You'll have to create a Smart Hello World.

Your app need to take a name (by default world if none is provided) and write a greeting depending on the time of the day:

• Good morning X if current hour is < 12h00
• Good afternoon X if current hour is > 12h00 and < 20h00
• Good night Xif current hour is after 20h00 and before 6h00 in the morning

You need to make it right:

• take care of the boundaries of the system (what are your functional code and your technical code, what are invariants,...)
• your business code should be testable
