SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This practice guides engineers to always start with a failing test, preventing untested features from entering production.

Core Features & Use Cases

Test-First Workflow: define the expected behavior with a failing test, then implement the minimal code to pass.
Red-Green-Refactor Cycle: iteratively run tests, confirm failures, pass, and clean up code without changing behavior.
Quality & Guidance: provides clear naming, coverage guidance, and refactoring discipline to reduce regressions.

Quick Start

Define a failing test for the new feature, run the tests to see the failure, implement the minimal code to pass, and refactor while keeping tests green.

FAQPage Schema

How do I enforce a test-driven development workflow for new features?▼

Test-driven development is enforced by defining a failing test, confirming the red failure, implementing minimal code to pass, and refactoring while keeping tests green. This prevents untested features from entering production.

What is the red-green-refactor cycle and how does it improve code quality?▼

The red-green-refactor cycle is a test-first workflow where you write a failing test, implement minimal code to pass it, and clean up the code without changing behavior. This reduces regressions and improves overall code quality.

How do I start writing tests before production code for a bug fix?▼

To start writing tests before production code for a bug fix, define a failing test that captures the expected behavior, run the tests to confirm the failure, and then implement the minimal code required to make the test pass.

Can I use test-first development for refactoring existing software projects?▼

Yes, test-first development applies to refactoring across software projects. You ensure testing precedes production code changes and use green tests to support the refactoring process without altering the software's behavior.

Why does writing real tests before implementation prevent regressions?▼

Writing real tests before implementation prevents regressions by validating the red failure first, ensuring only minimal code is added to pass, and maintaining green tests during refactoring to reduce unexpected behavioral changes.

What's the best way to maintain testing discipline during feature implementation?▼

The best way to maintain testing discipline is to follow a strict red-green-refactor cycle, which provides clear naming, coverage guidance, and refactoring rules to ensure every feature is implemented with confidence.
