我尝试为我的 User
之间的关系创建单元测试和 Shop
模型,但是当我运行 vendor\\bin\\phpunit
抛出此错误,我对此一无所知,因为我是单元测试的新手。我试图在我的 Controller 上运行我的代码,看看这种关系是否真的有效,幸运的是它按预期工作,但在 phpunit 中运行时却没有。这个 phpunit 不能与模型一起工作,我做错了什么?
Fatal error:
Uncaught Error: Call to a member function connection() on null in E:\projects\try\vendor\laravel\framework\src\Illuminate\Database\Eloquent\Model.php:1013
Stack trace:
E:\projects\try\vendor\laravel\framework\src\Illuminate\Database\Eloquent\Model.php(979): Illuminate\Database\Eloquent\Model::resolveConnection(NULL)
这是我的 UserTest.php
<?php
namespace Tests\Unit;
use Tests\TestCase;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;
use App\User;
use App\Shop;
class UserTest extends TestCase
{
protected $user, $shop;
function __construct()
{
$this->setUp();
}
function setUp()
{
$user = new User([
'id' => 1,
'first_name' => 'John',
'last_name' => 'Doe',
'email' => 'JohnDoe@example.com',
'password' => 'secret',
'facebook_id' => null,
'type' => 'customer',
'confirmation_code' => null,
'newsletter_subscription' => 0,
'last_online' => null,
'telephone' => null,
'mobile' => null,
'social_security_id' => null,
'address_1' => null,
'address_2' => null,
'city' => null,
'zip_code' => null,
'signed_agreement' => 0,
'is_email_confirmed' => 0
]);
$user = User::find(1);
$shop = new Shop([
'id' => 1,
'user_id' => $user->id,
'name' => 'PureFoods Hotdog2',
'description' => 'Something that describes this shop',
'url' => null,
'currency' => 'USD'
]);
$user->shops()->save($shop);
$shop = new Shop([
'id' => 2,
'user_id' => $user->id,
'name' => 'PureFoods Hotdog',
'description' => 'Something that describes this shop',
'url' => null,
'currency' => 'USD'
]);
$user->shops()->save($shop);
$this->user = $user;
}
/** @test */
public function a_user_has_an_id(){
$user = User::find(1);
$this->assertEquals(1, $user->id);
}
/** @test */
public function a_user_has_a_first_name()
{
$this->assertEquals("John", $this->user->first_name);
}
/** @test */
public function a_user_can_own_multiple_shops()
{
$shops = User::find(1)->shops()->get();
var_dump($this->shops);
$this->assertCount(2, $shops);
}
}
看来,这个错误是由这行代码引起的:
$user->shops()->save($shop);
- 此代码在我的示例路由或 Controller 中运行时实际上有效,但抛出 errors
在 phpunit
中运行时
User.php
<?php
namespace App;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
use Notifiable;
protected $guarded = [ 'id' ];
protected $table = "users";
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'password', 'remember_token',
];
/**
* returns the Shops that this user owned
*/
public function shops()
{
return $this->hasMany('App\Shop');
}
}
Shop.php
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Shop extends Model
{
protected $guarded = [ 'id' ];
protected $table = "shops";
/**
* returns the Owner of this Shop
*/
public function owner()
{
return $this->belongsTo('App\User');
}
}
任何帮助将不胜感激。谢谢!
最佳答案
首先,setUp()
在每次测试之前都会被调用,因此您不应该在构造函数中调用它
其次,您应该在 setUp()
中调用 parent::setUp()
初始化应用程序实例。
