SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Test-driven development helps ensure code correctness by forcing a failing test before implementation, reducing defects and regressions.

Core Features & Use Cases

Enforces Red-Green-Refactor workflow across feature development, bug fixes, and refactors.
Promotes writing tests before production code, capturing expected behavior and edge cases.
Improves maintainability by providing an executable specification that guides refactoring.

Quick Start

Explain and demonstrate the Red-Green-Refactor cycle by starting with a failing test and implementing the minimum code to pass.

FAQPage Schema

How does test-driven development prevent software regressions?▼

Test-driven development prevents regressions by requiring a failing test before any production code is written, ensuring correct behavior and capturing edge cases as executable specifications throughout the software project.

What is the Red-Green-Refactor cycle for writing tests?▼

The Red-Green-Refactor cycle starts with a failing test, implements the minimum production code to pass it, and then refactors the code while maintaining test coverage for reliable software.

How do I use TDD when fixing bugs or refactoring code?▼

Use TDD for bug fixes and refactoring by writing a failing test that captures the expected behavior, then implementing the minimal code changes to make the test pass and ensure regression safety.

Does test-driven development require specific testing frameworks?▼

Test-driven development does not require specific frameworks, as it focuses on the test-first discipline applicable across software projects to enforce the Red-Green-Refactor workflow regardless of the environment.

When should I not use test-first development for feature development?▼

Test-first development might be less suitable for exploratory prototyping where expected behavior is undefined, as it requires capturing expected behavior and edge cases through tests before implementation.
