If you need a working dev environment and have Docker/Docker Compose, run docker-compose up -d
It will install php v7.1 and composer.
Otherwise, just use:
composer install
or
docker-compose exec bully composer install
It installs phpunit and use composer autoloader.
To run the app, just use:
php main.php
or
docker-compose exec bully php main.php
To run the tests, just use:
php vendor/bin/phpunit
or
docker-compose exec bully vendor/bin/phpunit
