我在运行测试时给出了这个错误:
未定义的变量$ faker.
这是WithFaker文件.
https://github.com/laravel/framework/blob/5.5/src/Illuminate/Foundation/Testing/WithFaker.php
<?php
namespace Tests\Unit;
use App\User;
use Tests\TestCase;
use Illuminate\Foundation\Testing\WithFaker;
use Illuminate\Foundation\Testing\RefreshDatabase;
class LoginTest extends TestCase
{
use WithFaker;
/**
* A basic test example.

*/
/** @test */
public function test_example()
{
$user = User::create([
'username' => $faker->firstName(),
]);
}
}
