XamPP 安装/升级PHPUnit

PHPUnit是一个轻量级的PHP测试框架。它是在PHP5下面对JUnit3系列版本的完整移植，是xUnit测试框架家族的一员(它们都基于模式先锋KentBeck的设计)。
安装XAMPP，自动会安装pear和PHPUnit 但是，版本会很低，需要进行升级，我写一下我的升级步骤。
假设我的XAMPP 安装在G盘
1.进入DOS ，进入 G/XAMPP/PHP目录（如果把G/xampp/php添加到环境变量就不用进入指定文件夹了）。
2.升级pear 
pear upgrade pear

G:\xampp\php>pear upgrade pear
WARNING: channel "pear.php.net" has updated its protocols, use"channel-update p
ear.php.net" to update
pear/Console_Getopt requires PEAR Installer (version>= 1.8.0), installed versio
n is 1.7.2

PEAR: Optional feature gtk2installer available (PEAR'sPHP-GTK2-based installer)

PEAR: To install optional features use "pear installpear/PEAR#featurename"

3.查看pear版本
pear -V

G:\xampp\php>pear -V
PEAR Version: 1.9.4
PHP Version: 5.3.5
Zend Engine Version: 2.3.0
Running on: Windows NT LMM-PC 6.1 build 7601 (Unknow Windowsversion Home Basic
Edition Service Pack 1) i586

4.升级phpUnit发现失败。
pear upgradepear/phpUnit

G:\xampp\php>pear upgrade pear/phpUnit
pear/phpUnit is already installed and is the same as thereleased version 1.3.2
upgrade failed

5.需要卸载原来的版本

pear uninstallpear/phpUnit

G:\xampp\php>pear uninstall pear/phpUnit
uninstall ok: channel://pear.php.net/PHPUnit-1.3.2

6.设置频道
pear config-set auto_discover 1
pear channel-discover components.ez.no
pear channel-discover pear.phpunit.de
pear channel-discover pear.symfony-project.com

G:\xampp\php>pear config-set auto_discover 1
config-set succeeded

G:\xampp\php>pear channel-discover components.ez.no
Adding Channel "components.ez.no" succeeded
Discovery of channel "components.ez.no" succeeded

G:\xampp\php>pear channel-discover pear.phpunit.de

Discovery of channel "pear.phpunit.de" succeeded

G:\xampp\php>pear channel-discover pear.symfony-project.com
Adding Channel "pear.symfony-project.com" succeeded
Discovery of channel "pear.symfony-project.com"succeeded

7.安装phpunit
pear install --alldeps phpunit/PHPUnit

G:\xampp\php>pear install --alldeps phpunit/PHPUnit
phpunit/PHP_CodeCoverage can optionally use PHP extension"xdebug" (version >= 2
.0.5)
phpunit/PHP_Invoker requires PHP extension "pcntl"

8.查看phpunit版本，成功~
phpunit -V
G:\xampp\php>phpunit -V
PHPUnit 3.6.10 by Sebastian Bergmann.
unrecognized option -- V

我走到第8步(phpunit -V)的时候，报错了

Fatal error: Call to undefined method PHP_CodeCoverage_Filter::getInstance() in

C:\xampp\php\phpunit on line 39

需要执行以下指令后才正常

pear install --force --alldeps phpunit/PHPUnit
