要点：
require_once 'PHPUnit/Framework.php' 语句是必须的。
编写的测试用例(usecase)是一个 PHP 脚本，需要在测试用例脚本中包含需要测试的代码。
测试用例的主体必须写在类中，类名建议和文件名保持一致，还必须是 PHPUnit_Framework_TestCase 的派生类。
每一个测试用例都是一个 public 类型的成员函数，必须以 test 开头。
程序的输出使用 assert* 系列函数（assertEquals、assertNotEquals、assertTrue、assertFalse、assertSame、setExpectedException）来进行验证（参见 http://www.phpunit.de 网站上的 PHPUnit 手册）。
运行：
该测试用例需要在命令窗口下键入 phpunit ArrayTest.php 来运行，而不是用浏览器打开它。结果如下所示：
C:\Program Files\Zend\Apache2\htdocs\unit_test>phpunit ArrayTest.php
PHPUnit 3.4.14 by Sebastian Bergmann.
..
Time: 1 second, Memory: 3.75Mb
OK (2 tests, 2 assertions)
其中的两个点“..”表示，两个测试用例全都通过。
添加一个成员函数：
public function testArrayContains2Element()
{
$fixture = array();
$fixture[] = 'Element';
$this->assertTrue(sizeof($fixture)==2);
}
然后再次测试，报告：
PHPUnit 3.4.14 by Sebastian Bergmann.
..F
Time: 0 seconds, Memory: 3.75Mb
There was 1 failure:
1) ArrayTest::testArrayContains2Element
Failed asserting that is true.
C:\Program Files\Zend\Apache2\htdocs\unit_test\ArrayTest.php:27
FAILURES!
Tests: 3, Assertions: 3, Failures: 1.
其中的“..F”表示，两个测试用例通过，一个失败。并提示了出错的位置。
PHPUnit 命令行工具输出的指示字符：
. 当测试成功时输出
F 当运行测试方法过程中一个断言失败时输出
E 当运行测试方法过程中产生一个错误时输出
S 当测试被跳过时输出
I 当测试被标记为不完整或未实现时输出
PHPUnit 的失败和错误是不同的。失败是指违反 PHPUnit 语法，例如 assertEquals() 调用失败。错误是指异常或 PHP 错误。有时这种区分非常有用，因为错误通常比失败容易修复。如果你得到一大串问题，最好先解决所有错误，然后再看还有没有失败。
3.2 使用数据提供者
测试方法可接受参数。这些参数将由一个数据提供者方法提供（provider()）。要用到的数据提供着方法是用@dataProvider注解指定的。
数据提供者方法必须是public和static的，而且返回值必须是数组的数组或者实现了Iterator接口并且每次迭代产生一个数组的对象。对于每个数组（即集合的部分），都将以其内容为参数调用测试方法。
