PHPUnit是什么?
它是一款轻量级的php测试框架
为什么要用PHPUnit?
1. facebook在用
2. 可以通过命令操控测试脚本
3. 可以测试性能
4. 可以测试代码覆盖率
5. 可以自动化的更新测试用例的参数数据
6. 各种格式的日志
6. 最最重要的是,功能如此炫,使用起来还特别简单
PHPUnit的安装
- pear channel-discover pear.phpunit.de
- pear install phpunit/PHPUnit
pear channel-discover pear.phpunit.de
pear install phpunit/PHPUnit
快速入门
- <?php
- require_once 'PHPUnit/Framework.php';
- class ArrayTest extends PHPUnit_Framework_TestCase
- {
- public function testNewArrayIsEmpty()
- {
- // 创建数组fixture。
- $fixture = array();
- // 断言数组fixture的尺寸是0。
- $this->assertEquals(0, sizeof($fixture));
- }
- }
- ?>
<?php
require_once 'PHPUnit/Framework.php';
class ArrayTest extends PHPUnit_Framework_TestCase
{
public function testNewArrayIsEmpty()
{
// 创建数组fixture。
$fixture = array();
// 断言数组fixture的尺寸是0。
$this->assertEquals(0, sizeof($fixture));
}
}
?>
1. ArrayTest为测试类
2. ArrayTest 继承于PHPUnit_Framework_TestCase
3.测试方法testNewArrayIsEmpty(),测试方法必须为public权限,一般以test开头,或者你也可以选择给其加注释@test来表明该函数为测试函数
- /**
- * @test
- */
- public function testNewArrayIsEmpty()
- {
- $fixture = array();
- $this->assertEquals(0, sizeof($fixture));
- }
/**
* @test
*/
public function testNewArrayIsEmpty()
{
$fixture = array();
$this->assertEquals(0, sizeof($fixture));
}

高级功能
你是否已经厌烦了在每一个测试方法命名前面加一个test,是否因为只是调用的参数不同,却要写多个测试用例而纠结?我最喜欢的高级功能,现在隆重推荐给你,叫做框架生成器
- <?php
- class Calculator
- {
- public function add($a, $b)
- {
- return $a + $b;
- }
- }
- ?>
<?php
class Calculator
{
public function add($a, $b)
{
return $a + $b;
}
}
?>
命令行启动测试用例
- phpunit --skeleton Calculator
- PHPUnit 3.2.10 by Sebastian Bergmann.
- Wrote test class skeleton for Calculator to CalculatorTest.php.
phpunit --skeleton Calculator
PHPUnit 3.2.10 by Sebastian Bergmann.
Wrote test class skeleton for Calculator to CalculatorTest.php.
简单么?简单,但是它其实没有什么意义,因为没有测试数据,怎样加数据,哦哦哦,重头戏来了
- <?php
- class Calculator
- {
- /**
- * @assert (0, 0) == 0
- * @assert (0, 1) == 1
- * @assert (1, 0) == 1
- * @assert (1, 1) == 2
- */
- public function add($a, $b)
- {
- return $a + $b;
- }
- }
- ?>
<?php
class Calculator
{
/**
* @assert (0, 0) == 0
* @assert (0, 1) == 1
* @assert (1, 0) == 1
* @assert (1, 1) == 2
*/
public function add($a, $b)
{
return $a + $b;
}
}
?>
原始类中的每个方法都进行@assert注解的检测。这些被转变为测试代码,像这样
/**
* Generated from @assert (0, 0) == 0.
*/
public function testAdd() {
$o = new Calculator;
$this->assertEquals(0, $o->add(0, 0));
}
下面是运行生成的测试用例类的输出。
- phpunit CalculatorTest
- PHPUnit 3.2.10 by Sebastian Bergmann.

- Time: 0 seconds
- OK (4 tests)
