App-Stabilitäts- und Testing-Strategie für ulo.ad

Executive Summary

Dieser Bericht analysiert die aktuellen Stabilitätsprobleme der ulo.ad-Anwendung und bietet konkrete Lösungsansätze für eine robuste, fehlerfreie Produktionsumgebung. Die identifizierten Probleme (fehlerhafte PocketBase-Rules, inkonsistente Feldnamen) hätten durch systematisches Testing verhindert werden können.

Identifizierte Probleme

1. Datenbankebene

• Problem: Inkonsistente Feldnamen zwischen Code und Datenbank (user vs user_id)
• Auswirkung: Funktionen schlagen in Produktion fehl, obwohl sie lokal funktionieren
• Root Cause: Fehlende Schema-Validierung und Integrationstests

2. API Rules

• Problem: Falsche PocketBase Collection Rules (z.B. user_id = @request.auth.id in createRule)
• Auswirkung: Benutzer können keine Tags/Ordner erstellen
• Root Cause: Keine automatisierten Tests für API-Berechtigungen

Empfohlene Testing-Strategie

1. Unit Tests (Vitest)

// tests/unit/pocketbase.spec.ts
import { describe, it, expect, beforeEach } from 'vitest';
import { pb, generateTagSlug, generateShortCode } from '$lib/pocketbase';

describe('PocketBase Utilities', () => {
	describe('generateTagSlug', () => {
		it('should generate valid slugs', () => {
			expect(generateTagSlug('My Tag')).toBe('my-tag');
			expect(generateTagSlug('Special!@#$Tag')).toBe('special-tag');
			expect(generateTagSlug('  Trimmed  ')).toBe('trimmed');
		});
	});

	describe('generateShortCode', () => {
		it('should generate codes of correct length', () => {
			const code = generateShortCode(8);
			expect(code).toHaveLength(8);
			expect(code).toMatch(/^[a-zA-Z0-9]+$/);
		});
	});
});

2. Integration Tests

// tests/integration/tags.spec.ts
import { describe, it, expect, beforeEach } from 'vitest';
import { pb } from '$lib/pocketbase';

describe('Tags Integration', () => {
	let testUser;

	beforeEach(async () => {
		// Setup test user
		testUser = await pb.collection('users').create({
			email: `test-${Date.now()}@example.com`,
			password: 'testpassword123',
			passwordConfirm: 'testpassword123',
		});

		await pb.collection('users').authWithPassword(testUser.email, 'testpassword123');
	});

	it('should create a tag successfully', async () => {
		const tag = await pb.collection('tags').create({
			name: 'Test Tag',
			slug: 'test-tag',
			user_id: testUser.id,
			color: '#3B82F6',
			is_public: false,
		});

		expect(tag.name).toBe('Test Tag');
		expect(tag.user_id).toBe(testUser.id);
	});

	it('should enforce user ownership on update', async () => {
		const tag = await pb.collection('tags').create({
			name: 'My Tag',
			slug: 'my-tag',
			user_id: testUser.id,
		});

		// Try to update with different user
		const otherUser = await pb.collection('users').create({
			email: `other-${Date.now()}@example.com`,
			password: 'testpassword123',
			passwordConfirm: 'testpassword123',
		});

		await pb.collection('users').authWithPassword(otherUser.email, 'testpassword123');

		await expect(pb.collection('tags').update(tag.id, { name: 'Hacked' })).rejects.toThrow();
	});
});

3. E2E Tests (Playwright)

// e2e/auth.test.ts
import { test, expect } from '@playwright/test';

test.describe('Authentication Flow', () => {
	test('should register a new user', async ({ page }) => {
		await page.goto('/register');

		const email = `test-${Date.now()}@example.com`;
		await page.fill('input[name="email"]', email);
		await page.fill('input[name="password"]', 'SecurePass123!');
		await page.fill('input[name="passwordConfirm"]', 'SecurePass123!');
		await page.fill('input[name="username"]', `user${Date.now()}`);

		await page.click('button[type="submit"]');

		// Should redirect to dashboard
		await expect(page).toHaveURL('/dashboard');
		await expect(page.locator('text=Welcome')).toBeVisible();
	});

	test('should login existing user', async ({ page }) => {
		await page.goto('/login');

		await page.fill('input[name="email"]', 'existing@example.com');
		await page.fill('input[name="password"]', 'password123');

		await page.click('button[type="submit"]');

		await expect(page).toHaveURL('/dashboard');
	});

	test('should handle login errors', async ({ page }) => {
		await page.goto('/login');

		await page.fill('input[name="email"]', 'wrong@example.com');
		await page.fill('input[name="password"]', 'wrongpass');

		await page.click('button[type="submit"]');

		await expect(page.locator('.error-message')).toContainText('Invalid credentials');
	});
});

