic failures, and regressions before deployment. It shifts testing focus from trivial getters to failure modes, invariants, and real-world interactions that can lose funds.
Run Foundry tests with fuzzing and a mainnet fork to validate contract behavior against live protocols.

To test smart contracts for edge cases and integration bugs, apply unit tests, fuzzing, and invariant testing to validate failure modes, access-control flows, and economic invariants before deployment.
Running Foundry tests against forked mainnet state allows you to validate smart contract integrations with deployed DeFi protocols like Uniswap and Aave, catching live interaction bugs before deployment.
Invariant testing detects property violations by implementing handlers to verify contract invariants across thousands of randomized call sequences, exposing economic failures and logic bugs that standard tests miss.
Yes, you can use fuzz testing to find numeric and input-driven bugs by bounding inputs and increasing fuzz runs to systematically expose edge cases in token logic and vault accounting.
Yes, Foundry testing supports precise revert and event assertions, satisfying requirements for robust test suites that verify exact failure modes and contract interactions across DeFi protocols.
Validating AMM invariants and vault accounting logic is best achieved through invariant testing with handlers, ensuring properties hold across randomized call sequences and detecting economic failures before deployment.
