更新后 Laravel / PHP 单元测试失败

Question

在将 Laravel 从 5.4 更新到 5.8 和 PHPUnit 8 之后，一些测试开始失败。它似乎与 Authenticatable 有关，但我不确定如何修复它。在阅读了其他一些帖子之后，我似乎需要更改用户模型。运行我的一项测试时，我看到以下错误

1) DataViewControllerTest::testImportWithRecords
TypeError: Argument 1 passed to Laravel\BrowserKitTesting\TestCase::actingAs() must implement interface Illuminate\Contracts\Auth\Authenticatable, null given, called in /var/www/tests/Feature/Controllers/DataViewControllerTest.php on line 41

用户模型

<?php

namespace App\Models;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Auth;

class User extends Authenticatable
{
    use Notifiable;
    public static $snakeAttributes = false;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

}

由于整个 DataViewControllerTest.php 很长，我附上了相关部分。

    public function setUp() {
           parent::setUp();
           Artisan::call('migrate');
           Artisan::call('db:seed');
           Session::setDefaultDriver('array');
           $this->manager = app('session');

           // find admin and test user accounts
           $this->admin = User::where('name', '=', 'admin')->first();
           $this->user = User::where('name', '=', 'test')->first();
    }

失败似乎从这里开始我正在调用这个动态创建新表的例程。 Admin 在上面的设置中定义。

    public function createTestTable($tblname, $path, $file) {
            // create a test collection
            $this->collection = (new TestHelper)->createCollection('collection1');

            $this->actingAs($this->admin)
                 ->visit('table/create')
                 ->type($tblname, 'imprtTblNme')
                 ->type('1', 'colID')
                 ->attach($path . $file, 'fltFile')
                 ->press('Import')
                 ->assertResponseStatus(200)

任何建议将不胜感激。

Answer 1

以下代码可能没有返回任何内容：

// find admin and test user accounts
$this->admin = User::where('name', '=', 'admin')->first();

这可能与您的播种机或迁移有关。

我建议以下步骤： 1. 检查你的播种器，看看是否添加了管理员用户。

考虑添加此代码：

$this->admin = User::where('name', '=', 'admin')->first();
if($this->admin == null){
  $this->fail('No admin user present');
}
