About This Skill
What it does
This skill enables AI agents to generate test cases using Test-Driven Development (TDD) principles. It creates unit tests before implementing code, ensuring that developers write clean, maintainable code by defining expected behavior upfront.
When to use it
- Writing new functionality and want to ensure robust testing from the start
- Refactoring existing code to improve quality while maintaining coverage
- Teaching TDD practices to junior developers or teams unfamiliar with the methodology
Key capabilities
- Generates unit tests based on function specifications
- Follows TDD workflow: write test first, then implement code
- Supports multiple programming languages
Example prompts
- "Write a unit test for a function that calculates the sum of two numbers."
- "Generate a TDD test suite for a class that handles user authentication."
- "Create tests for a new API endpoint using the TDD approach."
Tips & gotchas
- Ensure your codebase has proper setup for running generated tests (e.g., testing frameworks like Jest or PyTest).
- Generated tests may require manual adjustments to match specific project conventions or edge cases.
