phpunit断言-assertInstanceOf

发布时间：2021-10-03 12:19:14编辑：雪饮阅读（）

 assertInstanceOf断言用来断言一个实际实例的直属类是一个预期类。

InstanceOfTest.php：
<?php declare(strict_types=1);
use PHPUnit\Framework\TestCase;

final class InstanceOfTest extends TestCase
{
    public function testFailure(): void
    {
        $this->assertInstanceOf(RuntimeException::class, new Exception);
    }
    public function testSuccess(): void
    {
        $this->assertInstanceOf(RuntimeException::class, new RuntimeException);
    }
}
运行结果如：
