问题描述
试图在这里测试模型，但是每次我尝试使用assertDatabaseHas方法时，都会给我类型错误. Laravel 5.4和PHPUnit 6.
Trying to test a model here, but every time that I try to use the assertDatabaseHas method it gives me the type error. Laravel 5.4 and PHPUnit 6.

ERRORS!
Tests: 3, Assertions: 2, Errors: 1.
测试类中的代码:
$this->assertDatabaseHas('domains', [
'domain' => $domain,
'domain_type' => 'full_domain',
]);
我使用laravel文档作为参考，并且语法似乎是正确的(至少对我而言). https://laravel.com/docs/5.4/database-testing#introduction
I using the laravel docs as reference and the syntax seems to be correct (at least for me). https://laravel.com/docs/5.4/database-testing#introduction
在此先感谢您的帮助.
推荐答案
问题似乎是Laravel 5.4不支持版本6引入的PHPUnit的命名空间.
The problem seems to be that Laravel 5.4 does not support the namespace for PHPUnit introduced with version 6.
如果比较分支，很容易看到:
If you compare the branches it is easy to see:
vs.
我认为最好的解决方案是使用PHPUnit 5.x运行测试，或者可能更新laravel/framework以使用master.由于主服务器可能包含重大更改，因此第一种似乎是目前较为安全的方法.
I think the best solution is to either run the tests with PHPUnit 5.x or possibly update laravel/framework to use master. Since the master might contain breaking changes the first seems to be the safer approach for now.
