Java Web并发单元测试摘记(1)
大的
web项目开发和运行环境都在服务器容器中进行为主,包括调试过程,也都是单例进过Web触发进行
测试。在Web项目中设计使用Spring、hibernate、JBPM工作流、ehcache各种框架或组件。这些东西在一起配置好一个有效的、覆盖所有环境的
单元测试用例也比较复杂。所有配置好一个可用有效的单元测试环境十分必要。并且面对单元测试对并发要求的不支持,还得加入必要的并发测试组件,满足测试全面系统
白盒测试要求。
这里总结几种有效的配置单元测试方式:
1、直接使用Junit4组件,进行简单单元测试,在setUp()中初始化各种测试环境如下:
@Override
protected void setUp() throws Exception {
super.setUp();
String[] paths = { "classpath:applicationContext.xml" };
ApplicationContext ctx = new ClassPathXmlApplicationContext(paths);
SpringContextListener.setApplicationContext(ctx);
// ############模拟servlet容器启动,手动更改配置文件路径
Constant.CURRENT_PROJECT_PATH = "src/";
// ############直接容器中获取bean
userManager = (UserManager) ctx.getBean("userManager");
userService = (UserService) ctx.getBean("userService");
}
|
2、使用Sprint-test.jar框架,支持事务可注解方式启动的单元测试:
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:applicationContext.xml")
@TransactionConfiguration(transactionManager="transactionManager",defaultRollback=false) //true将会回滚所有操作,默认没有该注解为回滚
public class JBPMProcessTest2 extends AbstractTransactionalJUnit4SpringContextTests{
|
以上都只能暂时支持简单功能的单元测试。但是要测试并发和压力等。需要加入一个常用的框架,支持在单元测试中注入多线程和并发。
具体参见:http://blog.csdn.net/zhangyaoming2004/article/details/7619489 下面附有Jar包下载 http://yunpan.cn/QUtVay66VnU4T
我们具体使用的功能不是很多,这些并发测试可以嵌入到上面两种单元测试方式中:如下:

init();

}
/*

*/
@Override
public void runTest() throws Throwable {
// TODO Auto-generated method stub
// ########################模拟当前任务该报表期任务上报
//保存数据
ExcelReportResult result = taskLogicService.reportData(reportMap, user, invokeSource);
excelReportLogicService.saveData(result);
System.out.println("报表期为:"+this.bbq+"已上报");
}
}

真实环境并发和压力测试不仅仅是在多个线程同时启动在测,还可能是增量式压力测试。这些还是要封装好和处理好。
