/**
 * A test case defines the fixture to run multiple tests. To define a test case<br/>
 * <ol>
 *   <li>implement a subclass of <code>TestCase</code></li>
 *   <li>define instance variables that store the state of the fixture</li>
 *   <li>initialize the fixture state by overriding {@link #setUp()}</li>
 *   <li>clean-up after a test by overriding {@link #tearDown()}.</li>
 * </ol>
 * Each test runs in its own fixture so there
 * can be no side effects among test runs.
 * Here is an example:
 * <pre>
 * public class MathTest extends TestCase {
 *    protected double fValue1;
 *    protected double fValue2;
 *
 *    protected void setUp() {
 *       fValue1= 2.0;
 *       fValue2= 3.0;
 *    }
 * }
 * </pre>
 *
 * For each test implement a method which interacts
 * with the fixture. Verify the expected results with assertions specified
 * by calling {@link junit.framework.Assert#assertTrue(String, boolean)} with a boolean.
 * <pre>
 *    public void testAdd() {
 *       double result= fValue1 + fValue2;
 *       assertTrue(result == 5.0);
 *    }
 * </pre>
 *
 * Once the methods are defined you can run them. The framework supports
 * both a static type safe and more dynamic way to run a test.
 * In the static way you override the runTest method and define the method to
 * be invoked. A convenient way to do so is with an anonymous inner class.
 * <pre>
 * TestCase test= new MathTest("add") {
 *    public void runTest() {
 *       testAdd();
 *    }
 * };
 * test.run();
 * </pre>
 * The dynamic way uses reflection to implement {@link #runTest()}. It dynamically finds
 * and invokes a method.
 * In this case the name of the test case has to correspond to the test method
 * to be run.
 * <pre>
 * TestCase test= new MathTest("testAdd");
 * test.run();
 * </pre>
 *
 * The tests to be run can be collected into a TestSuite. JUnit provides
 * different <i>test runners</i> which can run a test suite and collect the results.
 * A test runner either expects a static method <code>suite</code> as the entry
 * point to get a test to run or it will extract the suite automatically.
 * <pre>
 * public static Test suite() {
 *    suite.addTest(new MathTest("testAdd"));
 *    suite.addTest(new MathTest("testDivideByZero"));
 *    return suite;
 * }
 * </pre>
 *
 * @see TestResult
 * @see TestSuite
