fix(docker): bind webpack dev server to all interfaces

Change WEBPACK_DEVSERVER_HOST from 127.0.0.1 to 0.0.0.0 to make the
frontend accessible from outside the Docker container. This fixes an
issue where the frontend was only accessible from inside the container.

 ### E2E Integration Testing
 
-For E2E testing, we recommend that you use a `docker compose` backend
+**Note: We are migrating from Cypress to Playwright. Use Playwright for new tests.**
+
+#### Playwright (Recommended - NEW)
+
+For E2E testing with Playwright, use the same `docker compose` backend:
 
 ```bash
 CYPRESS_CONFIG=true docker compose up --build
 ```
-`docker compose` will get to work and expose a Cypress-ready Superset app.
-This app uses a different database schema (`superset_cypress`) to keep it isolated from
-your other dev environment(s), a specific set of examples, and a set of configurations that
-aligns with the expectations within the end-to-end tests.  Also note that it's served on a
-different port than the default port for the backend (`8088`).
 
-Now in another terminal, let's get ready to execute some Cypress commands. First, tell cypress
-to connect to the Cypress-ready Superset backend.
+The backend setup is identical - this exposes a test-ready Superset app on port 8081 with isolated database schema (`superset_cypress`), test data, and configurations.
 
+Now in another terminal, run Playwright tests:
+
+```bash
+# Navigate to frontend directory (Playwright config is here)
+cd superset-frontend
+
+# Run all Playwright tests
+npm run playwright:test
+# or: npx playwright test
+
+# Run with interactive UI for debugging
+npm run playwright:ui
+# or: npx playwright test --ui
+
+# Run in headed mode (see browser)
+npm run playwright:headed
+# or: npx playwright test --headed
+
+# Run specific test file
+npx playwright test tests/auth/login.spec.ts
+
+# Run with debug mode (step through tests)
+npm run playwright:debug tests/auth/login.spec.ts
+# or: npx playwright test --debug tests/auth/login.spec.ts
+
+# Generate test report
+npx playwright show-report
 ```
+
+Configuration is in `superset-frontend/playwright.config.ts`. Base URL is automatically set to `http://localhost:8088` but will use `PLAYWRIGHT_BASE_URL` if provided.
+
+#### Cypress (DEPRECATED - will be removed in Phase 5)
+
+:::warning
+Cypress is being phased out in favor of Playwright. Use Playwright for all new tests.
+:::
+
+```bash
+# Set base URL for Cypress
 CYPRESS_BASE_URL=http://localhost:8081
 ```

