public StackedAreaChartTests(String name) 
{
        super(name);
}

Constructs a new set of tests.

Parameters:

name - the name of the tests.

 protected  void setUp() 
{
        this.chart = createChart();
}

Common test setup.

 public static Test suite() 
{
        return new TestSuite(StackedAreaChartTests.class);
}

Returns the tests as a test suite.

 public  void testDrawWithNullInfo() 
{
        boolean success = false;
        try {
            BufferedImage image = new BufferedImage(
                200 , 100, BufferedImage.TYPE_INT_RGB
            );
            Graphics2D g2 = image.createGraphics();
            this.chart.draw(
                g2, new Rectangle2D.Double(0, 0, 200, 100), null, null
            );
            g2.dispose();
            success = true;
        }
        catch (Exception e) {
          success = false;
        }
        assertTrue(success);
}

Draws the chart with a null info object to make sure that no exceptions are thrown (a problem that was occurring at one point).

 public  void testReplaceDataset() 
{
        // create a dataset...
        Number[][] data = new Integer[][]
            {{new Integer(-30), new Integer(-20)},
             {new Integer(-10), new Integer(10)},
             {new Integer(20), new Integer(30)}};
        CategoryDataset newData 
            = DatasetUtilities.createCategoryDataset("S", "C", data);
        LocalListener l = new LocalListener();
        this.chart.addChangeListener(l);
        this.chart.getCategoryPlot().setDataset(newData);
        assertEquals(true, l.flag);
        ValueAxis axis = this.chart.getCategoryPlot().getRangeAxis();
        Range range = axis.getRange();
        assertTrue("Expecting the lower bound of the range to be around -30: "
                    + range.getLowerBound(), range.getLowerBound() < = -30);
        assertTrue("Expecting the upper bound of the range to be around 30: "
                   + range.getUpperBound(), range.getUpperBound()  >= 30);
}

Replaces the dataset and checks that it has changed as expected.

 public  void testSetSeriesToolTipGenerator() 
{
        CategoryPlot plot = (CategoryPlot) this.chart.getPlot();
        CategoryItemRenderer renderer = plot.getRenderer();
        StandardCategoryToolTipGenerator tt
            = new StandardCategoryToolTipGenerator();
        renderer.setSeriesToolTipGenerator(0, tt);
        CategoryToolTipGenerator tt2 = renderer.getToolTipGenerator(0, 0);
        assertTrue(tt2 == tt);
}

Check that setting a tool tip generator for a series does override the default generator.

 public  void testSetSeriesURLGenerator() 
{
        CategoryPlot plot = (CategoryPlot) this.chart.getPlot();
        CategoryItemRenderer renderer = plot.getRenderer();
        StandardCategoryURLGenerator url1
            = new StandardCategoryURLGenerator();
        renderer.setSeriesItemURLGenerator(0, url1);
        CategoryURLGenerator url2 = renderer.getItemURLGenerator(0, 0);
        assertTrue(url2 == url1);
}

Check that setting a URL generator for a series does override the default generator.
