Foundry Fuzz
Open SourceBuilt-in fuzz testing in the Foundry development framework. Write Solidity tests that automatically generate random inputs to find edge cases.
About
Foundry's fuzz testing capabilities are built directly into the forge test command. By adding parameters to Solidity test functions, Foundry automatically generates random inputs to stress-test your contracts. It supports configurable fuzz runs, shrinking of failing inputs, and invariant testing for stateful fuzzing campaigns. Being native to Foundry means zero additional setup for teams already using the framework.
