Unit test
In computer programming, unit testing is a method by which individual units of source code are tested to determine if they are fit for use.A unit is the smallest testable part of an application. In procedural programming a unit could be an entire module but is more commonly an individual function...

Purpose
PHPUnit was created with the view that the sooner you detect your code mistakes, the quicker you can fix them. Like all Unit testing frameworks PHPUnit uses assertions to verify that behaviour of the unit of code under test behaves as expected.Benefits
The goal of unit testing is to isolate each part of the program and show that the individual parts are correct. A unit test provides a strict, written contract that the piece of code must satisfy. As a result, unit tests find problems early in the development cycle.External links
