SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Establishes and enforces a disciplined TDD workflow for Rust projects, ensuring tests drive development and reduce regressions by codifying the Red-Green-Refactor cycle.

Core Features & Use Cases

  • Red: write a failing test to observe failure with cargo test.
  • Green: implement the minimal code to make the test pass, then run cargo test to confirm.
  • Refactor: improve structure while preserving behavior, keeping tests green.
  • Use Case: apply to Rust projects to instill a repeatable, test-driven design process.

Quick Start

Begin by writing a failing test, then implement the minimal code to pass, and finally refactor while all tests stay green.

FAQPage Schema
How do I implement test-driven development in Rust?

Test-driven development in Rust follows the Red-Green-Refactor cycle: write a failing test with cargo test, implement minimal code to pass, then refactor while keeping tests green.

What is the Red-Green-Refactor cycle in Rust?

The Red-Green-Refactor cycle is a disciplined TDD workflow: Red writes a failing test observed with cargo test, Green implements minimal code to pass, and Refactor improves structure while preserving behavior.

How do I start a TDD workflow using cargo test?

Begin a TDD workflow by writing a failing test to observe the failure with cargo test, implement the minimal code required to make it pass, and finally refactor while ensuring all tests stay green.

Does this test-driven development workflow require any specific Rust dependencies?

No specific dependencies are required to apply this test-driven development workflow; it relies solely on standard Rust development tasks and cargo test verification for the Red-Green-Refactor cycles.

When should I use a test-driven design process for Rust projects?

Use a test-driven design process for Rust projects to improve code quality and reduce regressions by codifying the Red-Green-Refactor cycle, ensuring tests consistently drive development.
