PHPUnit错误：未定义的常量，而常量确实存在答案

【问题标题】：PHPUnit Error: Undefined constant while constant does existPHPUnit错误：未定义的常量，而常量确实存在

【问题描述】：

我正在使用 PHP Unit 9.5，我正在调用我的类：(new Resolvers())();

但这会导致以下错误：Error: Undefined constant 'Cryptoactive\User\USER_REPOSITORY'。该常量确实存在于引用类中。

解析器.php

use ...\Container;
use const ...\User\USER_REPOSITORY;

class Resolvers
{
    private UserRepository $users;

    public function __invoke(): array
    {
        $this->users = Container\get(USER_REPOSITORY);

        return [
            'Query' => [
                'user' => fn (?array $root, $args) => (new UserQuery($this->users, new FindOne($args['id'])))(),
                'users' => new UserQuery($this->users, new FindAll())
            ],
            'Mutation' => [
                'saveUser' => new UserSave($this->users)
            ],
            'Subscription' => [
                'events' => []
            ]
        ];
    }
}

【解决方案1】：

您不能“导入”或“使用”像 use const ...\User\USER_REPOSITORY; 这样的不是有效语法的常量...

你必须这样做：

use ...\User;

class Resolvers
{
    private UserRepository $users;

    public function __invoke(): array
    {
        $this->users = Container\get(User::USER_REPOSITORY);

        return [
            'Query' => [
                'user' => fn (?array $root, $args) => (new UserQuery($this->users, new FindOne($args['id'])))(),
                'users' => new UserQuery($this->users, new FindAll())
            ],
            'Mutation' => [
                'saveUser' => new UserSave($this->users)
            ],
            'Subscription' => [
                'events' => []
            ]
        ];
    }
}
