Laravel php testing, called undefined function? - laravel

Question

I write a code using laravel 8 and i want to create CRUD Testing for all model so i can called it in every test case, for example I Have Operator Test that extends TestCase (crud testing master) ref : crud test, this is my Operator Test looks like,..
<?php
namespace Tests\Feature;
use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithFaker;
use Tests\TestCase;
class OperatorTest extends TestCase
{
use RefreshDatabase, WithFaker;
public function test_user_can_update_an_operator()
{
$this->setBaseRoute('master.operator');
$this->setBaseModel('App\Models\Operator');
$this->signIn();
$this->attributes = [
'username' => 'test update',
'level' => 1,
'category_id' => 1,
'password' => 'password'
];
$this->update($this->attributes);
}
}
and this is my TestCase.php looks like,...
<?php
namespace Tests;
use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\TestCase as BaseTestCase;
use App\Models\Operator;
use Illuminate\Foundation\Testing\WithFaker;
abstract class TestCase extends BaseTestCase
{
use CreatesApplication;
use RefreshDatabase;
protected $base_route = null;
protected $base_model = null;
protected function signIn($user = null)
{
$user = $user ?? Operator::factory()->create();
$this->actingAs($user);
return $this;
}
protected function setBaseRoute($route)
{
$this->base_route = $route;
}
protected function setBaseModel($model)
{
$this->base_model = $model;
}
protected function update($attributes = [], $model = '', $route = '')
{
$this->withoutExceptionHandling();
$route = $this->base_route ? "{$this->base_route}.update" : $route;
$model = $this->base_model ?? $model;
$model = create($model);
if (! auth()->user()) {
$this->expectException(\Illuminate\Auth\AuthenticationException::class);
}
$response = $this->patchJson(route($route, $model->id), $attributes);
tap($model->fresh(), function ($model) use ($attributes) {
collect($attributes)->each(function($value, $key) use ($model) {
$this->assertEquals($value, $model[$key]);
});
});
return $response;
}
}
after that when I tun php artisan test, i got an error like this :
anything worng in my codes ? i used laravel 8.

You need to initialize the model first and then call the model factory.
The create function is undefined at line 64.
Instead of
$model = create($model);
Use bellow code
$model = app()->make($model)
$model = $model::factory()->create();
More information on app()->make() and factory.
