It seems like you call parent on a different method (setUpExtended() instead of setUp()). Are you sure this is correct? If so, you might want to change this to $this->setUpExtended().

    $g = $this->Graph;
    $dic = $this->dic;
    $g->setDirected(true);
    $letters = array('G', 'E', 'B', 'F', 'R', 'H', 'Y', 'A', 'C');

    $nodeShape = new Attribute($dic, 'shape', 'record');
    $nodes = array();
    foreach ($letters as $offset => $letter) {
      $g->addChild($nodes[$offset] = new Node($dic, "node$offset", array(
        $nodeShape,
        new Attribute($dic, 'label', "<f0> |<f1> $letter|<f2> "),
      )));
    }

    $edgeAttributes = array();
    $g->addChild(new Edge($dic, $nodes[0], $nodes[4], $edgeAttributes, 'f2', 'f1'));
    $g->addChild(new Edge($dic, $nodes[0], $nodes[1], $edgeAttributes, 'f0', 'f1'));
    $g->addChild(new Edge($dic, $nodes[1], $nodes[2], $edgeAttributes, 'f0', 'f1'));
    $g->addChild(new Edge($dic, $nodes[1], $nodes[3], $edgeAttributes, 'f2', 'f1'));
    $g->addChild(new Edge($dic, $nodes[2], $nodes[8], $edgeAttributes, 'f2', 'f1'));
    $g->addChild(new Edge($dic, $nodes[2], $nodes[7], $edgeAttributes, 'f0', 'f1'));
