SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Test-Driven Development helps teams build higher-quality software by insisting that tests define the expected behavior before implementation, reducing defects and enabling safer refactors.

Core Features & Use Cases

Test-first workflows: Write failing tests prior to production code to guide design.
Red-Green-Refactor discipline: Use iterative cycles to verify behavior and improve code quality.
Risk reduction: Catch regressions early and clarify requirements before coding.

Quick Start

Start by writing a failing test for the desired behavior, then implement the minimal code to pass it.

FAQPage Schema

How does test-driven development improve software quality?▼

Test-driven development improves software quality by requiring failing tests to define expected behavior before implementation, reducing defects and enabling safer refactoring through iterative cycles.

What is the red-green-refactor cycle in unit testing?▼

The red-green-refactor cycle in unit testing is an iterative workflow where you write a failing test first, implement minimal production code to pass it, then refactor for maintainability.

How do I start writing tests before production code?▼

To start writing tests before production code, define a specific behavior with a failing unit test, then implement only the minimal code required to make that test pass.

Can I apply test-first workflows to integration testing scenarios?▼

Yes, test-first workflows apply to integration testing scenarios, enforcing iterative cycles that verify component interactions and clarify requirements before writing the connecting production code.

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

Test-driven development may not suit exploratory software testing or throwaway prototypes where requirements are highly volatile and writing failing tests upfront adds unnecessary overhead.

Why write failing tests before writing implementation code?▼

Writing failing tests before implementation code clarifies exact requirements and ensures the test actually validates the desired behavior, catching regressions early and guiding design decisions.
