PHPUnit - Migrate from PEAR Install to PHAR (Windows & Linux)

Migrate PHPUnit from PEAR toPHAR

You have installed PHPUnit with PEAR, but the installation method is migrating and you keep getting the error message:

You have installed PHPUnit via PEAR. This installation method is no longer supported and http://pear.phpunit.de/ will be shut down no later than December, 31 2014.

Please read http://phpunit.de/manual/current/en/installation.html and learn how to use PHPUnit from a PHAR or install it via Composer. 

It lets you know that you haven't installed it the right way, but now how do you correct the problem and remove the annoying error message? 

First remove it (Windows & Linux):

pear uninstall phpunit/PHPUnit

Get and install PHPUnit using the phar, Linux (or Amazon EC2) version:

wget https://phar.phpunit.de/phpunit.phar
chmod +x phpunit.phar
mv phpunit.phar /usr/local/bin/phpunit
#and in my case, the phpunit executable also needed to be placed here
cp /usr/local/bin/phpunit /usr/bin/phpunit

Get and Install PHPUnit using the phar, Windows version:

Download the .phar file to somewhere you can run it with php.

1. Open this address in a browser and save to your disk: https://phar.phpunit.de/phpunit.phar 
2. Open the command line and go to the directory (cd {savepath}) you have saved the file in. 
3. Execute tests with: php phpunit.phar testfile.php  
4. Copy phpunit.phar to overwrite your existing phpunit file (replace c:\php\phpunit with your installed location).  Back up the original phpunit file just in case.
   copy c:\php\phpunit c:\php\phpunit.bakcopy phpunit.phar c:\php\phpunit

NOTE:

If you are getting the error below when running your tests:
Failed opening required 'PHPUnit/Autoload.php'
You may need to remove or comment out the Autoload include line .  This file has already been included in the .phar PHP Archive.

//require_once 'PHPUnit/Autoload.php';

Now, use this testing framework to check your code and help you feel confident when deploying your applications.

There are a great number of resources on the official PHPUnit page that you should check out if you want to learn more about PHPUnit and how to use it to your advantage - PHPUnit Presentations.
