如何模拟java.util.Random类的依赖关系？

import org.junit.Test;
import org.mockito.Mock;
import org.mockito.MockitoAnnotations;

import java.util.Random;

import static org.junit.Assert.assertEquals;
import static org.mockito.Mockito.when;

public class RandomDependencyTest {

    @Mock
    private Random random;

    @Test
    public void testRandomDependency() {
        // 初始化Mock对象
        MockitoAnnotations.initMocks(this);

        // 设置Mock对象的行为
        when(random.nextInt()).thenReturn(5);

        // 使用Mock对象进行测试
        MyClass myClass = new MyClass(random);
        int result = myClass.generateRandomNumber();

        // 验证结果
        assertEquals(5, result);
    }

    // 示例类，依赖于java.util.Random类
    private static class MyClass {
        private Random random;

        public MyClass(Random random) {
            this.random = random;
        }

        public int generateRandomNumber() {
            return random.nextInt();
        }
    }
}
