PHP

In order to perform the kata, first of all you will need to install all of the dependencies. This can be done using composer (standing from the "php" directory")

wget http://getcomposer.org/composer.phar
php composer.phar install

Next, to execute the unit tests you need run this from the php directory

php bin/phpunit

Coverage

If your IDE doesn't handle it you can launch and visualize it from the command line. Given you are in the php folder just run

php bin/phpunit --coverage-text

If you want to visualize it from the browser you have to run PHPUnit with this parameters

php bin/phpunit --coverage-html report/

Then visualize

open report/index.html

in a browser

Enjoy
