如何使用mockito为这个控制器类编写单元测试用例

<dependency>
    <groupId>org.mockito</groupId>
    <artifactId>mockito-core</artifactId>
    <version>3.12.4</version>
    <scope>test</scope>
</dependency>

public class MyController {
    private MyService myService;

    public MyController(MyService myService) {
        this.myService = myService;
    }

    public String doSomething() {
        // 调用MyService的方法
        return myService.doSomething();
    }
}

import org.junit.jupiter.api.Test;
import static org.mockito.Mockito.*;

public class MyControllerTest {
    @Test
    public void testDoSomething() {
        // 创建Mock对象
        MyService myServiceMock = mock(MyService.class);

        // 设置Mock对象的行为
        when(myServiceMock.doSomething()).thenReturn("Mocked result");

        // 创建被测试的控制器对象，并传入Mock对象
        MyController myController = new MyController(myServiceMock);

        // 调用被测试的方法
        String result = myController.doSomething();

        // 验证结果
        assertEquals("Mocked result", result);

        // 验证Mock对象的方法是否被调用
        verify(myServiceMock).doSomething();
    }
}
