# Code Test - Assertion Library

Language - Assertion in a code testing context.

Not to confound with assertion that are written in the code, this assertions are written in the test method only and are part of a test framework..

An assertion library helps you write your result expectation of a code in a unit test between:

• the value that you get from your function
• and the value that you expects.

This is the second component of a test framework.
