Allow multiple directories for code coverage

I have two directories that I need to check code coverage for. However, there doesn't seem to be a way to include both directories. Attempting to do so causes some kind of auto-loading error.

Example config:

<?xml version="1.0" encoding="UTF-8"?>
<phpunit backupGlobals="false"
         backupStaticAttributes="false"
         bootstrap="vendor/autoload.php"
         colors="true"
         convertErrorsToExceptions="true"
         convertNoticesToExceptions="true"
         convertWarningsToExceptions="true"
         processIsolation="false"
         stopOnFailure="false">
    <testsuites>
        <testsuite name="Unit">
            <directory suffix="Test.php">./tests/Unit</directory>
        </testsuite>

        <testsuite name="Feature">
            <directory suffix="Test.php">./tests/Feature</directory>
        </testsuite>

        <testsuite name="Modules">
            <directory suffix="Test.php">./modules</directory>
        </testsuite>
    </testsuites>
    <filter>
        <whitelist processUncoveredFilesFromWhitelist="true">
            <directory suffix=".php">./app</directory>
            <directory suffix=".php">./modules</directory>
        </whitelist>
    </filter>
    <logging>
        <log type="coverage-html" target="./tests/report" lowUpperBound="35"
             highLowerBound="70"/>
    </logging>
    <php>
        <env name="APP_ENV" value="testing"/>
        <env name="BCRYPT_ROUNDS" value="4"/>
        <env name="CACHE_DRIVER" value="array"/>
        <env name="SESSION_DRIVER" value="array"/>
        <env name="QUEUE_CONNECTION" value="sync"/>
        <env name="MAIL_DRIVER" value="array"/>
    </php>
</phpunit>

Notice the two directories ./app and ./modules. The ./modules line is causing errors.

Whitelisting multiple directories for code coverage works just fine. Do note, though, that all whitelisted files will be included because you set processUncoveredFilesFromWhitelist="true". This is likely the cause for the problem you are experiencing (because you likely include files that not only contain class/interface/trait declarations).
