如何在springBoot中编写Junit测试用例？

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-test</artifactId>
    <scope>test</scope>
</dependency>

@RunWith(SpringRunner.class)
@SpringBootTest
public class MyServiceTest {
    // 测试代码
}

@RunWith(SpringRunner.class)
@SpringBootTest
public class MyServiceTest {
    @Autowired
    private MyService myService;

    // 测试代码
}

@RunWith(SpringRunner.class)
@SpringBootTest
public class MyServiceTest {
    @Autowired
    private MyService myService;

    @Test
    public void testSomeMethod() {
        // 测试逻辑
    }
}

@RunWith(SpringRunner.class)
@SpringBootTest
public class MyServiceTest {
    @Autowired
    private MyService myService;

    @Test
    public void testSomeMethod() {
        int result = myService.someMethod(2, 3);
        Assert.assertEquals(5, result);
    }
}
