+# Testing Documentation
+
+This project uses **Vitest** for unit/integration tests and **Playwright** for end-to-end testing.
+
+## Quick Start
+
+```bash
+# Run unit tests (watch mode)
+npm test
+
+# Run unit tests with UI
+npm run test:ui
+
+# Run E2E tests
+npm run test:e2e
+
+# Run E2E tests with UI
+npm run test:e2e:ui
+```
+
+## Unit Tests (Vitest)
+
+Unit tests are located in `__tests__/` directory and test individual functions, hooks, and components in isolation.
+
+### Test Structure
+
+- **`__tests__/actions.test.ts`** - Tests for server actions and business logic
+  - Member status validation
+  - Task filtering logic
+  - Database constraints
+
+- **`__tests__/components.test.tsx`** - Tests for React components
+  - Component rendering
+  - User interactions
+  - State management
+
+### Writing Tests
+
+```typescript
+import { describe, it, expect, beforeEach, vi } from 'vitest'
+
+describe('Feature', () => {
+  beforeEach(() => {
+    // Setup before each test
+  })
+
+  it('should do something', () => {
+    expect(result).toBe(expected)
+  })
+})
+```
+
+### Key Testing Patterns
+
+**Mocking Supabase:**
+```typescript
+const mockSupabase = {
+  from: vi.fn().mockReturnThis(),
+  select: vi.fn().mockReturnThis(),
+  eq: vi.fn().mockReturnThis(),
+  single: vi.fn().mockResolvedValue({ data: { ...} }),
+}
+```
+
+**Testing Async Functions:**
+```typescript
+it('should fetch data', async () => {
+  const result = await myAsyncFunction()
+  expect(result).toBeDefined()
+})
+```
+
+## E2E Tests (Playwright)
+
+E2E tests are located in `e2e/` directory and test complete user flows across the entire application.
+
+### Test Structure
+
+- **`e2e/critical-flows.spec.ts`** - Critical user journeys
+  - Authentication and dashboard access
+  - Task creation and management
+  - Member operations
+  - Secrets/ops management
+
+### Writing E2E Tests
+
+```typescript
+import { test, expect } from '@playwright/test'
+
+test.describe('Feature', () => {
+  test.beforeEach(async ({ page }) => {
+    await page.goto('/path')
+  })
+
+  test('should do something', async ({ page }) => {
+    await page.click('button')
+    await expect(page.locator('text=Success')).toBeVisible()
+  })
+})
+```
+
+### Common E2E Patterns
+
+**Navigation:**
+```typescript
+await page.goto('/tasks', { waitUntil: 'networkidle' })
+```
+
+**Interaction:**
+```typescript
+await page.click('button:has-text("Add")')
+await page.fill('input[name="title"]', 'New Task')
+```
+
+**Assertions:**
+```typescript
+await expect(page.locator('text=Task created')).toBeVisible()
+expect(page.url()).toContain('/tasks')
+```
+
+## Coverage
+
+Run tests with coverage:
+
+```bash
+npm test -- --coverage
+```
+
+Coverage reports are generated in `coverage/` directory.
+
+## CI/CD Integration
+
+Tests are configured to run in CI environments. Key CI-specific behaviors:
+
+- E2E tests retry 2x on failure
+- Screenshots/videos saved for failed tests
+- Full parallelization in CI
+
+## Debugging
+
+**Vitest:**
+```bash
+npm test -- --inspect-brk
+```
+
+**Playwright:**
+```bash
+npm run test:e2e -- --debug
+```
+
+## Best Practices
+
+1. **Test Behavior, Not Implementation** - Test what the user sees, not how code works
+2. **Keep Tests Isolated** - Each test should be independent
+3. **Use Meaningful Names** - Test names should describe what's being tested
+4. **Mock External Dependencies** - Mock Supabase, APIs, etc.
+5. **Test Happy & Sad Paths** - Test both success and failure scenarios
+
+## Adding New Tests
+
+When adding features:
+
+1. Add unit tests in `__tests__/` for business logic
+2. Add E2E tests in `e2e/` for user flows
+3. Run `npm test` to verify
+4. Check coverage with `npm test -- --coverage`
+
+## Troubleshooting
+
+**Tests timing out:**
+- Increase timeout: `test('...', async () => {...}, { timeout: 10000 })`
+
+**Playwright can't find elements:**
+- Use `--debug` to step through: `npm run test:e2e -- --debug`
+- Check selectors with: `await page.pause()`
+
+**Vitest isolation issues:**
+- Clear mocks: `vi.clearAllMocks()` in `beforeEach`
+- Reset modules: `vi.resetModules()`