// e2e/tags-folders.test.ts
test.describe('Tags and Folders Management', () => {
	test.beforeEach(async ({ page }) => {
		// Login first
		await page.goto('/login');
		await page.fill('input[name="email"]', 'test@example.com');
		await page.fill('input[name="password"]', 'password123');
		await page.click('button[type="submit"]');
		await expect(page).toHaveURL('/dashboard');
	});

	test('should create a new tag', async ({ page }) => {
		await page.goto('/dashboard/tags');

		await page.click('button:has-text("New Tag")');
		await page.fill('input[name="name"]', 'Work Projects');
		await page.click('button[type="submit"]');

		await expect(page.locator('text=Work Projects')).toBeVisible();
	});

	test('should create a new folder', async ({ page }) => {
		await page.goto('/dashboard/folders');

		await page.click('button:has-text("New Folder")');
		await page.fill('input[name="name"]', 'my-portfolio');
		await page.fill('input[name="display_name"]', 'My Portfolio');
		await page.click('button[type="submit"]');

		await expect(page.locator('text=My Portfolio')).toBeVisible();
	});
});

4. API Contract Tests

// tests/api/pocketbase-schema.spec.ts
import { describe, it, expect } from 'vitest';
import { pb } from '$lib/pocketbase';

describe('PocketBase Schema Validation', () => {
	it('should have correct fields in tags collection', async () => {
		const collection = await pb.collections.getOne('tags');

		const fields = collection.schema.map((f) => f.name);
		expect(fields).toContain('user_id'); // NOT 'user'
		expect(fields).toContain('name');
		expect(fields).toContain('slug');
		expect(fields).toContain('color');
		expect(fields).toContain('icon');
	});

	it('should have correct rules for tags collection', async () => {
		const collection = await pb.collections.getOne('tags');

		// Create rule should only check authentication
		expect(collection.createRule).toBe('@request.auth.id != ""');

		// Update/Delete should check ownership
		expect(collection.updateRule).toContain('user_id = @request.auth.id');
		expect(collection.deleteRule).toContain('user_id = @request.auth.id');
	});
});

Monitoring und Error Tracking

1. Sentry Integration

// src/hooks.client.ts
import * as Sentry from '@sentry/sveltekit';

Sentry.init({
	dsn: import.meta.env.PUBLIC_SENTRY_DSN,
	environment: import.meta.env.MODE,
	integrations: [Sentry.browserTracingIntegration(), Sentry.replayIntegration()],
	tracesSampleRate: 1.0,
	replaysSessionSampleRate: 0.1,
	replaysOnErrorSampleRate: 1.0,
});

export const handleError = Sentry.handleErrorWithSentry();

2. Health Checks

// src/routes/api/health/+server.ts
import { json } from '@sveltejs/kit';
import { pb } from '$lib/pocketbase';

export async function GET() {
	const checks = {
		app: 'ok',
		database: 'unknown',
		timestamp: new Date().toISOString(),
	};

	try {
		// Test database connection
		await pb.collection('users').getList(1, 1);
		checks.database = 'ok';
	} catch (error) {
		checks.database = 'error';
	}

	const status = checks.database === 'ok' ? 200 : 503;
	return json(checks, { status });
}

VITE_TEST_MODE=true

# .env.production
PUBLIC_POCKETBASE_URL=https://pb.ulo.ad
VITE_TEST_MODE=false

Schema Migration Strategy

1. Versionierte Migrationen

// scripts/migrate.js
import PocketBase from 'pocketbase';

const migrations = [
	{
		version: 1,
		name: 'fix_user_id_fields',
		up: async (pb) => {
			// Update tags collection
			const tagsCollection = await pb.collections.getOne('tags');
			tagsCollection.createRule = '@request.auth.id != ""';
			await pb.collections.update('tags', tagsCollection);

			console.log('✓ Fixed tags collection rules');
		},
	},
	{
		version: 2,
		name: 'add_missing_indexes',
		up: async (pb) => {
			// Add indexes for performance
			// Implementation here
		},
	},
];

async function runMigrations() {
	const pb = new PocketBase(process.env.POCKETBASE_URL);
	await pb.admins.authWithPassword(process.env.PB_ADMIN_EMAIL, process.env.PB_ADMIN_PASSWORD);

	for (const migration of migrations) {
		console.log(`Running migration ${migration.version}: ${migration.name}`);
		await migration.up(pb);
	}
}

runMigrations().catch(console.error);

Rollback Strategy

1. Database Backups

# Tägliche Backups
0 2 * * * /usr/local/bin/backup-pocketbase.sh

# backup-pocketbase.sh
#!/bin/bash
DATE=$(date +%Y%m%d_%H%M%S)
docker exec pocketbase-prod sqlite3 /pb_data/data.db ".backup /backups/backup_$DATE.db"
# Keep only last 30 days
find /backups -name "backup_*.db" -mtime +30 -delete

2. Blue-Green Deployment

# nginx.conf
upstream app_blue {
    server app-blue:3000;
}

upstream app_green {
    server app-green:3000;
}

server {
    listen 80;
    location / {
        proxy_pass http://app_blue;  # Switch to app_green for deployment
    }
}
