phpunit断言-assertIsIterable

发布时间：2021-10-03 21:05:13编辑：雪饮阅读（）

 assertIsIterable断言用于断言一个实际值是否是一个迭代类型。

IterableTest.php：
<?php
use PHPUnit\Framework\TestCase;

class IterableTest extends TestCase
{
    public function testFailure()
    {
        $this->assertIsIterable(null);
    }
    public function testTwo()
    {
        $this->assertIsIterable([]);
    }
}
运行结果如：
