-#### ONLY for Laravel 5.3
-
-Before start using the package on Laravel 5.3, we need some configuration to make testing works (since it still has BrowserKit Testing features, we will use existing Laravel BaseTest Class and PHPUnit 5.7).
-
-```bash
-$ vendor:publish --provider='Luthfi\CrudGenerator\ServiceProvider'
-```
-
-Then on `config/simple-crud.php` edit "base_test_path" and "base_test_class" value:
-
-```php
-// config/simple-crud.php
-
-    'base_test_path' => 'tests/TestCase.php',
-    'base_test_class' => 'TestCase',
-```
-
-Then add **loginAsUser** method on `tests/TestCase.php` file :
-
-```php
-<?php
-
-use App\User;
-
-abstract class TestCase extends Illuminate\Foundation\Testing\TestCase
-{
-    // ... method createApplication()
-
-    protected function loginAsUser()

-        $this->actingAs($user);

-Done, you may continue to [try the testing suite](#lets-try-the-generated-testing-suite). Please [let me know](https://github.com/nafiesl/SimpleCrudGenerator/issues/new) if this configuration had **any issue**.
