PHPUnit is a programmer-oriented testing framework for PHP. It is an instance of the xUnit architecture for unit testing frameworks.
It is used for the purpose of unit testing for PHP code. PHPUnit was created by Sebastian Bergmann and its development is hosted on GitHub.
Purpose: Its purpose is to verify functionality and impact of newly written code by developers. By running the unit test cases a developer can easily find mistakes in their business logic or functionality of the previously written code. PHPUnit uses assertions to verify that the behavior of the specific component.
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. A developer can use different types of assertions for different types of expected results and hence can verify them easily. For assertion, PHPUnit provides a different function to assert actual output versus expected output.

- For using phpunit follow the steps from here.
Note : Although the code looks like of php but cann’t be compiled on php compiler. Use phpunit filename.php command to run the code at local machine.
