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！
附执行结果：
