如何使用Mockito模拟并使用Junit5断言抛出的异常和消息？

import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.mockito.Mockito;

import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.junit.jupiter.api.Assertions.assertThrows;

public class MyServiceTest {
    private MyService myService;
    private MyDependency myDependency;

    @BeforeEach
    public void setup() {
        myDependency = Mockito.mock(MyDependency.class);
        myService = new MyService(myDependency);
    }

    @Test
    public void testDoSomething() {
        // 模拟myDependency的方法调用，并指定返回结果
        Mockito.when(myDependency.doSomething()).thenReturn("Mocked result");

        // 断言调用myService的方法是否按预期返回结果
        assertEquals("Mocked result", myService.doSomething());

        // 模拟抛出异常
        Mockito.doThrow(new RuntimeException("Mocked exception")).when(myDependency).doSomething();

        // 断言调用myService的方法是否抛出了预期的异常
        RuntimeException exception = assertThrows(RuntimeException.class, () -> myService.doSomething());
        assertEquals("Mocked exception", exception.getMessage());
    }
}
