Test-first feature development using a Red-Green-Refactor cycle starts by writing a failing test, creating a minimal implementation to pass it, and then refactoring the code. This structured approach reduces regression risk and removes design guesswork during feature work.

A minimal Green implementation in test-driven development is the simplest code required to make a failing test pass. After achieving a passing state, you then perform focused refactoring to improve code quality while maintaining regression safety.

Yes, you can use test-driven development for bug fixes and refactoring existing code. The Red-Green-Refactor workflow applies to these scenarios by establishing a regression safety net through tests before altering the logic.

Test-driven development with pytest works effectively for collaborative software teams. It provides clear guidance for teammates by enforcing phase-based testing workflows and creating a regression safety net that supports coordinated feature development.

Test-first discipline reduces regression risk by ensuring every feature implementation is guarded by a pre-written test. This creates a continuous regression safety net that catches errors immediately during the Red-Green-Refactor cycle.

The Red-Green-Refactor cycle may face limitations with large feature work when initial design guesswork is high. Breaking features into smaller, testable increments is necessary to maintain the cycle's effectiveness and ensure minimal Green implementations remain achievable.
