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

Constructs a new set of tests.

Parameters:

name - the name of the tests.

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

Returns the tests as a test suite.

 public  void testCloning() 
{
        StackedXYBarRenderer r1 = new StackedXYBarRenderer();
        StackedXYBarRenderer r2 = null;
        try {
            r2 = (StackedXYBarRenderer) r1.clone();
        }
        catch (CloneNotSupportedException e) {
            System.err.println("Failed to clone.");
        }
        assertTrue(r1 != r2);
        assertTrue(r1.getClass() == r2.getClass());
        assertTrue(r1.equals(r2));
}

Confirm that cloning works.

 public  void testEquals() 
{
        StackedXYBarRenderer r1 = new StackedXYBarRenderer();
        StackedXYBarRenderer r2 = new StackedXYBarRenderer();
        assertTrue(r1.equals(r2));
        assertTrue(r2.equals(r1));
}

Test that the equals() method distinguishes all fields.

 public  void testFindDomainBounds() 
{
        TableXYDataset dataset 
            = RendererXYPackageTests.createTestTableXYDataset();
        JFreeChart chart = ChartFactory.createStackedXYAreaChart(
            "Test Chart", "X", "Y", dataset, 
            PlotOrientation.VERTICAL, false, false, false
        );
        XYPlot plot = (XYPlot) chart.getPlot();
        plot.setRenderer(new StackedXYBarRenderer());
        NumberAxis domainAxis = (NumberAxis) plot.getDomainAxis();
        domainAxis.setAutoRangeIncludesZero(false);
        Range bounds = domainAxis.getRange();
        assertFalse(bounds.contains(0.3));
        assertTrue(bounds.contains(0.5));
        assertTrue(bounds.contains(2.5));
        assertFalse(bounds.contains(2.8));
}

Check that the renderer is calculating the domain bounds correctly.

 public  void testFindRangeBounds() 
{
        TableXYDataset dataset 
            = RendererXYPackageTests.createTestTableXYDataset();
        JFreeChart chart = ChartFactory.createStackedXYAreaChart(
            "Test Chart", "X", "Y", dataset, 
            PlotOrientation.VERTICAL, false, false, false
        );
        XYPlot plot = (XYPlot) chart.getPlot();
        plot.setRenderer(new StackedXYBarRenderer());
        NumberAxis rangeAxis = (NumberAxis) plot.getRangeAxis();
        Range bounds = rangeAxis.getRange();
        assertTrue(bounds.contains(6.0));
        assertTrue(bounds.contains(8.0));
}

Check that the renderer is calculating the range bounds correctly.

 public  void testHashcode() 
{
        StackedXYBarRenderer r1 = new StackedXYBarRenderer();
        StackedXYBarRenderer r2 = new StackedXYBarRenderer();
        assertTrue(r1.equals(r2));
        int h1 = r1.hashCode();
        int h2 = r2.hashCode();
        assertEquals(h1, h2);
}

Two objects that are equal are required to return the same hashCode.

 public  void testSerialization() 
{
        StackedXYBarRenderer r1 = new StackedXYBarRenderer();
        StackedXYBarRenderer r2 = null;
        try {
            ByteArrayOutputStream buffer = new ByteArrayOutputStream();
            ObjectOutput out = new ObjectOutputStream(buffer);
            out.writeObject(r1);
            out.close();
            ObjectInput in = new ObjectInputStream(
                new ByteArrayInputStream(buffer.toByteArray())
            );
            r2 = (StackedXYBarRenderer) in.readObject();
            in.close();
        }
        catch (Exception e) {
            System.out.println(e.toString());
        }
        assertEquals(r1, r2);
}

Serialize an instance, restore it, and check for equality.
