PHPUnit and Xdebug
Published on 2017-01-12
Having the Xdebug PHP extension always loaded slows down Composer and Phan.
But I do want to have Xdebug enabled for generating code coverage reports using PHPUnit.
It took me some time to figure this out, and it is not so hard.
First step: install the Xdebug extension, on Fedora:
$ sudo dnf -y install php-pecl-xdebug
Edit the file /etc/php.d/15-xdebug.ini to disable loading the extension:
;zend_extension=xdebug.so
Now, to enable this extension just for running PHPUnit:
$ php -dextension=/usr/lib64/php/modules/xdebug.so /usr/bin/phpunit \
--coverage-html coverage
To automate this, add the following alias to your $HOME/.bashrc:
alias phpunit="/usr/bin/php -dextension=/usr/lib64/php/modules/xdebug.so /usr/bin/phpunit"
It was surprisingly hard to figure this out, hope it helps someone!
