test-driven-development

Test-driven development is a test-first workflow enforcing small, incremental iterations through the red-green-refactor cycle. You write a failing test, implement code to pass it, then refactor. This structured approach reduces bugs and keeps scope tight during software development.

To start test-driven development, request the AI to guide a red-green-refactor cycle for your next feature. You begin by writing a failing test and end with a passing implementation, using explicit opt-in activation to ensure small, validated iterations throughout the process.

Yes, test-driven development provides guardrails to keep scope tight and align with existing project rules. It is applicable to software projects introducing TDD for new features, modules, or components, ensuring structured quality assurance without disrupting current workflows.

You should opt in to test-driven development when you need to reduce bugs through structured, test-first workflows. It is ideal for introducing TDD to new features or components, providing guardrails for small, validated iterations when tests are explicitly requested.

The opt-in test-driven development workflow requires explicit activation and does not apply automatically to all code changes. It is limited to scenarios where TDD is requested, focusing on small, incremental cycles rather than large-scale architectural modifications.
