很多情况下,写了一堆的test case,希望某一些test case必须在某个test case之后执行。比如,测试某一个Dao代码,希望添加的case在前面,然后是修改或者查询,后才是删除,以前的做法把所有的方法都集中到某一个方法去执行,一个个罗列好,比较麻烦。比较幸福的事情是JUnit4.11之后提供了MethodSorters,可以有三种方式对test执行顺序进行指定,如下:
/**
* Sorts the test methods by the method name, in lexicographic order, with {@link Method#toString()} used as a tiebreaker
*/
NAME_ASCENDING(MethodSorter.NAME_ASCENDING),
/**
* Leaves the test methods in the order returned by the JVM. Note that the order from the JVM may vary from run to run
*/
JVM(null),
/**
* Sorts the test methods in a deterministic, but not predictable, order
*/
DEFAULT(MethodSorter.DEFAULT);
可以小试牛刀一下:
使用DEFAULT方式:
package com.netease.test.junit;
import org.apache.log4j.Logger;
import org.junit.FixMethodOrder;
import org.junit.Test;
import org.junit.runners.MethodSorters;
/**
* User: hzwangxx
* Date: 14-3-31
* Time: 15:35
*/
@FixMethodOrder(MethodSorters.DEFAULT)
public class TestOrder {
private static final Logger LOG = Logger.getLogger(TestOrder.class);
@Test
public void testFirst() throws Exception {
LOG.info("------1--------");
}
@Test
public void testSecond() throws Exception {
LOG.info("------2--------");
}
@Test
public void testThird() throws Exception {
LOG.info("------3--------");
}
}
