SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Inefficient, brittle, or poorly focused tests slow down development, provide a false sense of security, and fail to catch critical bugs, leading to unstable software.

Core Features & Use Cases

  • Strategic Testing: Focus on writing minimal, strategic tests for core user flows, critical paths, and primary workflows, rather than over-testing trivial functionality.
  • Behavior Over Implementation: Design tests to verify what the code does (its observable behavior and outcomes) rather than how it does it (internal implementation details), reducing test brittleness during refactoring.
  • Fast & Isolated Tests: Mock external dependencies (databases, APIs, file systems) to ensure unit tests execute in milliseconds, promoting frequent execution and reliable results.

Quick Start

Write a unit test for the loginUser function, focusing on its behavior for successful login and invalid credentials, mocking any external authentication service.
