Phpunit: define() + runInSeparateProcess = Constant already defined

[cweiske]

Two test cases, the first includes a file with a define() call. The second has a test that is run in a separate process. The define() call will be made twice, which I can't understand.

Happens with PHP 5.4.6, xdebug 2.2.1 and PHPUnit 3.7.18

Files

ATest.php:

<?php
require_once 'Define.php';
class ATest extends PHPUnit_Framework_TestCase
{
    public function testA2() {}
}
?>

BTest.php:

<?php
class BTest extends PHPUnit_Framework_TestCase
{
    /**
     * @runInSeparateProcess
     */
    public function testB() {}
}
?>

Define.php:

<?php
define('FOO', 1);
?>

Results:

This is a duplicate of #314. If possible, you can use @preserveGlobalState disabled as a workaround.
