Reverse Gherkin with AI: Visualizing Specifications from Existing Code

This article discusses the challenge of documenting existing systems without formal specifications. The author highlights the common problem of code functioning without clear specifications, leading to inconsistent interpretations, especially regarding edge cases, permissions, and duplicate processing. They focus on a "point exchange" feature with complex constraints and external dependencies. The core idea is to use AI to generate Gherkin-style specifications from the existing code, effectively reverse-engineering the specifications. This approach aims to create human-readable documentation and improve understanding of the system's behavior without requiring a complete rewrite or manual specification creation.
