PHPUnit_Framework_Exception: PHPUnit_Framework_TestCase::$name must not be null

Question

I am developing on a vagrant box which was custom built to serve the purpose. My PHPUnit version is 5.2.12 and Laravel version is 5.2.22.

When I am executing phpunit command, I get the following errors:

PHPUnit_Framework_Exception: PHPUnit_Framework_TestCase::$name must not be null.

Code

Below is my phpunit.xml content:

<?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="true"
         stopOnFailure="false"
         stderr="true">

        <testsuite name="Application Test Suite">
            <directory>./tests/</directory>
        </testsuite>
    </testsuites>
    <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>

So basically the problem was with overwritten __construct method:

class TestCase extends Illuminate\Foundation\Testing\TestCase
{
    public function __construct() 
    {
        //some code which should not be there
    }
}

The exception has gone after removing the constructor.
