Fuzzing your GUI for property perfection with Bombadil

The Antithesis platform uses random fuzzing to check whether complex systems keep their property guarantees in all kinds of conditions — but you can fuzz a frontend on your computer with an open-source toolset, Bombadil.

Bombadil sends random inputs to web apps and terminal UIs with its own fuzzer, checking results against built-in properties like "don't leak resources" and custom ones verifying your business logic. Plus, you can deploy Bombadil into Antithesis to leverage its input generation with parallel search powers.

Key takeaways

In this 45-minute session, Antithesis Solutions Engineer Adrian Hatch will demonstrate Bombadil and walk through:

• How to get your own web app under test in just a few minutes
• Best practices for defining your own properties specific to your application, translating business logic and application requirements into a property spec
• How to take Bombadil into the deterministic multiverse to find an extraordinarily rare state in a web app: a win discovered with random actions in the tile-sliding game 2048
