SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Test-driven development guides teams to write tests before production code, reducing defects and aligning implementation with expected behavior.

Core Features & Use Cases

  • Guided development: Write a failing test first, then implement the minimal code to pass.
  • Risk reduction: Early failure detection and refactoring with confidence.
  • Use Case: For a new feature, start with a failing spec, implement just enough to satisfy the spec, then iterate.

Quick Start

Use the TDD workflow: write a failing test, run tests to see failure, implement minimal code to pass, and refactor while keeping all tests green.

FAQPage Schema
What is test-driven development and how does it improve code quality?▼

Test-driven development is a practice where you write failing unit tests before production code, reducing defects and aligning implementation with expected behavior to improve maintainability.

How do I start writing unit tests using the red-green-refactor workflow?▼

To start writing unit tests using the red-green-refactor workflow, write a failing test first, run it to see the failure, implement minimal code to pass, then refactor while keeping all tests green to ensure continuous validation.

Can I use test-driven development for bug fixes and refactoring existing code?▼

Yes, you can use test-driven development for bug fixes and refactoring existing code. It ensures software changes are guided by failing tests and minimal implementations, allowing you to refactor with confidence while maintaining correctness across features.

What's the best way to reduce software defects when adding new features?▼

The best way to reduce software defects when adding new features is following test-driven development: start with a failing spec, implement just enough code to satisfy the spec, then iterate. This early failure detection ensures correctness and maintainability.

When should I not use test-driven development for software engineering tasks?▼

The metadata does not specify explicit scenarios when you should not use test-driven development. It generally enforces TDD practices across features, bug fixes, and refactors to improve correctness and maintainability without noted limitations.
