Testing Writing Guidelines

About

This skill implements a strategic and minimalist approach to test writing, directing Claude to focus exclusively on core user flows and critical business logic. It prioritizes creating fast, behavior-focused tests with clear, descriptive names and proper mocking of external dependencies. By deferring tests for edge cases and non-critical utilities until explicitly requested, this skill helps streamline the development process, providing a robust testing foundation for the most important "happy path" functionality without getting bogged down in exhaustive, upfront test creation.
