        Capture<Integer> capArg = new Capture<Integer>();
        Capture<Object> capArray = new Capture<Object>();//Capture没有对应数组的,所以只能用Object存放数组,之后在强制性转换
        
        //这里是重点,需要调用capture方法捕获实际传入的参数
        //注意这里第一个参数必须用captureInt方法,不能用capture方法,否则因为传入参数类型不匹配而报错
        mockService.handle(captureInt(capArg), (int[])capture(capArray));
        
//        下面的写法也争取
//        int a1 = captureInt(capArg);
//        int[] a2 = (int[])capture(capArray);
//        mockService.handle(a1, a2);

        //这里我们将捕获的参数进行校验
        assertEquals(arg, actual1);
