SSH框架学习（十、Junit+GroboUtils进行多线程测试）

Junit4不能模拟多线程的情况，需要其他支持，我用的是GroboUtils，最新版本5，下载地址：​​http://groboutils.sourceforge.net/downloads.html​​

GroboUtils测试的代码是用网上抄来的，来源：​​http://www.coderli.com/multi-thread-junit-grobountils​​

UserDAOImplTest的代码

package demo.myssh.dao.impl;

import net.sourceforge.groboutils.junit.v1.MultiThreadedTestRunner;
import net.sourceforge.groboutils.junit.v1.TestRunnable;
import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.test.annotation.Repeat;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.*;
import demo.myssh.dao.IUserDAO;
import demo.myssh.model.User;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({ "file:WebRoot/WEB-INF/applicationContext.xml" })
public class UserDAOImplTest {

  @Autowired
  @Qualifier("iUserDAO")
  private IUserDAO userDao;

  @Test
  @Repeat(2)
  public void MultiRequestsTest() {
    // 构造一个Runner
    TestRunnable runner = new TestRunnable() {
      @Override
      public void runTest() throws Throwable {
        // 测试内容
        // System.out.println("a");
        userDao.save(new User("aa", "bb", "cc"));
      }
    };
    int runnerCount = 2;
    // Rnner数组，相当于并发多少个。
    TestRunnable[] trs = new TestRunnable[runnerCount];
    for (int i = 0; i < runnerCount; i++) {
      trs[i] = runner;
    }
    // 用于执行多线程测试用例的Runner，将前面定义的单个Runner组成的数组传入
    MultiThreadedTestRunner mttr = new MultiThreadedTestRunner(trs);
    try {
      // 开发并发执行数组里定义的内容
      mttr.runTestRunnables();
    } catch (Throwable e) {
      e.printStackTrace();
    }
  }
}
