Currently :
<?php
$edit_links = $this->xpath('//a[@href=:href]', array(
':href'=> url('admin/structure/contact/manage/personal')
));
$this->assertTrue(empty($links), format_string('No link containing href %href found.',
array('%href'=> 'admin/structure/contact/manage/personal')
));
?>$links is never defined, so will always be empty.
