Laravel 5: PHPUnit and no code coverage driver ava

问题:

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"

     convertWarningsToExceptions="true"
     processIsolation="false"
     stopOnFailure="false">

        <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

回答2:

Update for anyone else stuck;

pecl install xdebug

回答3:

Update for PHP 7.1

xdebug is essential for code lookup and coverage , so xdebug is must to be installed or enabled in test environment. xdebug in production environment is not suggestible, it will affect performance if you turned on

brew install php71-xdebug

回答4:

As other developers answered, you need to install PHP Xdebug but I want to add new recommend for the developers who are using homestead by default have Xdebug (but it is off) and you can make it ON or OFF

If you want to make it on use below command in homestead

#for on :
xon

#for off:
xoff

Then check php -v and you will see Xdebug in the detail box

回答5:

For windows users:

1) download xdebug

2) rename the file to debug.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

回答6:

If you run phpunit inside a vagrant box then you don't need to install xdebug in local and homestead comes with xdebug install automatically. only needs to link homestead xdebug.ini file

Here is the step that worked for me:

cd ~/homestead/REPLACE THIS WITH YOUR HOMESTEAD FOLDER IN LOCAL //
vagrant ssh

sudo ln -s /etc/php/7.2/fpm/conf.d/20-xdebug.ini /etc/php/7.2/cli/conf.d/

In the above command if your running 7.3 or 7.1 then replace it based on your php version
