and extend the normal ``\PHPUnit\Framework\TestCase``.

When testing your commands, it could be useful to understand how your command
reacts on different settings like the width and the height of the terminal.
Thanks to the :class:`Symfony\\Component\\Console\\Terminal` class, you can
have access to such information::

use Symfony\Component\Console\Terminal;

$terminal = new Terminal();

// access to number of lines available
$height = $terminal->getHeight();

// access to number of columns available
$width = $terminal->getWidth();

By default, the ``Terminal`` class uses the values of the
``LINES`` and ``COLUMNS`` system environment variables.
