How to effectively test the application, always use when writing tests
Design and implement visual regression testing for UI changes. Defines screenshot coverage, rendering stabilization, baseline management, and CI integration (e.g., Playwright screenshots, Percy/Chromatic). Use when UI/styling/layout changes need protection against regressions, or when adding screenshot-based tests to a web/WASM/desktop UI.
Use when running tests to validate implementations, collecting test evidence, or debugging failures. Load in TEST state. Covers unit tests (pytest/jest), API tests (curl), browser tests (Claude-in-Chrome), database verification. All results are code-verified, not LLM-judged.
AI-powered E2E testing for any app. Test 8 platforms with natural language — no test code needed.
Use this skill when you need to test or evaluate LangGraph/LangChain agents: writing unit or integration tests, generating test scaffolds, mocking LLM/tool behavior, running trajectory evaluation (match or LLM-as-judge), running LangSmith dataset evaluations, and comparing two agent versions with A/B-style offline analysis. Use it for Python and JavaScript/TypeScript workflows, evaluator design, experiment setup, regression gates, and debugging flaky/incorrect evaluation results.
AI-powered E2E testing for any app — Flutter, React Native, iOS, Android, Electron, Tauri, KMP, .NET MAUI. Test 8 platforms with natural language through MCP. No test code needed. Just describe what to test and the agent sees screenshots, taps elements, enters text, scrolls, and verifies UI state automatically.
Comprehensive testing strategies for Bubbletea v2 applications. Covers unit tests, component tests, golden file testing, async operations, external tool integration, and common testing pitfalls.
Run test suite and report results. Use when user asks to "run tests", "/test", "/testing", "execute tests", or requests running the test suite.
Testing patterns and standards for this codebase, including async effects, fakes vs mocks, and property-based testing.
Write unit and integration tests for Salvo applications using TestClient. Use for testing handlers, middleware, and API endpoints.
Browser automation skill for UI testing via Chrome MCP tools. Use when: (1) QA Agent needs to verify UI visually or test interactions, (2) UI/UX Designer needs to check responsive design or component states, (3) Frontend Dev needs quick visual verification during development, (4) Test Writer needs to document user flows with screenshots/GIFs, (5) Any agent needs to test web interfaces, record demos, or debug UI issues. Capabilities: screenshots, interaction testing, accessibility checks, GIF recording, responsive testing, console/network debugging.
CVE vulnerability testing coordinator that identifies technology stacks, researches known vulnerabilities, and tests applications for exploitable CVEs using public exploits and proof-of-concept code.