+# Playwright E2E Tests for Superset
+
+This directory contains Playwright end-to-end tests for Apache Superset, designed as a replacement for the existing Cypress tests during the migration to Playwright.
+
+## Architecture
+
+```
+playwright/
+├── components/core/     # Reusable UI components
+├── pages/              # Page Object Models  
+├── tests/              # Test files organized by feature
+├── utils/              # Shared constants and utilities
+└── README.md           # This file
+```
+
+## Design Principles
+
+We follow **YAGNI** (You Aren't Gonna Need It), **DRY** (Don't Repeat Yourself), and **KISS** (Keep It Simple, Stupid) principles:
+
+- Build only what's needed now
+- Reuse existing patterns and components
+- Keep solutions simple and maintainable
+
+## Component Architecture
+
+### Core Components (`components/core/`)
+
+Reusable UI interaction classes for common elements:
+
+- **Form**: Container with properly scoped child element access
+- **Input**: Supports `fill()`, `type()`, and `pressSequentially()` methods
+- **Button**: Standard click, hover, focus interactions
+
+**Usage Example:**
+```typescript
+import { Form } from '../components/core';
+
+const loginForm = new Form(page, '[data-test="login-form"]');
+const usernameInput = loginForm.getInput('[data-test="username-input"]');
+await usernameInput.fill('admin');
+```
+
+### Page Objects (`pages/`)
+
+Each page object encapsulates:
+- **Actions**: What you can do on the page
+- **Queries**: Information you can get from the page  
+- **Selectors**: Centralized in private static SELECTORS constant
+- **NO Assertions**: Keep assertions in test files
+
+**Page Object Pattern:**
+```typescript
+export class AuthPage {
+  // Selectors centralized in the page object
+  private static readonly SELECTORS = {
+    LOGIN_FORM: '[data-test="login-form"]',
+    USERNAME_INPUT: '[data-test="username-input"]',
+  } as const;
+
+  // Actions - what you can do
+  async loginWithCredentials(username: string, password: string) { }
+
+  // Queries - information you can get  
+  async getCurrentUrl(): Promise<string> { }
+
+  // NO assertions - those belong in tests
+}
+```
+
+### Tests (`tests/`)
+
+Organized by feature/area (auth, dashboard, charts, etc.):
+- Use page objects for actions
+- Keep assertions in test files  
+- Import shared constants from `utils/`
+
+**Test Pattern:**
+```typescript
+import { test, expect } from '@playwright/test';
+import { AuthPage } from '../../pages/AuthPage';
+import { LOGIN } from '../../utils/urls';
+
+test('should login with correct credentials', async ({ page }) => {
+  const authPage = new AuthPage(page);
+  await authPage.goto();
+  await authPage.loginWithCredentials('admin', 'general');
+
+  // Assertions belong in tests, not page objects
+  expect(await authPage.getCurrentUrl()).not.toContain(LOGIN);
+});
+```
+
+### Utilities (`utils/`)
+
+Shared constants and utilities:
+- **urls.ts**: URL paths and request patterns
+- Keep flat exports (no premature namespacing)
+
+## Contributing Guidelines
+
+### Adding New Tests
+
+1. **Check existing components** before creating new ones
+2. **Use page objects** for page interactions  
+3. **Keep assertions in tests**, not page objects
+4. **Follow naming conventions**: `feature.spec.ts`
+
+### Adding New Components
+
+1. **Follow YAGNI**: Only build what's immediately needed
+2. **Use Locator-based scoping** for proper element isolation
+3. **Support both string selectors and Locator objects** via constructor overloads
+4. **Add to `components/core/index.ts`** for easy importing
+
+### Adding New Page Objects
+
+1. **Centralize selectors** in private static SELECTORS constant
+2. **Import shared constants** from `utils/urls.ts`
+3. **Actions and queries only** - no assertions
+4. **Use existing components** for DOM interactions
+
+## Running Tests
+
+```bash
+# Run all tests
+npm run playwright:test
+# or: npx playwright test
+
+# Run specific test file
+npx playwright test tests/auth/login.spec.ts
+
+# Run with UI mode for debugging
+npm run playwright:ui
+# or: npx playwright test --ui
+
+# Run in headed mode (see browser)
+npm run playwright:headed
+# or: npx playwright test --headed
+
+# Debug specific test file
+npm run playwright:debug tests/auth/login.spec.ts
+# or: npx playwright test --debug tests/auth/login.spec.ts
+```
+
+## Test Reports
+
+Playwright generates multiple reports for better visibility:
+
+```bash
+# View interactive HTML report (opens automatically on failure)
+npm run playwright:report
+# or: npx playwright show-report
+
+# View test trace for debugging failures
+npx playwright show-trace test-results/[test-name]/trace.zip
+```
+
+### Report Types
+
+- **List Reporter**: Shows progress and summary table in terminal
+- **HTML Report**: Interactive web interface with screenshots, videos, and traces
+- **JSON Report**: Machine-readable format in `test-results/results.json`
+- **GitHub Actions**: Annotations in CI for failed tests
+
+### Debugging Failed Tests
+
+When tests fail, Playwright automatically captures:
+- **Screenshots** at the point of failure
+- **Videos** of the entire test run
+- **Traces** with timeline and network activity
+- **Error context** with detailed debugging information
+
+All debugging artifacts are available in the HTML report for easy analysis.
+
+## Configuration
+
+- **Config**: `playwright.config.ts` - matches Cypress settings
+- **Base URL**: `http://localhost:8088` (assumes Superset running)
+- **Browsers**: Chrome only for Phase 1 (YAGNI)
+- **Retries**: 2 in CI, 0 locally (matches Cypress)
+
+## Migration from Cypress
+
+When porting Cypress tests:
+
+1. **Port the logic**, not the implementation
+2. **Use page objects** instead of inline selectors
+3. **Replace `cy.intercept/cy.wait`** with `page.waitForRequest()`
+4. **Use shared constants** from `utils/urls.ts`
+5. **Follow the established patterns** shown in `tests/auth/login.spec.ts`
+
+## Best Practices
+
+- **Centralize selectors** in page objects
+- **Centralize URLs** in `utils/urls.ts`  
+- **Use meaningful test descriptions**
+- **Keep page objects action-focused**
+- **Put assertions in tests, not page objects**
+- **Follow the existing patterns** for consistency
