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

Constructs a new set of tests.

Parameters:

name - the name of the tests.

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

Returns the tests as a test suite.

 public  void testCloning() 
{
        XYBarRenderer r1 = new XYBarRenderer();
        XYBarRenderer r2 = null;
        try {
            r2 = (XYBarRenderer) 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() 
{
        // default instances
        XYBarRenderer r1 = new XYBarRenderer();
        XYBarRenderer r2 = new XYBarRenderer();

        assertTrue(r2.equals(r1));
        // setBase()
        r1.setBase(1.0);
        assertFalse(r1.equals(r2));
        r2.setBase(1.0);
        assertTrue(r1.equals(r2));
        // setUseYInterval
        r1.setUseYInterval(!r1.getUseYInterval());
        assertFalse(r1.equals(r2));
        r2.setUseYInterval(!r2.getUseYInterval());
        assertTrue(r1.equals(r2));
        // setMargin()
        r1.setMargin(0.10);
        assertFalse(r1.equals(r2));
        r2.setMargin(0.10);
        assertTrue(r1.equals(r2));
        // setDrawBarOutline()
        r1.setDrawBarOutline(!r1.isDrawBarOutline());
        assertFalse(r1.equals(r2));
        r2.setDrawBarOutline(!r2.isDrawBarOutline());
        assertTrue(r1.equals(r2));
        // setGradientPaintTransformer()
        r1.setGradientPaintTransformer(
            new StandardGradientPaintTransformer(
                GradientPaintTransformType.CENTER_HORIZONTAL
            )
        );
        assertFalse(r1.equals(r2));
        r2.setGradientPaintTransformer(
            new StandardGradientPaintTransformer(
                GradientPaintTransformType.CENTER_HORIZONTAL
            )
        );
        assertTrue(r1.equals(r2));
        // legendBar
        r1.setLegendBar(new Rectangle2D.Double(1.0, 2.0, 3.0, 4.0));
        assertFalse(r1.equals(r2));
        r2.setLegendBar(new Rectangle2D.Double(1.0, 2.0, 3.0, 4.0));
        assertTrue(r1.equals(r2));
}

Test that the equals() method distinguishes all fields.

 public  void testFindDomainBounds() 
{
        XYSeriesCollection dataset 
            = RendererXYPackageTests.createTestXYSeriesCollection();
        JFreeChart chart = ChartFactory.createXYBarChart(
            "Test Chart", "X", false, "Y", dataset, 
            PlotOrientation.VERTICAL, false, false, false
        );
        XYPlot plot = (XYPlot) chart.getPlot();
        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 testHashcode() 
{
        XYBarRenderer r1 = new XYBarRenderer();
        XYBarRenderer r2 = new XYBarRenderer();
        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() 
{
        XYBarRenderer r1 = new XYBarRenderer();
        XYBarRenderer 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 = (XYBarRenderer) in.readObject();
            in.close();
        }
        catch (Exception e) {
            System.out.println(e.toString());
        }
        assertEquals(r1, r2);
}

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