[实操]hello-JUnit

1. 依赖

<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>

2. 建包

3. 编写测试类

public class UserServiceTest {

    private UserService userService;

    @Before
    public void before(){
        System.out.println("初始化数据库连接");
        ApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring-context.xml");
        userService = (UserService) applicationContext.getBean("userService");
    }

    @Test
    public void testSayHi(){
        userService.sayHi();
    }

    @After
    public void after(){
        System.out.println("关闭数据库连接");
    }
}
