junit4按顺序执行test方法

junit在4.6版本以后，支持指定test方法运行顺序的标签。包含以下options：

/** Sorts the test methods by the method name, in lexicographic order */
NAME_ASCENDING(MethodSorter.NAME_ASCENDING),

/** Leaves the test methods in the order returned by the JVM. Note that the order from the JVM my vary from run to run */
JVM(null),

/** Sorts the test methods in a deterministic, but not predictable, order */
DEFAULT(MethodSorter.DEFAULT);

用法：

import static org.junit.Assert.*;

import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.junit.FixMethodOrder;
import org.junit.runners.MethodSorters;

@FixMethodOrder(MethodSorters.JVM)
public class Myt {

	@Before
	public void setUp() throws Exception {
	}

	@After
	public void tearDown() throws Exception {
	}

	@Test
	public void testA() {
		System.out.println("1");
	}

	@Test
	public void testBB() {
		System.out.println("2");
	}
	
	@Test
	public void testCC() {
		System.out.println("3");
	}
	
	@Test
	public void testDD() {
		System.out.println("4");
	}

}

输出结果是：

2

1

3

4
