如何在抽象类中执行@mock (而不是注入Mock)

public abstract class AbstractService {
    public abstract String fetchData();

    public void processData(String data) {
        // 处理数据的逻辑
        System.out.println("Processing: " + data);
    }
}

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

public class AbstractServiceTest {

    @Test
    public void testAbstractService() {
        // 创建AbstractService的Mock对象
        AbstractService mockService = Mockito.mock(AbstractService.class);

        // 定义Mock对象的行为
        Mockito.when(mockService.fetchData()).thenReturn("Mocked Data");

        // 调用方法并验证行为
        mockService.processData(mockService.fetchData());
    }
}
