PHPUnit Badness

<?php

namespace app\tests;

use app\lib\Math;

class MathTest extends \lithium\test\Unit {

    public function testMin() {
        $result = Math::min([1, 2, 3]);
        $this->assertEqual(1, $result);
    }

    public function testMax() {
        $result = Math::max([1, 2, 3]);
        $this->assertEqual(3, $result);
    }
}
