迭代器对象

定义一个迭代器

<?php
namespace Test\Iterator;

class RmbIterAtor implements \IterAtor
{
    private $arr = [
        'first' => [1, 2, 3],
        'second' => [1, 3, 4],
        'third' => [1, 1, 0],
    ];

    public function current()
    {
        return current($this->arr);
    }

    public function key()
    {
        return key($this->arr);
    }

    public function next()
    {
        return next($this->arr);
    }

    public function rewind()
    {
        return reset($this->arr);
    }

    public function valid()
    {
        return current($this->arr);
    }
}

测试

<?php
require_once dirname(dirname(__FILE__)) . '\vendor\autoload.php';

use PHPUnit\Framework\TestCase;
use Test\iterator\RmbIterator;

class MyClassTest extends TestCase
{

    public function one()
    {
        return new RmbIterator;
    }

    /**
     * @test
     * @dataProvider one
     */
    public function two($arr_value_1, $arr_value_2, $arr_value_3)
    {

        $expectd_value = $arr_value_3;
        $actual_value = $arr_value_1 + $arr_value_2;
        $this->assertEquals($expectd_value, $actual_value, '当不相等,报这条错误信息');
    }

}
