Show HN: FizzBee – Formal Model based autonomous testing

Most developers agree testing is important. At the same time, most developers don’t enjoy writing tests. With AI generating code faster than ever, testing is becoming even more crucial. But even AI-generated tests need review and maintenance, which makes them another burden.

I'm introducing another form of autonomous testing - "model-based testing". Instead of writing test cases, you describe expected behavior in a Python-like specification language.

The FizzBee model can be: - Verified exhaustively for design bugs (like formal methods). - Mapped to your actual system, automatically generating the tests.

This gives you:

- No hand-crafted test cases - Automatic testing of concurrent as well as sequential behavior - No cascading test rewrites when behavior changes - No cluttering the SUT with tracing code

With FizzBee, you get both design validation (like in formal methods) and automatic test generation, saving time and effort.

Currently, only Go is supported. Java and Rust are next and would love to hear which language you’d want supported next.

I’d love your feedback!
