wicket test paginas con parametros

por ejemplo si tenemos

public class AlbumPage extends WebPage{
private final Album album;

public AlbumPage(Album album) {
this.album = album;
}
}

el test seria

//creado asi por fluent (http://en.wikipedia.org/wiki/Fluent_interface#Java )
final Album mockAlbum = new Album().setArtist( new Artist().setName("Pepe Argento")).setName("el disco de pp");

public void testRenderThePage() {
//con una clase anonima, estamos sobreescribiendo el metodo getTestPage(), para porder invocar a la pagina con el constructor
//(otra bondad de las clases anonimas =D )
getTesterApplication().startPage(new ITestPageSource() {
private static final long serialVersionUID = 1L;
public Page getTestPage() {
      return new AlbumPage(mockAlbum);
 }
});

getTesterApplication().assertRenderedPage(AlbumPage.class);

el error que da si queremos usar startPage(MiPagina.class )
