Assert in java package

Assert in java package

A set of assertion methods useful for writing tests. Only failed assertions are recorded. These methods can be used directly: Assert.assertEquals(. ) , however, they read better if they are referenced through static import:

import static org.junit.Assert.*; . assertEquals(. );

Constructor Summary
protected	Assert () Protect constructor since it is a static only class
