SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Exhaustive edge-case discovery that systematically hunts production break points in code and reports only the unhandled, high-risk scenarios, while assuming existing happy-path tests.

Core Features & Use Cases

  • Systematic edge-case hunting across code paths, including nulls, timeouts, race conditions, and boundary values.
  • Generates a structured edge-case report with risk scores and ready-to-use test code.
  • Auto-detects language and outputs runnable tests in the project's test framework.

Quick Start

Provide a target directory or files and run the edge-case-hunter tool to generate a report of high-risk edge cases.

FAQPage Schema
How do I find unhandled edge cases in my code?▼

Edge case hunting systematically explores branching paths, boundary conditions, nulls, timeouts, and race conditions in your code to surface only the unhandled, high-risk scenarios that happy-path testing misses.

How do I generate tests for boundary conditions and failure scenarios?▼

Generating tests for boundary conditions involves providing accessible target code like diffs or small modules, which then produces a structured edge-case report with risk scores and ready-to-use test code.

Can I use edge case analysis on diffs or small modules in any language?▼

Edge case analysis works on diffs, code samples, or small modules in any programming language, auto-detecting the language to produce a structured edge-case report and runnable test snippets.

What's the best way to review code for race conditions and null handling?▼

Reviewing code for race conditions and null handling requires systematically exploring code paths and data flow to identify these specific failure scenarios, producing a structured report with risk scores and test snippets.

Does this edge case hunting approach assume existing happy-path tests?▼

This edge case hunting approach assumes existing happy-path tests are in place, focusing its analysis exclusively on discovering and ranking unhandled production break points like nulls, timeouts, and race conditions.
