Fuzz testing, or fuzzing, is a technique used to improve the security of software, including smart contracts in Solidity. It involves supplying random or unexpected data as inputs to a system in an attempt to break it and uncover vulnerabilities that manual testing might miss. Fuzzers generate a set of inputs for testing scenarios that may have been missed during unit testing, helping to identify bugs and potential security issues.
