TeapotamusSteepI'm a teapot. No coffee.What it means
A joke code from RFC 2324: a teapot refuses to brew coffee.
Where you meet it
Easter eggs in APIs. A nice bonus in an interview.
What to test
- If the product has an easter egg (e.g., /teapot), call it, then call a few real endpoints → the real ones still work normally.
- Check monitoring and alerts after calling the easter egg → no alarm about an unknown error.
