ClassMetadata

<?php
$class = Mockery::mock('Doctrine\ORM\ClassMetadata');

include '/mypath/doctrine/orm/lib/Doctrine/ORM/Query.php';
?>

Now I get the following error message:
  Fatal error: Cannot use Doctrine\ORM\Mapping\ClassMetadata as ClassMetadata because the name is already in use in Query.php on line 29
  
This line contains a namespace import:
  use Doctrine\ORM\Mapping\ClassMetadata;

When I mock the ClassMetadata with the correct namespace I don't get a error
<?php
$class = Mockery::mock('Doctrine\ORM\Mapping\ClassMetadata');

include '/mypath/doctrine/orm/lib/Doctrine/ORM/Query.php';
?>
