SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Prove-first enforces a test-first discipline during feature implementation to reduce bugs and rework by ensuring tests fail before any code is written, then minimal code is implemented to pass.

Core Features & Use Cases

  • Enforces writing a failing test before implementation
  • Guides iterative development from red to green
  • Applies to both feature enhancements and bug fixes across software projects

Quick Start

Write a failing test for the chosen feature, then implement the minimal code to make the test pass.

FAQPage Schema
What is test-driven development and how does it reduce bugs during feature implementation?▼

Test-driven development is a process where you write a failing test before implementing code, then build minimal code to pass that test. This enforces test-first discipline to reduce bugs and rework by verifying failures initially.

How do I start writing tests before code for a new software feature?▼

To start writing tests before code, write a failing test for the chosen feature, verify the test fails, implement the minimal code required to make it pass, then commit changes after the test turns green.

Can I apply test-first development to bug fixes as well as feature enhancements?▼

Yes, you can apply test-first development to both feature enhancements and bug fixes across software projects. It guides iterative development from red to green by requiring a failing test before any bugfix code is written.

What is the best way to ensure my code changes are committed only after tests pass?▼

The best way to ensure code changes are committed only after tests pass is to follow a test-first workflow that requires minimal code implementation to turn failing tests green before allowing any commit.

Why do my tests need to fail initially before I write implementation code?▼

Tests need to fail initially to prove the test is actually checking the new behavior and to enforce test-first discipline. Verifying this failure ensures you implement minimal code specifically to pass the test and reduce rework.
