Comprehensive Automated Unit Testing

Writing unit tests is often the most time-consuming part of the development cycle. This skill automates the entire process by analyzing your source code and generating high-quality, framework-idiomatic tests. It doesn't just write "happy path" assertions; it deeply analyzes function signatures and logic to identify edge cases, boundary values, and potential error states that you might have missed.

What it does

• Smart Framework Detection: Automatically identifies your project's testing stack (Jest, Vitest, Pytest, Go testing, or JUnit) by scanning configuration files like package.json or Cargo.toml.
• Context-Aware Generation: Parses your TypeScript, JavaScript, Python, Go, or Rust files to extract exports, classes, and functions.
• Edge Case Analysis: Generates specific test cases for null/undefined inputs, empty strings, maximum boundaries, and async rejections.
• Zero-Config Mocking: Detects external dependencies and sets up framework-specific mocks for HTTP, DB, and filesystem calls.

Why use this skill?

Unlike basic AI prompting, this skill follows a structured multi-step engineering process. It ensures imports are correct, prevents syntax errors, and places files according to project-specific naming conventions (e.g., *.test.ts vs test_*.py). It saves developers hours of boilerplate work while increasing code coverage and reliability without requiring manual intervention.
