SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Test-driven development helps teams reduce defects by forcing a failing test before coding, ensuring feature correctness from the start.

Core Features & Use Cases

  • Enforces a RED-GREEN-REFACTOR workflow to guide implementation, debugging, and safe refactoring.
  • Promotes test-first thinking across feature and bugfix work, improving maintainability and confidence.
  • Works with common Python testing frameworks (e.g., pytest) to express behavior through tests before code.

Quick Start

Write a failing test for a new feature, then implement the minimal code to make it pass.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How does test-driven development improve software reliability?▼

Test-driven development improves software reliability by enforcing a failing test before coding, ensuring feature correctness and reducing defects from the start.

How do I apply a red-green-refactor workflow to my Python features?▼

To apply red-green-refactor, write a failing test for a new feature, implement the minimal code to pass it, and then safely refactor while maintaining test confidence.

Can I use pytest for test-first development on bugfixes?▼

Yes, you can use pytest for test-first development on bugfixes by writing a failing test that reproduces the bug, then producing production-ready code that passes the test.

What is the best way to start test-driven development on a new feature?▼

The best way to start test-driven development is to write a failing test that expresses the desired behavior, then implement the minimal production code required to make that test pass.

Does test-driven development work for both feature implementation and debugging?▼

Yes, test-driven development works for both feature implementation and debugging by promoting test-first thinking across work, guiding implementation and safe refactoring through strict red-green-refactor cycles.
