Laravel 5: PHPUnit and no code coverage driver available

It seems like you are missing the Xdebug extension. If you're using homebrew you can install it like:

brew install php70-xdebug

After that, don't forget to edit your php.ini file to enable the extension.

php -i | grep xdebug

After checking that xdebug is enabled you should be able to do code coverage

For windows users:

1) Download xdebug

2) Rename the file to _php_xdebug.dll_ and copy the file to the ext folder in your php installation e.g C:\Program Files (x86)\php\ext

3) Open your php.ini file. For me it’s available at C:\Program Files (x86)\php\php.ini.

4) Paste the below code at the bottom of the file.

zend_extension = php_xdebug.dll
xdebug.remote_enable = 1
xdebug.remote_handler = dbgp
xdebug.remote_host = localhost
xdebug.remote_autostart = 1
xdebug.remote_port = 9000
xdebug.show_local_vars = 1

Update for anyone else stuck;

pecl install xdebug
