phpunit断言-assertEmpty

发布时间：2021-10-02 11:45:51编辑：雪饮阅读（）

 assertEmpty断言就很简单，断言一个如变量是否为empty。

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

final class EmptyTest extends TestCase
{
    public function testFailure(): void
    {
        $this->assertEmpty(['foo']);
    }
    public function testSuccess(): void
    {
        $this->assertEmpty([]);
    }
}
运行效果：
