Create the test class using phpunit-skelgen.phar

PHPUnit and Netbeans Integration

Generic setup for PHPUnit within NetBeans IDE

Tools -> Option -> PHP -> PHP Framework -> PHPUnit

Create a new PHP project with the above Source for calcualater.php

Setup PHPUnit as test Provider

Right Click Project [ PhpUnitTest3] -> Properties -> Testing -> Add Folder

Create the PHP Test Classes

Right Click on Calculator.php -> Tools -> Create/Update Tests

 
Netbeans should create  CalculatorTest.php in out tests directory by running: 
"D:\xampp\php\php.exe" "D:\PHP\phpunit\phpunit-skelgen.phar" "--test" "--" "Calculator" 
    "D:\xampp\htdocs\PhpUnitTest3\Calculator.php" "CalculatorTest" "D:\xampp\htdocs\PhpUnitTest3\tests\CalculatorTest.php"
PHPUnit Skeleton Generator 1.2.1 by Sebastian Bergmann.

Wrote skeleton for "CalculatorTest" to "D:\xampp\htdocs\PhpUnitTest3\tests\CalculatorTest.php".  

Copy above bootstrap.php to our test folder and modify PHPUnit settings

Right Click Project [ PhpUnitTest3] -> Properties -> PHPUnit

Project Files and Directories sould now look like: 
* Directory structure:
 * ├── PhpUnitTest
 *         ├── Calculator.php
 *         ├── tests
 *               ├── bootstrap.php
 *               ├── CalculatorTest.php

Finally run PHPUnit tests

Right Click Calculator.php -> Test
