springboot 单元测试

在项目中，经常会需要测试程序中的某个功能或者某个方法，来判断程序的正确性和性能。如何在spring boot项目中完成单元测试呢。

首先，需要有必备的工具包。spring-boot测试工具包org.springframework.bootspring-boot-starter-test此包中有很多的测试包。

第二步，导入相关的注解。@RunWith(SpringRunner.class)@SpringBootTest(classes = SkynetApplication.class)@EnableAutoConfiguration @RunWith就是一个运行器，可以指定用哪个测试框架运行，@RunWith(JUnit4.class)就是指用JUnit4来运行@RunWith(SpringJUnit4ClassRunner.class)使用了Spring的SpringJUnit4ClassRunner，以便在测试开始的时候自动创建Spring的应用上下文。其他的想创建spring容器的话，就得子啊web.xml配置classloder。注解了@RunWith就可以直接使用spring容器，直接使用@Test注解，不用启动spring容器；这里springboot选择的是@RunWith(SpringRunner.class）；@SpringBootTest(classes = SkynetApplication.class)用来指定配置；@EnableAutoConfiguration是的程序的配置可以自动的注入容器中。代码如下：

TbTest tbTest =newTbTest();

Random random =newRandom();

longc = System.currentTimeMillis();

for(inti =0; i <10000; i++){

tbTest.setAge(random.nextInt(100));

tbTest.setBrithday(DateUtil.parseDate(random.nextInt(2017)+"-"+random.nextInt(12)

+"-"+random.nextInt(30)+" "+random.nextInt(24)+":"+random.nextInt(60)+":"+random.nextInt(60),"yyyy-MM-dd HH:mm:ss"));

tbTest.setHigh(random.nextInt(200));

tbTest.setIsboy((short)random.nextInt(2));

tbTest.setName(f[random.nextInt(f.length-1)]+s[random.nextInt(s.length-1)]);

tbTest.setSchool("皖西学院"+random.nextInt(10000));

tbTest.setWigth(random.nextInt(200));

tbTestMapper.insertSelective(tbTest);

}

System.out.println("耗时："+(System.currentTimeMillis()-c)/1000);

}

publicString getName(){

Random random =newRandom(100);

String name;
