Test-Driven Development methodology and red-green-refactor workflow (formerly test-tdd). This skill should be used when practicing TDD, writing tests first, designing tests before implementation, or reviewing test-first approaches. Triggers on "write tests first", "test before code", "red green refactor", "test driven development". This skill does NOT cover Vitest framework specifics (use vitest skill) or API mocking with MSW (use msw skill).
Expert guidance for writing fast, maintainable Minitest tests in Rails applications. Use when writing tests, converting from RSpec, debugging test failures, improving test performance, or following testing best practices. Covers model tests, policy tests, request tests, system tests, fixtures, and TDD workflows.
Apply Test-Driven Development workflow for new features and bugfixes.
This skill should be used when a developer is ready to implement a GitHub Task issue and needs to read the full spec hierarchy (Task + Feature + Epic), explore the codebase, produce a concrete Technical Approach with real file paths, and drive TDD implementation against Gherkin scenarios. Triggers on phrases like "implement task
