SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill tackles the issue of superficial tests that only cover happy paths, missing real bugs and edge cases that cause production failures.

Core Features & Use Cases

  • Systematic Analysis: Automatically detects test frameworks, maps input spaces, and identifies key behaviors without user input.
  • Deep Assertions: Writes tests that verify exact values, error types, and side effects, not just existence.
  • Use Case: For a function handling user registration, it generates tests covering valid inputs, invalid emails, duplicate users, and database saves to ensure robustness.

Quick Start

Generate thorough tests for the login function in auth.js, including error cases for invalid credentials.

FAQPage Schema
How do I generate unit tests that catch real bugs instead of just covering happy paths?

To generate bug-hunting unit tests, you need systematic input space analysis and deep assertions that verify exact values, error types, and side effects rather than just checking for existence. This ensures tests catch real bugs and edge cases.

Can I automatically generate integration tests for functions across different programming languages?

Yes, automated test generation can apply to integration testing of functions, modules, or files across languages like JavaScript, Python, and Go. It requires framework detection and code contract extraction to produce reliable, executable tests.

What is the best way to write test assertions that verify side effects and error types?

The best way to write deep test assertions is to extract code contracts and verify exact values, specific error types, and side effects during execution. This goes beyond superficial testing to ensure robustness against invalid inputs and duplicates.

Does automated test generation work with existing test frameworks in my codebase?

Automated test generation works with existing test frameworks by automatically detecting the framework you use. It then maps input spaces and generates executable tests that run through your framework for reliable outcomes.

Why do my current tests miss production failures and edge cases?

Your tests miss production failures because they likely only cover happy paths and superficial assertions. Without systematic input space analysis to identify edge cases like invalid emails or duplicate users, tests fail to catch real bugs.

How do I test a user registration function for invalid inputs and database save errors?

To test a user registration function, generate tests covering valid inputs, invalid emails, duplicate users, and database saves. This systematic approach verifies exact values and side effects to ensure the function handles errors robustly.
