Travis: Initiating build for commit 'a21503543c43860f21d1fcf5a282ee822f17a103' on branch 'master': Refs #5031 The build is green: https://travis-ci.org/piwik/piwik we're running latest PHPUnit using composer.

Instructions to install PHPUnit, run `php composer.phar update` in the Piwik root directory.

                 Add the PHPUnit binary path to the your PATH environment variable. For example on Linux:
                 Edit `.bashrc` in your home directory and add the following line:

                     export PATH=/path/to/dir:$PATH

                 You will need to source your `.bashrc` or logout/login (or restart the terminal) for the changes to take effect.
                 To source your `.bashrc`, in your home directory simply type

                     $ source .bashrc

                 See [PHPUnit doc](http://www.phpunit.de/manual/current/en/installation.html).
