title: Install PHPUNIT with Composer
body: <p>I have project on Symfony 2 and i would like use PHPUNIT on Windows 7. </p>
  
  <pre><code>On githut phpunit is:
  
  Composer
  
  Simply add a dependency on phpunit/phpunit to your project's composer.json file if you use Composer to manage the dependencies of your project. Here is a minimal example of a composer.json file that just defines a development-time dependency on PHPUnit 3.7:
  
  {
      "require-dev": {
          "phpunit/phpunit": "3.7.*"
      }
  }
  For a system-wide installation via Composer, you can run:
  
  composer global require 'phpunit/phpunit=3.7.*'
  Make sure you have ~/.composer/vendor/bin/ in your path.
  </code></pre>
  
  <p>First i use system-wide installation but i dont know when this installed. 
  Next i add to my composer.json require-dev.
  This installed phpunit in C:/wamp/www/myproject/vendor/symfony. Next i try commands:</p>
  
  <pre><code> composer install --dev
  </code></pre>
  
  <p>And i can't use phpunit. In cmd.exe i enter "phpunit" and i have error:</p>
  
  <pre><code>'phpunit' is not recognized as an internal or external command operable program or batch file
  </code></pre>
  
  <p>How can i use phpunit? I have Windows 7, Wamp server and php 5.4.12.</p>
