ContainerKata

Find the best solution to pack drums into containers by respecting the following rules :

• The container has a capacity limit and drums have different size
• All chemicals in a container cannot exceed the capacity limit.
• TNT drums require armored container
• Ammonia drums require ventilated container
• Biological samples and TNT should be separated.
• Water and Biological samples do not require any container feature.

DDD

Design matters : how it is possible to represent actual and expected behavior whithout a good design first ?

Types

Domain

• Types with primitives
• Fix primitives

Services

• Identity Services
• Identify where to not use exceptions

Implementation

Unit Test in the REPL

Little demo

Container specification Tests

Size for sand

TNT and Ammonia

Biological and TNT

What is the limit of our solution ?

• Is it hard to enumerate ?

Add unit test to prove the allocation space problem. Identity through types cardinality.

• What are properties ?
• Is it easy to prove
• It is easy to verify ?
