Mapping test methods to a TPTP JUnit test

From the Java class, TPTP JUnit Test automatically identifies methods whose names begin with 'test' and maps these onto Test Methods. For example, the source of the class SimpleTest is as follows:

package junit.samples;
import junit.framework.*;
* Some simple tests.
public class SimpleTest extends TestCase 
	protected int fValue1;
	protected int fValue2;

	protected void setUp() 
	fValue1= 2;
	fValue2= 3;

	public static Test suite() 
	* the type safe way
	TestSuite suite= new TestSuite();
	suite.addTest(new SimpleTest("add") 
	protected void runTest() { testAdd(); }

	suite.addTest(new SimpleTest("testDivideByZero") 
	protected void runTest() { testDivideByZero(); }

	return suite;
	* the dynamic way

	return new TestSuite(SimpleTest.class);

	public void testAdd() 
		double result= fValue1 + fValue2;
		// forced failure result == 5
		assertTrue(result == 6);

	public void testDivideByZero() 
		int zero= 0;
		int result= 8/zero;

	public void testEquals() 
		assertEquals(12, 12);
		assertEquals(12L, 12L);
		assertEquals(new Long(12), new Long(12));
		assertEquals("Size", 12, 13);
		assertEquals("Capacity", 12.0, 11.99, 0.0);

	public static void main (String[] args) 

There are 3 methods whose names begin with 'test': testAdd, testDivideByZero, and testEquals. These methods are listed in the Test Methods pane of the Overview tab.

Note that, if the user adds a test method using the test editor, a new method will be added to the code.

Also, a requirement for being able to run a JUnit class in TPTP is that this class must have a static "Test suite()" method (which is a standard JUnit practice). When the behavior check box is unchecked, this suite() method and its content are automatically generated (and updated when the user saves the test using the test editor). When the check box is checked, the user has to implement this suite() method.

To learn about editing methods on the test, read the JUnit Test Editor topic.
