# ThrillWiki E2E Testing with Playwright

This directory contains comprehensive end-to-end tests for ThrillWiki using Playwright.

## Overview

These tests replace the problematic backend integration tests with proper browser-based E2E tests that:
- ✅ Test the actual user experience
- ✅ Respect security policies (RLS)
- ✅ Validate the complete submission → moderation → approval flow
- ✅ Run in real browsers (Chromium, Firefox, WebKit)
- ✅ Support parallel execution for speed
- ✅ Capture videos and screenshots on failure

## Prerequisites

1. **Node.js** and **npm** installed
2. **Supabase service role key** for test setup/teardown:
   ```bash
   export SUPABASE_SERVICE_ROLE_KEY="your-service-role-key"
   ```
3. **Test users** (optional, will be auto-created):
   ```bash
   export TEST_USER_EMAIL="test-user@thrillwiki.test"
   export TEST_USER_PASSWORD="TestUser123!"
   export TEST_MODERATOR_EMAIL="test-moderator@thrillwiki.test"
   export TEST_MODERATOR_PASSWORD="TestModerator123!"
   ```

## Installation

```bash
# Install Playwright and browsers
npm install
npx playwright install
```

## Running Tests

### All tests
```bash
npx playwright test
```

### Specific test file
```bash
npx playwright test tests/e2e/auth/login.spec.ts
```

### Specific test suite
```bash
npx playwright test tests/e2e/submission/
```

### Run in headed mode (see browser)
```bash
npx playwright test --headed
```

### Run in UI mode (interactive)
```bash
npx playwright test --ui
```

### Run with specific browser
```bash
npx playwright test --project=chromium
npx playwright test --project=firefox
npx playwright test --project=webkit
```

### Run tests with specific user role
```bash
npx playwright test --project=moderator
npx playwright test --project=admin
```

## Debugging Tests

### Debug mode
```bash
npx playwright test --debug
```

### Show test report
```bash
npx playwright show-report
```

### View trace for failed test
```bash
npx playwright show-trace trace.zip
```

## Writing New Tests

### 1. Create a test file
```typescript
// tests/e2e/feature/my-feature.spec.ts
import { test, expect } from '@playwright/test';

test.describe('My Feature', () => {
  test('should do something', async ({ page }) => {
    await page.goto('/my-feature');
    await expect(page.getByText('Hello')).toBeVisible();
  });
});
```

### 2. Use Page Objects (recommended)
```typescript
import { MyFeaturePage } from '../../helpers/page-objects/MyFeaturePage';

test('should use page object', async ({ page }) => {
  const myFeature = new MyFeaturePage(page);
  await myFeature.goto();
  await myFeature.doSomething();
  await myFeature.expectSuccess();
});
```

### 3. Use test data generators
```typescript
import { generateParkData } from '../../fixtures/test-data';

test('should create park', async ({ page }) => {
  const parkData = generateParkData({ name: 'Custom Park' });
  // Use parkData in your test
});
```

### 4. Clean up test data
```typescript
import { cleanupTestData } from '../../fixtures/database';

test.afterAll(async () => {
  await cleanupTestData();
});
```

## Test Data Management

All test data is automatically marked with `is_test_data: true` and cleaned up after tests run.

### Manual cleanup
If tests fail and leave data behind:
```typescript
import { cleanupTestData } from './fixtures/database';
await cleanupTestData();
```

Or use the "Emergency Cleanup" button in the admin UI at `/admin/settings`.

## Authentication

Tests use pre-authenticated browser contexts to avoid logging in for every test:

- `.auth/user.json` - Regular user
- `.auth/moderator.json` - Moderator with AAL2
- `.auth/admin.json` - Admin with AAL2
- `.auth/superuser.json` - Superuser with AAL2

These are created automatically during global setup.

## CI/CD Integration

Tests run automatically on GitHub Actions:
- On every pull request
- On push to main branch
- Results posted as PR comments

See `.github/workflows/playwright.yml` for configuration.

## Best Practices

1. **Use Page Objects** - Encapsulate page interactions
2. **Mark test data** - Always set `is_test_data: true`
3. **Clean up** - Use `test.afterAll()` or `test.afterEach()`
4. **Use fixtures** - Reuse auth, database, and test data helpers
5. **Test user flows** - Not individual functions
6. **Avoid hardcoded waits** - Use `waitForLoadState()` or `waitForSelector()`
7. **Take screenshots** - On failure (automatic)
8. **Parallelize** - Tests run in parallel by default

## Common Issues

### "Service role key not configured"
Set the `SUPABASE_SERVICE_ROLE_KEY` environment variable.

### "Test data not cleaned up"
Run `npx playwright test --project=cleanup` or use the admin UI emergency cleanup button.

### "Lock timeout"
Some tests involving moderation locks may take longer. Increase timeout:
```typescript
test('my slow test', async ({ page }) => {
  test.setTimeout(120000); // 2 minutes
  // ...
});
```
