use NoRegression\PHPUnit\Comparator\Callables\IsDateTime;
use NoRegression\PHPUnit\Comparator\Callables\IsUuid;
use NoRegression\PHPUnit\Comparator\Callables\IsPasswordHashFor;

class ExampleTest extends \PHPUnit_Framework_TestCase
{
    use CallableComparatorTrait;

    public function setUp()
    {
        parent::setUp();
        $this->setupCallableComparator();
    }

    public function tearDown()
    {
