PHPUnit 入门案例，phpunit入门案例

了解PHPUnit

本案例是关于创建三角形的一个单元测试入门案例，在netbeans环境中完成，关于在此环境中搭建phpunit这里不再描述，可以参考以下资料完成搭建工作：

原代码类：

 

<?php

class Triangle
{

    /**
     * 三条边 第一条边
     * @var int 
     */
    protected $a;

    /**
     * 三条边 第二条边
     * @var int 
     */
    protected $b;

    /**
     * 三条边 第三条边
     * @var int 
     */
    protected $c;

    /**
     * 类型
     * @var string 
     */
    protected $type;

    /**
     * 等边
     */
    const TYPE_EQUILATERAL = 'Equilateral';

    /**
     * 等腰
     */
    const TYPE_ISOSCELES = 'Isosceles';

    /**
     * 普通
     */
    const TYPE_ORDINARY = 'Ordinary';

    public function __construct($a = 0, $b = 0, $c = 0)
    {
        $this->initSide($a, $b, $c);
    }

    /**
     * 初始化三边
     * @param int $a
     * @param int $b
     * @param int $c
     */
    protected function initSide(&$a = 0, &$b = 0, &$c = 0)
    {
        $this->a = intval($a);
        $this->b = intval($b);
        $this->c = intval($c);
        return $this;
    }

    /**
     * 组建
     */
    public function create($a, $b, $c)
    {
        return $this->initSide($a, $b, $c)->verifySideIsValid();
    }

    /**
     * 获取类型
     */
    public function getType()
    {
        return $this->verifyType()->type;
    }

    /**
     * 验证三边是否有效
     * @return boolean
     */
    protected function verifySideIsValid()
    {
        if (intval($this->a) <= 0 || intval($this->b) <= 0 || intval($this->c) <= 0) {
            return false;
        }

        if ($this->a + $this->b <= $this->c) {
            return false;
        }
        if ($this->a + $this->c <= $this->b) {
            return false;
        }
        if ($this->b + $this->c <= $this->a) {
            return false;
        }
        if ($this->a - $this->b >= $this->c) {
            return false;
        }
        if ($this->a - $this->c >= $this->b) {
            return false;
        }
        if ($this->b - $this->c >= $this->a) {
            return false;
        }
        return true;
    }

    /**
     * 验证类型
     */
    protected function verifyType()
    {
        if ($this->isEquilateral()) {
            $this->type = self::TYPE_EQUILATERAL;
            return $this;
        }
        if ($this->isIsosceles()) {
            $this->type = self::TYPE_ISOSCELES;
            return $this;
        }
        $this->type = self::TYPE_ORDINARY;
        return $this;
    }

    /**
     * 是否为等边三角形
     */
    protected function isEquilateral()
    {
        return (($this->a == $this->b ) && ($this->b == $this->c)) ? true : false;
    }

    /**
     * 是否为等腰三角形
     */
    protected function isIsosceles()
    {
        return (($this->a == $this->b ) || ($this->b == $this->c) || ($this->a == $this->c)) ? true : false;
    }

}

生成的测试类文件：

<?php

/**
 * Generated by PHPUnit_SkeletonGenerator on 2016-03-13 at 19:49:12.
 */
class TriangleTest extends PHPUnit_Framework_TestCase
{

    /**
     * @var Triangle
     */
    protected $object;

    /**
     * Sets up the fixture, for example, opens a network connection.
     * This method is called before a test is executed.
     */
    protected function setUp()
    {
        $this->object = new Triangle;
    }

    /**
     * Tears down the fixture, for example, closes a network connection.
     * This method is called after a test is executed.
     */
    protected function tearDown()
    {
        
    }

    /**
     * @dataProvider addDataProvider
     * @covers Triangle::create
     * @todo   Implement testCreate().
     */
    public function testCreate($a, $b, $c)
    {
        // Remove the following lines when you implement this test.
        /**
          $this->markTestIncomplete(
          'This test has not been implemented yet.'
          );
         * 
         */
        /* 实现代码 */
        $this->assertTrue($this->object->create($a, $b, $c));
    }

    /**
     * @covers Triangle::getType
     * @todo   Implement testGetType().
     */
    public function testGetType()
    {
        // Remove the following lines when you implement this test.
        $this->markTestIncomplete(
                'This test has not been implemented yet.'
        );
    }

    /**
     * 测试用例
     * @return array
     */
    public function addDataProvider()
    {
        return [
            [3, 4, 5], //yes
            [2, 2, 2], //yes
            [8, 10, 8], //yes
            [2, 3, 4], //yes
            [1, 2, 3], //no
            [5, 6, 7], //yes
            [8, 8, 15], //yes
            [0, 0, 0], //no
            [-10, 2, 5], //no
            [0, 2, 1], //no
        ];
    }

}

这里需要注意，在我们执行“创建/更新测试”后生成的测试文件类与上面会有些不同，这里的测试用例是手动加上去的，这里具体实现可以查看手册里的说明！

附执行结果：
