Vitest testing framework patterns for test setup, async testing, mocking with vi.*, snapshots, and test performance (formerly test-vitest). This skill should be used when writing or debugging Vitest tests. This skill does NOT cover TDD methodology (use test-tdd skill), API mocking with MSW (use test-msw skill), or Jest-specific APIs.
Vitest testing framework expert for Vite integration, Jest migration, browser mode testing, and performance optimization
Enhances Vitest with Midscene for AI-powered UI testing across Web (Playwright), Android (ADB), and iOS (WDA). Scaffolds new projects, converts existing projects, and creates/updates/debugs/runs E2E tests using natural-language UI interactions. Triggers: write test, add test, create test, update test, fix test, debug test, run test, e2e test, midscene test, new project, convert project, init project, 写测试, 加测试, 创建测试, 更新测试, 修复测试, 调试测试, 运行测试, 新建工程, 转化工程.
Write tests using Vitest and React Testing Library. Use when creating unit tests, component tests, integration tests, or mocking dependencies. Activates for test file creation, mock patterns, coverage, and testing best practices.
Use when vitest performance optimization including fast execution, watch mode, and parallelization strategies.
Vitest 3 Features skill

Triggers on Jest, Vitest, describe/it/expect, mocking, vi.fn, jest.fn, snapshot testing, test coverage, and any task requiring JavaScript/TypeScript unit testing.
Vitest unit testing patterns with React Testing Library. Trigger: When writing unit tests for React components, hooks, or utilities.
Provides comprehensive guidance for Vitest testing framework including fast test execution, Vite integration, component testing, mocking, and configuration. Use when the user asks about Vitest, needs to write fast unit tests, test Vue/React components, or configure Vitest with Vite projects.
Modern JavaScript/TypeScript testing with Vitest including mocking and coverage.
Vitest testing framework patterns and best practices. Use when writing unit tests, integration tests, configuring vitest.config, mocking with vi.mock/vi.fn, using snapshots, or setting up test coverage. Triggers on describe, it, expect, vi.mock, vi.fn, beforeEach, afterEach, vitest.
Vitest testing framework for unit, component, and integration tests. Covers test structure (describe/it/test.each), assertions with expect, lifecycle hooks, mocking (vi.fn/vi.mock/vi.spyOn), React Testing Library patterns, hook testing with renderHook, user-event interactions, async utilities, configuration, workspace setup, coverage, and advanced patterns like in-source testing and concurrent execution. Use when writing unit tests, component tests, integration tests, or testing React hooks. Use for test configuration, mocking modules, testing async behavior, snapshot testing, or setting up test coverage.
