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().

    $this->Graph->setDirected(true);
    $graph = &$this->Graph;

  <TR><TD PORT="here" BGCOLOR="lightblue">qualifier</TD></TR>
</TABLE>'),
     )));

    // Note: subgraph was created after some of its children in Image_GraphViz,
    // but Grafizzi lets you only add to existing elements, so it is created
    // earlier in this test.

      new Attribute($dic, 'title', ''),
