/**
 * A TestCase defines the fixture to run multiple tests.
 *
 * To define a TestCase
 *
 *   1) Implement a subclass of PHPUnit_Framework_TestCase.
 *   2) Define instance variables that store the state of the fixture.
 *   3) Initialize the fixture state by overriding setUp().
 *   4) Clean-up after a test by overriding tearDown().
 *
 * Each test runs in its own fixture so there can be no side effects
 * among test runs.
 *
 * Here is an example:
 *
 * <code>
 * <?php
 * class MathTest extends PHPUnit_Framework_TestCase
 * {
 *     public $value1;
 *     public $value2;
 *
 *     protected function setUp()
 *     {
 *         $this->value1 = 2;
 *         $this->value2 = 3;
 *     }
 * }
 * ?>
 * </code>
 *
 * For each test implement a method which interacts with the fixture.
 * Verify the expected results with assertions specified by calling
 * assert with a boolean.
 *
 * <code>
 * <?php
 * public function testPass()
 * {
 *     $this->assertTrue($this->value1 + $this->value2 == 5);
 * }
 * ?>
 * </code>
