What is fuzz testing? What are invariant tests? We introduce how to use these tools in Web3 & Solidity and explain why they are essential, especially for security. Every project should have stateful fuzz tests moving forward, and auditors can use understanding invariants to find critical bugs before code is deployed. — Shout-out to Trail of Bits and Horsefacts for all the fuzzing content. Introduction
