+# E2E Tests
+
+This directory contains end-to-end tests for ZCLAW desktop application.
+
+## Test Strategy
+
+Due to ZCLAW being a Tauri 22.0 desktop application, E2E testing requires special consideration:
+
+### Option 1: Vitest + @testing-library/react (Current)
+- Unit and integration tests use Vitest
+- Component tests use @testing-library/react
+- Already configured and working (312 tests passing)
+
+### Option 2: Playwright for Web UI (Future)
+- Playwright is available in `desktop/node_modules`
+- Can test the React UI layer independently
+- Cannot directly test Tauri native functionality
+
+### Option 3: Tauri Driver (Recommended for Full E2E)
+- Use Tauri's built-in test utilities
+- Requires `tauri-driver` package
+- Can test full application including native functionality
+
+## Current Status
+
+- **Unit Tests**: ✅ 312 tests passing
+- **Integration Tests**: ✅ Store and component integration verified
+- **E2E Tests**: 🚧 Framework setup in progress
+
+## Running Tests
+
+```bash
+# Unit/Integration tests
+pnpm vitest run
+
+# E2E tests (when implemented)
+pnpm test:e2e
+```
