SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires pytest, and includes scripts (resource) components.

What problem does it solve?

This Skill ensures that you follow the Test-Driven Development (TDD) methodology, leading to more robust and reliable code by enforcing the creation of tests before writing the actual code.

Core Features & Use Cases

  • Enforce TDD Process: Writes tests before the code, promoting code quality and maintainability.
  • Red-Green-Refactor Cycle: Guides through the RED (Write Failing Test), GREEN (Minimal Code), and REFACTOR cycles.
  • Integration with Hermes Agent: Allows running tests and debugging within the Hermes Agent ecosystem.

Quick Start

Use the test-driven-development skill to create a new test for a feature you are implementing.

FAQPage Schema
How do I implement test-driven development for new features and bug fixes?▼

Test-driven development enforces writing failing tests before production code, guiding you through the RED, GREEN, and REFACTOR cycles to promote robust code quality and maintainability across all software development phases.

What is the red-green-refactor cycle in test-first development?▼

The red-green-refactor cycle in test-first development involves writing a failing test (RED), writing minimal code to pass it (GREEN), and refactoring the code while ensuring tests still pass, leading to reliable software behavior.

Can I use pytest for executing test-first development scripts?▼

Yes, pytest is required for executing test-first development scripts, allowing you to run tests and debug code behavior directly within the Hermes Agent ecosystem to ensure your production code meets behavior specifications.

Does test-driven development work for refactoring existing Python code?▼

Test-driven development works for refactoring existing Python code by focusing tests on actual code behavior, ensuring that modifications and bug fixes do not break existing functionality while maintaining high code quality.

What's the best way to ensure code quality when writing tests after production code?▼

To ensure code quality, switch to test-first development by writing tests before the actual code, which enforces a behavior-driven approach and prevents untestable code designs from compromising software maintainability.
