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

Constructs a new set of tests.

Parameters:

name - the name of the tests.

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

Returns the tests as a test suite.

 public  void testCloning() 
{
        XYDifferenceRenderer r1 
            = new XYDifferenceRenderer(Color.red, Color.blue, false);
        XYDifferenceRenderer r2 = null;
        try {
            r2 = (XYDifferenceRenderer) 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() 
{
        XYDifferenceRenderer r1 = new XYDifferenceRenderer(
                Color.red, Color.blue, false);
        XYDifferenceRenderer r2 = new XYDifferenceRenderer(
                Color.red, Color.blue, false);
        assertEquals(r1, r2);
        // positive paint
        r1 = new XYDifferenceRenderer(Color.green, Color.blue, false);
        assertFalse(r1.equals(r2));
        r2 = new XYDifferenceRenderer(Color.green, Color.blue, false);
        assertTrue(r1.equals(r2));
        // negative paint
        r1 = new XYDifferenceRenderer(Color.green, Color.yellow, false);
        assertFalse(r1.equals(r2));
        r2 = new XYDifferenceRenderer(Color.green, Color.yellow, false);
        assertTrue(r1.equals(r2));
        // shapesVisible
        r1 = new XYDifferenceRenderer(Color.green, Color.yellow, true);
        assertFalse(r1.equals(r2));
        r2 = new XYDifferenceRenderer(Color.green, Color.yellow, true);
        assertTrue(r1.equals(r2));
        // legendLine
        r1.setLegendLine(new Line2D.Double(1.0, 2.0, 3.0, 4.0));
        assertFalse(r1.equals(r2));
        r2.setLegendLine(new Line2D.Double(1.0, 2.0, 3.0, 4.0));
        assertTrue(r1.equals(r2));
        assertFalse(r1.equals(null));
}

Check that the equals() method distinguishes all fields.

 public  void testHashcode() 
{
        XYDifferenceRenderer r1 
            = new XYDifferenceRenderer(Color.red, Color.blue, false);
        XYDifferenceRenderer r2 
            = new XYDifferenceRenderer(Color.red, Color.blue, false);
        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() 
{
        XYDifferenceRenderer r1 
            = new XYDifferenceRenderer(Color.red, Color.blue, false);
        XYDifferenceRenderer 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 = (XYDifferenceRenderer) in.readObject();
            in.close();
        }
        catch (Exception e) {
            System.out.println(e.toString());
        }
        assertEquals(r1, r2);
}

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