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:
http://www.cnblogs.com/x3d/p/phpunit-in-netbeans8.html
https://phpunit.de/manual/current/zh_cn/installation.html
https://github.com/sebastianbergmann/phpunit-skeleton-generator
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!
