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) {
        if (b == 0) {
            throw new ArithmeticException("Division by zero");
        }
        return a / b;
    }
}

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

public class CalculatorTest {

    @Test
    public void testDivideByZero() {
        Calculator calculator = new Calculator();
        assertThrows(ArithmeticException.class, () -> calculator.divide(10, 0));
    }
}

import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.*;

public class UnexpectedExceptionTest {

    @Test
    public void testUnexpectedException() {
        Calculator calculator = new Calculator();
        Exception exception = assertThrows(Exception.class, () -> {
            // 这里故意调用一个会抛出意外异常的方法
            throw new RuntimeException("Unexpected exception");
        });

        assertEquals("Unexpected exception", exception.getMessage());
    }
}
