SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It solves the problem of adding or improving tests that fail for the wrong reasons, produce low confidence signal, and slow down development.

Core Features & Use Cases

  • Strategy-first testing: Designs a testing approach by deciding what needs unit, integration, or end-to-end coverage.
  • Seam-driven implementation: Picks the highest seam that still yields deterministic, behavior-based feedback (API/Service/Domain).
  • High-signal verification: Ensures tests fail only when externally observable behavior changes, while keeping feedback fast and avoiding unnecessary mocking of internal modules.

Quick Start

Provide your feature description, relevant public APIs, and desired outcomes, and ask for a test strategy plus concrete test code that validates behavior with fast, deterministic integration tests.

FAQPage Schema
What is a behavior-focused testing strategy?▼

A behavior-focused testing strategy prioritizes verifying externally observable behavior over internal implementation details, ensuring tests fail only when actual functionality breaks rather than during internal refactoring.

How do I write integration tests that provide fast feedback?▼

To write integration tests with fast feedback, select the highest deterministic seam like API or service boundaries, avoid mocking internal modules, and optimize the test suite execution speed to accelerate development.

Why do my tests fail for the wrong reasons during refactors?▼

Tests fail during refactors because they rely on internal implementation details rather than public APIs. Designing high-signal, behavior-driven tests prevents false failures and maintains confidence during code changes.

When should I use thin fakes instead of mocking internal modules?▼

Use thin fakes for external services to maintain deterministic test seams, while avoiding mocking internal modules entirely. This approach prevents unreliable, low-signal test suites and maximizes test confidence.

How do I decide between unit and integration test coverage?▼

Decide between unit and integration coverage by implementing a strategy-first approach that evaluates what needs testing, then picks the highest seam that yields deterministic, behavior-based feedback for each module.
