# Gegen lokale Umgebung
k6 run load-tests/web-apps.js
k6 run load-tests/auth-api.js
k6 run load-tests/sync-websocket.js
k6 run load-tests/llm-ollama.js

# Gegen Produktion (vorsichtig!)
k6 run -e BASE_URL=https://mana.how load-tests/web-apps.js

# Mit mehr/weniger Last
k6 run --vus 100 --duration 5m load-tests/web-apps.js

# JSON-Output fuer Grafana
k6 run --out json=results.json load-tests/web-apps.js
```
