SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

TDD provides a disciplined approach to software development by writing tests before code, which reduces defects and improves design.

Core Features & Use Cases

RED-GREEN-REFACTOR workflow to guide feature development and ensure incremental quality.
AAA pattern: Arrange, Act, Assert for clear, maintainable tests.
Use cases include new feature development, bug fixes, and complex logic where tests inform design.

Quick Start

Begin by identifying a small feature, write a failing test, then implement code to pass and refactor as needed.

FAQPage Schema

What is the test-driven development workflow for shipping reliable software?▼

The test-driven development workflow follows a RED-GREEN-REFACTOR cycle: write a failing test, implement code to pass it, then refactor for maintainability. This disciplined approach reduces defects and improves software design incrementally.

How do I apply the AAA testing pattern when writing tests before code?▼

Apply the AAA pattern by structuring tests into Arrange, Act, and Assert phases. Arrange sets up necessary preconditions and inputs, Act executes the behavior under test, and Assert verifies the actual output against expected results.

How do I start using TDD for new feature development and bug fixes?▼

Start TDD by identifying a small feature or bug scenario, writing a single failing test that defines the desired behavior, implementing the minimal code required to pass that test, and refactoring the logic while maintaining test coverage.

When should I use test-driven development for complex logic?▼

Use test-driven development for complex logic where tests inform design, ensuring verifiable and maintainable code. It is highly effective for new feature development and bug fixes where incremental quality and clear behavioral specifications are required.

Does test-driven development work for agile teams building maintainable software?▼

Test-driven development fits agile teams by promoting maintainable, verifiable code through incremental cycles. The RED-GREEN-REFACTOR flow integrates seamlessly into agile sprints, guiding feature development and ensuring continuous quality assurance.
