Argument 1 passed to Illuminate\Foundation\Testing\TestCase::actingAs() - php

Question

I wanna try to make test, member who logged in can create a job, this is my test code.
/** #test */
public function member_can_create_a_job(){
$member = factory('App\Models\M_member')->create();
$this->actingAs($member);
$job = factory('App\Models\M_lowker')->make();
$this->post('/lowker/tambah-lowker', $job->toArray())->assertRedirect('/lowker/tambah-lowker');
}
This is my App\Models\M_member
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
class M_member extends Model{
protected $table = "member";
public $timestamps = false;
protected $fillable = ["nama", "email", "password", "alamat", "tgl_lahir", "remember_token"];
public function jobs()
{
return $this->hasMany('App\Models\M_lowker');
}
public function comments()
{
return $this->hasMany('App\Models\M_komentar');
}
}
When I run, I get error in cmd like
this.

Answer 1

This error tells you that the model which you are using is not extending the Illuminate\Contracts\Auth\Authenticatable contract, which is necessary to use the actingAs method. If you have laravel's auth you can check the user model as an example of this . Which is something like:
<?php
namespace App;
use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
So, try extending your model to have this functionality.
or you can implement the Authenticatable contract on your model like this
class User extends Model implements
AuthenticatableContract,
AuthorizableContract,
CanResetPasswordContract
{
use Authenticatable, Authorizable, CanResetPassword;
}

Answer 2

You can add first() when you create user
$user = factory('App\User')->create()->first();

Answer 3

This problem solved with modify my M_member model like this.
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Contracts\Auth\Authenticatable;
use Illuminate\Auth\Authenticatable as AuthenticableTrait;
class M_member extends Model implements Authenticatable{
use AuthenticableTrait;
