11. spring-test

Maven坐标：

<!-- spring-test -->
<dependency>
  <groupId>org.springframework</groupId>
  <artifactId>spring-test</artifactId>
  <version>5.2.7.RELEASE</version>
  <scope>test</scope>
</dependency>

还需要导入junit依赖：

<!--junit单元测试-->
<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.11</version>
  <scope>test</scope>
</dependency>

<dependency>
  <groupId>org.junit.jupiter</groupId>
  <artifactId>junit-jupiter-api</artifactId>
  <version>5.6.2</version>
  <scope>test</scope>
</dependency>

简单用法：

Spring + Junit4：

@RunWith(SpringRunner.class)
@ContextConfiguration(locations = {"classpath:ApplicationContext.xml"})
public class TestUserService{
  //自动装配
  @Autowired
  @Qualifier("userServiceImpl")
  UserService userService;

  @Test
  public void test(){

  }
}

@RunWith(SpringRunner.class)测试环境

@ContextConfiguration(locations = {"classpath:ApplicationContext.xml"})导入上下文配置

这是两个常用注解，测试类中可以实现自动装配

Spring + Junit5：

@ExtendWith(SpringExtension.class)
@ContextConfiguration(locations = {"classpath:ApplicationContext.xml"})
public class TestUserService{

  //自动装配
  @Autowired
  @Qualifier("userServiceImpl")
  UserService userService;

  public void test(){

  }
}

@ExtendWith(SpringExtension.class)替换了Junit4的RunWith

@ContextConfiguration(locations = {"classpath:ApplicationContext.xml"})导入上下文配置
