📚 Description

Actually It is my personal opinion. It is a POST method and it works well. But for the POST method almost all time body is required which items the user is providing. So I think for the POST method example if we provide readBody things then it would be slightly more nicer to understand. It will also stay different from GET method which is in test.get.ts.
