phpunit断言assertClassHasStaticAttribute

发布时间：2021-10-01 13:30:08编辑：雪饮阅读（）

 Phpunit断言中的assertClassHasStaticAttribute方法主要用于断言一个类中是否拥有某个静态变量，若拥有这个静态变量则断言为真，否则断言为false。

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

final class ClassHasStaticAttributeTest extends TestCase
{
    static $a="b";
    public $b="c";
    public function testFailure(): void
    {
        $this->assertClassHasStaticAttribute('foo', stdClass::class);
    }
    public function testSuccess(): void
    {
        $this->assertClassHasStaticAttribute('a', ClassHasStaticAttributeTest::class);
    }
    public function testFailureP(): void
    {
        $this->assertClassHasStaticAttribute('b', ClassHasStaticAttributeTest::class);
    }
}

这里有3个断言，第一个stdclass中肯定不存在静态的foo属性
第二个断言当前类自身存在静态属性a，这个很明显是ok的
第三个断言当前类自身存在静态属性b，这个就错了，当前类存在属性b，但是并非静态。
