junit 4.11中三个新功能

junit 4.11中两个新增的功效，首先是注解中可以参数化，比如

import static org.junit.Assert.assertEquals;
 
import java.util.Arrays;
 
import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.junit.runners.Parameterized.Parameters;
 
@RunWith(Parameterized.class)
public class ParameterizedTest {
	@Parameters(name = "Run #{index}: {0}^2={1}")
	public static Iterable<Object[]> data() {
		return Arrays.asList(new Object[][] { { 1, 1 }, { 2, 4 }, { 3, 9 },
				{ 4, 16 }, { 5, 25 } });
	}
 
	private final int input;
	private final int resultExpected;
 
	public ParameterizedTest(final int input, final int result) {
		this.input = input;
		this.resultExpected = result;
	}
 
	@Test
	public void testUserMapping() {
		Calculator calc = new Calculator();
		assertEquals(resultExpected, calc.square(input));
	}
