SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill helps teams deliver reliable software by enforcing a test-first approach that reduces bugs and rework.

Core Features & Use Cases

  • Red-Green-Refactor cycle: structure development into failing tests, minimal implementation, and cleanup.
  • Test design-first: guides writing tests before feature code to clarify requirements.
  • Quality assurance workflow: supports continuous feedback and safer refactoring across projects.

Quick Start

Start by writing a failing test for a new feature, run the test suite to confirm failure, implement the minimal code to pass the test, run tests again to confirm green, then refactor while keeping all tests passing. Add additional tests to cover edge cases and future enhancements.

FAQPage Schema
How do I automate the red-green-refactor cycle in Python?

Automate the red-green-refactor cycle by writing a failing pytest first, implementing minimal Python code to pass it, and refactoring while keeping the test suite green. This enforces a test-first approach to reduce bugs and rework.

What is test-driven development and how does it guide feature implementation?

Test-driven development structures feature implementation by designing tests first to clarify requirements, writing minimal code to satisfy them, and refactoring safely. This enforces a continuous feedback workflow for reliable software delivery.

Do I need pytest to run test-driven development for my project?

Yes, you need pytest and Python to run this test-driven development workflow. The process requires a minimal project structure to define tests, run them using pytest, and track coverage throughout the development cycle.

How do I start writing tests before feature code to clarify requirements?

Start writing tests before feature code by creating a failing test for a new feature, confirming the failure by running the test suite, implementing minimal code to pass, and adding edge case tests to guide future enhancements.

When should I use a test-first approach for software engineering?

Use a test-first approach when delivering reliable software that requires safer refactoring and reduced rework. It supports continuous feedback across projects by enforcing quality assurance through structured test design before implementation.
