Laravel 5: PHPUnit and no code coverage driver available

Question

I would like to use PHPUnit to create code coverage reports. I have tried a lot of installation setups found on the web. But nothing seems to work out.

I use the latest version of Laravel 5 (>5.2) and PHPUnit v. 5.0.10. Further, I use MAMP on Mac OS X 10.9.5 running PHP 7.

When I run PHPUnit that is integrated in my Laravel distribution, I receive the following error.

$ vendor/bin/phpunit -v
PHPUnit 5.0.10 by Sebastian Bergmann and contributors.

Runtime:       PHP 7.0.0
Configuration: /Applications/MAMP/htdocs/myProject/phpunit.xml
Error:         No code coverage driver is available`

My composer file looks like:

"require-dev": {
    "fzaninotto/faker": "~1.4",
    "mockery/mockery": "0.9.*",
    "phpunit/phpunit": "5.0.*",
    "phpunit/php-code-coverage": "^3",
    "symfony/css-selector": "2.8.*|3.0.*",
    "symfony/dom-crawler": "2.8.*|3.0.*"
},

I have also tried the following command:

/Applications/MAMP/bin/php/php7.0.0/bin/phpdbg -qrr ../../../htdocs/myProject/vendor/bin/phpunit -v

This seems to set up the code coverage driver well, but it ends up in an exception:

$ /Applications/MAMP/bin/php/php7.0.0/bin/phpdbg -qrr ../../../htdocs/myProject/vendor/bin/phpunit -v
PHPUnit 5.0.10 by Sebastian Bergmann and contributors.

Runtime:       PHPDBG 7.0.0
Configuration: /Applications/MAMP/htdocs/myProject/phpunit.xml

[PHP Fatal error:  Uncaught ErrorException: include(/Applications/MAMP/htdocs/myProject/app/Exceptions/Handler.php): failed to open stream: Too many open files in /Applications/MAMP/htdocs/myProject/vendor/composer/ClassLoader.php:412
Stack trace:

The phpunit.xml looks as follows:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
     backupStaticAttributes="false"
     bootstrap="bootstrap/autoload.php"
     colors="true"
     convertErrorsToExceptions="true"
     convertNoticesToExceptions="true"
     convertWarningsToExceptions="true"
     processIsolation="false"
     stopOnFailure="false">
    <testsuites>
        <testsuite name="Application Test Suite">
            <directory>./tests/</directory>
        </testsuite>
    </testsuites>
    <logging>
      <log type="coverage-html" target="./tests/codeCoverage" charset="UTF-8"/>
    </logging>
    <filter>
        <whitelist>
            <directory suffix=".php">app/</directory>
        </whitelist>
    </filter>
    <php>
        <env name="APP_ENV" value="testing"/>
        <env name="CACHE_DRIVER" value="array"/>
        <env name="SESSION_DRIVER" value="array"/>
        <env name="QUEUE_DRIVER" value="sync"/>
    </php>
</phpunit>

Is it possible to use PHPUnit that comes with the Laravel framework together with code coverage? How should I set it up and use it?

Thanks a lot for your help.

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
