Quite possibly, nothing in web3 is more critical — and difficult to do well — than smart contract testing. For individual developers and small teams, the requisite testing tools are often too expensive and hard to use. Fortunately, a new breed of testing techniques is emerging, ones that are both affordable and accessible.
In my previous article, I talked about one of the most popular techniques: fuzzing. Fuzzing is a dynamic testing technique capable of identifying errors and vulnerabilities that standard tests don’t typically identify. I also talked about how one of the most powerful fuzzing tools — Diligence Fuzzing — just released support for one of the most powerful development frameworks: Foundry. This combination complements your manual audits by providing new vulnerability detection techniques that you can use to avoid costly contract rewrites.
