Note to self in case I need to do this again…

Commands assumes the PHP install is in C:\wamp\bin\php\php5.3.13 and that this path is already added to the PATH environment variable.

Install PEAR

1. Download go-pear.phar and Save it as C:\wamp\bin\php\php5.3.13\pear\go-pear.phar.
2. Open an elevated command prompt.
3. Go to the PHP directory.
   > cd \wamp\bin\php\php5.3.13
4. Install PEAR, pressing enter to accept defaults and Y to alter php.ini.
   > php .\pear\go-pear.phar
5. Add environment variables.
   > start PEAR_ENV.reg

Install PhpUnit

1. Make sure pear is fully up to date (should be if we just installed it)
   > pear upgrade-all
2. Add pear channels.
   > pear channel-discover components.ez.no
   > pear channel-discover pear.phpunit.de
   > pear channel-discover pear.symfony.com
3. Install PHPUnit with all dependencies.
   > pear install --alldeps phpunit/PHPUnit
4. Verify installation by checking version.
   > phpunit --version
