testability

What problem does it solve?

This skill helps teams design software that is easy to verify, enabling faster feedback, safer refactors, and more reliable releases.

Core Features & Use Cases

• Testing pyramid guidance: define and implement unit, integration, staging, and UI tests from the start.
• Dependency injection patterns: structure code to allow easy mocking and isolation of components.
• Local-first testing setup: strategies for fast feedback cycles with lightweight test data and fixtures.
• API exposure for testing: patterns to surface verifiable interfaces without leaking internals.

Quick Start

Start by identifying a feature and drafting unit tests for pure logic, then introduce mocks for external boundaries and add an integration test for the core workflow.
