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

Constructs a new set of tests.

Parameters:

name - the name of the tests.

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

Returns the tests as a test suite.

 public  void testEquals() 
{
        DefaultCategoryDataset d1 = new DefaultCategoryDataset();
        d1.setValue(23.4, "R1", "C1");
        DefaultCategoryDataset d2 = new DefaultCategoryDataset();
        d2.setValue(23.4, "R1", "C1");
        assertTrue(d1.equals(d2));
        assertTrue(d2.equals(d1));
        d1.setValue(36.5, "R1", "C2");
        assertFalse(d1.equals(d2));
        d2.setValue(36.5, "R1", "C2");
        assertTrue(d1.equals(d2));
        d1.setValue(null, "R1", "C1");
        assertFalse(d1.equals(d2));
        d2.setValue(null, "R1", "C1");
        assertTrue(d1.equals(d2));
}

Confirm that the equals method can distinguish all the required fields.

 public  void testGetColumnCount() 
{
        DefaultCategoryDataset d = new DefaultCategoryDataset();
        assertTrue(d.getColumnCount() == 0);
        d.addValue(1.0, "R1", "C1");
        assertTrue(d.getColumnCount() == 1);
        d.addValue(1.0, "R1", "C2");
        assertTrue(d.getColumnCount() == 2);
        d.addValue(2.0, "R1", "C2");
        assertTrue(d.getColumnCount() == 2);
        // a column of all null values is still counted...
        d.setValue(null, "R1", "C2");
        assertTrue(d.getColumnCount() == 2);
}

Some tests for the getColumnCount() method.

 public  void testGetRowCount() 
{
        DefaultCategoryDataset d = new DefaultCategoryDataset();
        assertTrue(d.getRowCount() == 0);
        d.addValue(1.0, "R1", "C1");
        assertTrue(d.getRowCount() == 1);
        d.addValue(1.0, "R2", "C1");
        assertTrue(d.getRowCount() == 2);
        d.addValue(2.0, "R2", "C1");
        assertTrue(d.getRowCount() == 2);
        // a row of all null values is still counted...
        d.setValue(null, "R2", "C1");
        assertTrue(d.getRowCount() == 2);
}

Some tests for the getRowCount() method.

 public  void testSerialization() 
{
        DefaultCategoryDataset d1 = new DefaultCategoryDataset();
        d1.setValue(23.4, "R1", "C1");
        DefaultCategoryDataset d2 = null;
        try {
            ByteArrayOutputStream buffer = new ByteArrayOutputStream();
            ObjectOutput out = new ObjectOutputStream(buffer);
            out.writeObject(d1);
            out.close();
            ObjectInput in = new ObjectInputStream(
                new ByteArrayInputStream(buffer.toByteArray())
            );
            d2 = (DefaultCategoryDataset) in.readObject();
            in.close();
        }
        catch (Exception e) {
            System.out.println(e.toString());
        }
        assertEquals(d1, d2);
}
