如何在mockito+J单元测试中捕获或模拟意外的异常？

public class Calculator {
    public int divide(int a, int b) {
        return a / b;
    }
}

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

import static org.junit.Assert.assertEquals;

public class CalculatorTest {
    
    @Test(expected = ArithmeticException.class)
    public void testDivideByZero() {
        // 创建Calculator对象的mock实例
        Calculator calculator = Mockito.mock(Calculator.class);
        
        // 当调用divide方法时，抛出ArithmeticException异常
        Mockito.doThrow(new ArithmeticException("除数不能为零")).when(calculator).divide(Mockito.anyInt(), Mockito.eq(0));
        
        // 调用divide方法，会抛出ArithmeticException异常
        calculator.divide(10, 0);
    }
    
    @Test
    public void testDivide() {
        Calculator calculator = new Calculator();
        
        // 正常调用divide方法，不会抛出异常
        int result = calculator.divide(10, 2);
        
        // 验证结果是否符合预期
        assertEquals(5, result);
    }
}
