TDD(テスト駆動開発)で実装します。赤-緑-リファクタリングのサイクルに従って開発を進めます。
Live UI development workflow using tmux panes + Playwright for visual feedback. Start dev server in one pane, use Playwright for testing, screenshots, and mobile/responsive verification in real-time.
Local Python-based browser automation toolkit using Playwright. Provides command-line tools for navigating, interacting with, and testing web applications. Supports clicking, typing, hovering, screenshots, cont...
Apply testing patterns like AAA (Arrange-Act-Assert), mocking, fixtures, and parameterization for maintainable test suites
Test with NVDA, JAWS, VoiceOver, validate ARIA attributes, and ensure semantic HTML
Measure and improve test coverage by identifying untested code paths and prioritizing high-risk areas for testing
Design and execute load tests to validate performance under stress, identify scalability limits, and ensure SLA compliance
Apply testing philosophy: test behavior not implementation, minimize mocks, AAA structure, coverage for confidence not percentage. Use when writing tests, reviewing test quality, discussing TDD, or evaluating t...
Apply code quality standards for testing, coverage, CI/CD, and automation: Vitest, coverage philosophy, git hooks, GitHub Actions, quality gates. Use when setting up testing, configuring CI, discussing quality...
Testing Library for React - render, screen, userEvent, waitFor. Use when writing tests for React components with Vitest or Jest.
Test SwiftUI apps with XCTest, UI tests, snapshot testing, and async testing. Use when writing unit tests for ViewModels, creating UI automation tests, implementing snapshot tests, or testing async code.
Write tests with Pest/PHPUnit, feature tests, unit tests, mocking, and factories. Use when testing controllers, services, models, or implementing TDD.
Generate and run tests for code. Use when creating unit tests, integration tests, or running test suites. Includes Context7 test framework documentation lookup.
Complete testing methodology - TDD, progression tracking, regression prevention, and test patterns
Principles and patterns for writing effective React tests with Jest and React Testing Library. Use during implementation for test structure guidance, choosing test patterns, and deciding testing strategies. Emp...
Use when creating leaf types, after refactoring, during implementation, or when testing advice is needed. Automatically invoked to write tests for new types, or use as testing expert advisor. Covers unit, integ...
This skill should be used when the user needs to 'debug web applications', 'test UI interactions', 'capture screenshots or network requests', 'test desktop automation', or needs to select between testing tools....
This skill should be used when the user asks to "implement using TDD", "test-driven development", "RED-GREEN-REFACTOR", or "write failing test first". Enforces test-first approach with RED-GREEN-REFACTOR cycle...
Playwright MCP browser testing. Headless E2E, cross-browser, CI/CD automation.
Test the Nathaniel macOS game. Use when asked to test the macOS version, verify changes work on Mac, run sanity tests on desktop, or when the user says "test macOS", "run on mac", "verify mac build".
Write or update unit (not integration) tests in this repo, use Verify snapshot testing for source generator output, and run/accept snapshots via the provided scripts.
Use when writing unit tests, adopting Swift Testing framework, making tests run faster without simulator, architecting code for testability, testing async code reliably, or migrating from XCTest - covers @Test/...
Use when testing async code with Swift Testing. Covers confirmation for callbacks, @MainActor tests, async/await patterns, timeout control, XCTest migration, parallel test execution.
