• Command - (TestCase)
• ConcreteCommand - (VectorTest)
• Client - (TestRunner)
• Invoker - (TestRunner)
• Receiver - your code being tested (Vector)

public interface Test {

	/**
	 * Runs a test and collects its result in a TestResult instance.
	 */
	public abstract void run(TestResult result);

}        

public abstract class TestCase extends Assert implements Test {
 
       /**
	 * Runs the test case and collects the results in TestResult.
	 */
	public void run(TestResult result) {
		result.run(this);
	}

}
