Defines patterns for writing tests, including subsection tests for incremental development and acceptance criteria verification. Use when writing any tests to ensure consistent naming, structure, and coverage patterns.
How to structure applications for optimal testability in Clojure and Clojurescript, along with how to use guardrails and fulcro-spec to do the actual testing. You MUST use this skill when writing Clojure and Clojurescript if fulcro-spec is a dependency.
Use when writing Rails tests - enforces fixtures-only, integration-style controller tests, Current context setup, simple naming, and Minitest syntax
Generate end-to-end tests for the complete Desktop Ethereal application, including UI interactions, system integration, and user workflows. Triggers on E2E testing, Playwright, system testing, or complete application testing requests.
Use to assess non-functional requirements (security, performance, reliability, maintainability) through E2E integration testing patterns.
Run Python tests with pytest and analyze results. Use when the user asks to run tests, check test coverage, or verify Python code functionality.
Generate test scenarios for Fujian Mahjong game logic. Use when you need test cases for win detection, Gold substitution, calling validation, edge cases, or scoring calculations.
Use when writing tests for NestJS + MikroORM with transaction rollback and real DB integration.
Run tests in the actual execution environment, not just where they compile - TDD's "watch it fail" step is meaningless if tests skip or can't run where code will execute
Use when implementing any feature or bugfix, before writing implementation code - write the test first, watch it fail, write minimal code to pass; ensures tests actually verify behavior by requiring failure first
MSW (Mock Service Worker) patterns for testing Umbraco backoffice extensions with mocked APIs
Ejecuta pruebas de testthat para confirmar la generación de 300+ versiones únicas (Fase 3 del workflow).
Tiered testing strategy (UI mock, auth stub, full-stack), fixtures, mocks, and test configuration. Handles test setup, Playwright E2E tests, pytest backend tests, mocking strategies, and CI test configuration. Use when working with tests, test setup, mocking strategies, or CI test configuration, or when user mentions test patterns, auth stub, fixture loaders, Playwright tests, test failures, tiered testing, UI mock, E2E tests, pytest, vitest, or debugging test issues.
Expert guide for Test-Driven Development in FastAPI, focusing on the "Quads" strategy and async testing patterns.
Master iOS testing - XCTest, UI testing, mocking, debugging, performance
This skill should be used when the user asks to "write XCUITest", "create UI tests", "fix flaky tests", "query XCUIElements", "implement Page Object pattern", or mentions XCUITest, UI testing for iOS/macOS apps. Targets experienced iOS developers who want best practices and efficiency improvements.
Write and run JavaScript/TypeScript tests using Vitest or Jest with mocking, component testing, and coverage. Use when writing JS/TS tests, testing Svelte/React components, or setting up test configuration.
This skill should be used when the user asks to "测试用例整理", "测试整理", "organize test cases", "reorganize tests", "consolidate scattered tests", or mentions test cases scattered in business code that need to be moved to proper test directories.
This skill should be used when the user asks about "EARS syntax", "EARS notation", "acceptance criteria format", "SHALL patterns", "formal requirements", "WHEN THE SHALL", or needs guidance on writing testable requirements using EARS (Easy Approach to Requirements Syntax).
Write and run Python tests using pytest with fixtures, mocking, coverage, and the AAA pattern. Use when writing Python tests, creating test files, or setting up pytest configuration.
