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

Constructs a new set of tests.

Parameters:

name - the name of the tests.

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

Returns the tests as a test suite.

 public  void testCloning() 
{
        WaterfallBarRenderer r1 = new WaterfallBarRenderer();
        WaterfallBarRenderer r2 = null;
        try {
            r2 = (WaterfallBarRenderer) r1.clone();
        }
        catch (CloneNotSupportedException e) {
            System.err.println("Failed to clone.");
        }
        assertTrue(r1 != r2);
        assertTrue(r1.getClass() == r2.getClass());
        assertTrue(r1.equals(r2));
        // quick check for independence
        r1.setFirstBarPaint(Color.yellow);
        assertFalse(r1.equals(r2));
        r2.setFirstBarPaint(Color.yellow);
        assertTrue(r1.equals(r2));
}

Confirm that cloning works.

 public  void testEquals() 
{
        WaterfallBarRenderer r1 = new WaterfallBarRenderer();
        WaterfallBarRenderer r2 = new WaterfallBarRenderer();
        assertEquals(r1, r2);
        // firstBarPaint;
        r1.setFirstBarPaint(Color.cyan);
        assertFalse(r1.equals(r2));
        r2.setFirstBarPaint(Color.cyan);
        assertTrue(r1.equals(r2));
        // lastBarPaint;
        r1.setLastBarPaint(Color.cyan);
        assertFalse(r1.equals(r2));
        r2.setLastBarPaint(Color.cyan);
        assertTrue(r1.equals(r2));
        // positiveBarPaint;
        r1.setPositiveBarPaint(Color.cyan);
        assertFalse(r1.equals(r2));
        r2.setPositiveBarPaint(Color.cyan);
        assertTrue(r1.equals(r2));
        //private Paint negativeBarPaint;
        r1.setNegativeBarPaint(Color.cyan);
        assertFalse(r1.equals(r2));
        r2.setNegativeBarPaint(Color.cyan);
        assertTrue(r1.equals(r2));
}

Check that the equals() method distinguishes all fields.

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

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