## Detailed Description

Message associated to an Exception.

A message is composed of two items:

- a short description (~20/30 characters)
- a list of detail strings

The short description is used to indicate how the detail strings should be interpreted. It usually indicates the failure types, such as "assertion failed", "forced failure", "unexpected exception caught", "equality assertion failed"... It should not contains new line character (
).

Detail strings are used to provide more information about the failure. It can contains the asserted expression, the expected and actual values in an equality assertion, some addional messages... Detail strings can contains new line characters (
).
