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.

What are Fuzz tests? What are invariant tests? What are they for?

The fuzz/invariant test suite is one we at Cyfrin use to find high-severity issues quickly before we jump into the manual review!

This is the new FLOOR for security in Web3. Please understand your invariants and write fuzz tests for them!
