- 单元测试（一）——SpringBoot建立单元测试
- 单元测试（二）——Junit4+EasyMock建立单元测试
- 单元测试（三）——建立多线程单元测试
在Spring项目中，对于controller、service、dao各层都需要建立单元测试项。对应不同的分层，我们可以使用junit和mock不同的方式。然而有些情况会需要启动spring容器来测试业务逻辑在容器内能否正常运行，针对此情况可参考如下单元测试方式。
SpringBoot增加依赖
org.springframework.boot
spring-boot-starter-test
test
建立测试基类
- 新建JUnitBaseTest.java
package com.lucas.device;
import org.junit.After;
import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.context.web.WebAppConfiguration;
import org.springframework.util.StopWatch;
import lombok.extern.slf4j.Slf4j;
/**
*
*
* @author xubin
* @version 1.0
* @taskId
* @CreateDate 2018年9月27日
*/
@Slf4j
@RunWith(SpringRunner.class)
@SpringBootTest
@WebAppConfiguration
public class JUnitBaseTest {
/**
* sw 计时器
*/
public static StopWatch sw = null;
/**
* Description:
*
* @author xubin
* @taskId
* @throws java.lang.Exception
*/
@BeforeClass
public static void setUpBeforeClass() throws Exception {
sw = new StopWatch();
}
/**
* Description:
*
* @author xubin
* @taskId
* @throws java.lang.Exception
*/
@AfterClass
public static void tearDownAfterClass() throws Exception {
log.info("**************************************************************");
log.info("单元测试计时统计：{}", sw.prettyPrint());
log.info("**************************************************************");
}
/**
* Description:
*
* @author xubin
* @taskId
* @throws java.lang.Exception
*/
@Before
public void setUp() throws Exception {
log.info("开始测试-----------------");
}
/**
* Description:
*
* @author xubin
* @taskId
* @throws java.lang.Exception
*/
@After
public void tearDown() throws Exception {
sw.stop();
log.info("测试结束-----------------");
}
}
- @BeforeClass 基类执行前触发
- @AfterClass 基类执行后触发
- @Before 每个@Test方法调用前触发
- @After 每个@Test方法调用后触发

- @Ignore 忽略测试方法
- @Test 执行单元测试的方法
使用StopWatch可以统计单元测试类执行总时间以及每个@Test方法执行时间。
