Tavor
A generic fuzzing and delta-debugging framework for generating and reducing structured data using an EBNF-like notation.
What is Tavor?
Tavor is a framework for implementing and using fuzzing and delta-debugging techniques without writing source code. It uses an EBNF-like notation to define file formats, protocols, and structured data, enabling automated test data generation and failure isolation. The framework decouples algorithms from data formats to support both research and practical testing applications.
Software testers, security researchers, and developers who need to generate test data for complex structured formats like XML, protocols, or custom file formats. It's also suited for researchers exploring new fuzzing or delta-debugging methods who want to avoid reimplementing core algorithms.
Developers choose Tavor because it provides a universal, model-based foundation for fuzzing and delta-debugging without requiring manual code for each data format. Its declarative format definition and extensible architecture allow for custom tokens, strategies, and filters, making it adaptable to specialized testing scenarios.
