Permissions error with "//proc/tty/driver" in PHPUnit and Jenkins? - php

Question

I am attempting to run a build on Jenkins running Ubuntu 14.04. My PHPUnit is crashing with the below error message, but there doesn't seem to much out there regarding this error. My xdebug appears to be loading correctly. I am running PHPUnit v4.8.10.
When I try to run phpunit via the command line directly, it just hangs and doesn't return. What am I missing?
phpunit:
[phpunit] PHP Fatal error: Uncaught exception 'UnexpectedValueException' with message 'RecursiveDirectoryIterator::__construct(//proc/tty/driver): failed to open dir: Permission denied' in /var/lib/jenkins/jobs/Some other job/workspace/vendor/phpunit/php-file-iterator/src/Factory.php:66

The problem was with my whitelisting inside my phpunit.xml. As you can see in the <directory> tag, I was telling my code coverage to start at the root of the server! Which is how it ended up looking through my sockets and getting caught somewhere it shouldn't have been.
To resolve this, change the <directory suffix=".php">/</directory> below to <directory suffix=".php">./</directory> so the code coverage only looks through your project directory.
The old filter:
<filter>
<whitelist addUncoveredFilesFromWhitelist="true">
<directory suffix=".php">/</directory>
<exclude>
<file>bootstrap/autoload.php</file>
</exclude>
</whitelist>
</filter>
