Configurando un package para hacer tests.
Me he visto por primera vez ante la situación de tener que testear un package para Laravel que además estaba basado en Livewire. No ha sido fácil, y me ha llevado algo de tiempo tenerlo todo preparado, sobre todo porque no hay mucha información al respecto.
Lo primero ha sido crear el archivo TestCase.php en la carpeta ./tests. Dejo el archivo completo (que es del package Belich Tables):
<?php
namespace Daguilarm\BelichTables\Tests;
use Daguilarm\BelichTables\BelichTablesServiceProvider;
use Daguilarm\BelichTables\Tests\TestSeed;
use Illuminate\Support\Facades\Artisan;
use Illuminate\Support\Facades\File;
use Livewire\LivewireServiceProvider;
use Orchestra\Testbench\TestCase as BaseTestCase;
class TestCase extends BaseTestCase
{
use TestSeed;
/**
* Setup the test environment.
*/
public function setUp(): void
{
parent::setUp();
// Seed the database
$this->seedUsers();
$this->seedProfiles();
}
/**
* Load the service providers
*/
public function getPackageProviders($app)
{
return [
BelichTablesServiceProvider::class,
LivewireServiceProvider::class,
];
}
/**
* Setup the testing environment
*/
public function getEnvironmentSetUp($app)
{
// Setup the application
$app['config']->set('view.paths', [
__DIR__.'/views',
resource_path('views'),
]);
$app['config']->set('auth.providers.users.model', User::class);
$app['config']->set('app.key', 'base64:Hupx3yAySikrM2/edkZQNQHslgDWYfiBfCuSThJ5SK8=');
$app['config']->set('database.default', 'testbench');
$app['config']->set('database.connections.testbench', [
'driver' => 'sqlite',
'database' => ':memory:',
'prefix' => '',
]);
// Populate the DB
include_once __DIR__.'/../database/migrations/create_test_tables.php.stub';
(new \CreateTestTables())->up();
}
/**
* Swap HTTP Kernel for application bootstrap
*/
public function resolveApplicationHttpKernel($app)
{
$app->singleton('Illuminate\Contracts\Http\Kernel', 'Daguilarm\BelichTables\Tests\HttpKernel');
}
}
Antes de empezar tengo que aclarar que he tenido dos fuentes principales de información hasta llegar aquí:
- https://github.com/spatie/laravel-permission/blob/master/tests/TestCase.php
- https://github.com/livewire/livewire/blob/master/tests/Unit/TestCase.php
La clave para conseguir que funcionara, ha estado aqui:
/**
* Load the service providers
*/
protected function getPackageProviders($app)
{
return [
BelichTablesServiceProvider::class,
LivewireServiceProvider::class,
];
}
El problema era que cada vez que hacía un test, me daba el mismo error:
Illuminate\Contracts\Container\BindingResolutionException: Target class [livewire] does not exist.
La solución la encontré aqui:
Al principio sólo incluía el Service Provider de BelichTablesServiceProvider::class hasta que he decubierto que había que incluir también el de LivewireServiceProvider::class. Esto me ha llevado casi una hora delante del ordenador...
Sin olvidar el Trait TestSeed::class, que solo sirve para rellenar la base de datos:
<?php
namespace Daguilarm\BelichTables\Tests;
use Daguilarm\BelichTables\Tests\Models\Profile;
use Daguilarm\BelichTables\Tests\Models\User;
trait TestSeed
{
protected function seedUsers()
{
return User::insert([
[
'id' => 1,
'name' => 'Damián Aguilar',
'email' => 'damian.aguilar@email.com',
'active' => 1,
'date' => '2021-04-22 00:00:01'
],
[/* ... */],
]);
}
protected function seedProfiles()
{
return Profile::insert([
[
'id' => 1,
'user_id' => 1,
'profile_telephone' => '000000001'
],
[/* ... */],
]);
}
}
Otro aspecto importante si quieres utilizar los test que tiene Livewire disponibles, es tener en cuenta que hay que añadir todo el middleware, tal y como indicamos en el método resolveApplicationHttpKernel($app):
/**
* Swap HTTP Kernel for application bootstrap
*/
protected function resolveApplicationHttpKernel($app)
{
$app->singleton('Illuminate\Contracts\Http\Kernel', 'Daguilarm\BelichTables\Tests\HttpKernel');
}
Recuerdo que en nuestro TestCase hemos incluido este archivo, asi que tenemos que crearlo en la ruta que hemos especificado en el singleton. El archivo lo podemos encontrar en:
Y en caso que cambie de ubicación, lo copio aquí:
<?php
namespace Daguilarm\BelichTables\Tests;
use Illuminate\Foundation\Http\Kernel;
class HttpKernel extends Kernel
{
/**
* The application's global HTTP middleware stack.
*
* These middleware are run during every request to your application.
*
* @var array
*/
protected $middleware = [
\Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
\Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,
\Illuminate\Foundation\Http\Middleware\TrimStrings::class,
\Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
];
/**
* The application's route middleware groups.
*
* @var array
*/
protected $middlewareGroups = [
'web' => [
\Illuminate\Cookie\Middleware\EncryptCookies::class,
\Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse::class,
\Illuminate\Session\Middleware\StartSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,
\Illuminate\Foundation\Http\Middleware\VerifyCsrfToken::class,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
],
'api' => [
'throttle:60,1',
'bindings',
],
];
/**
* The application's route middleware.
*
* These middleware may be assigned to groups or used individually.
*
* @var array
*/
protected $routeMiddleware = [
'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,
'can' => \Illuminate\Auth\Middleware\Authorize::class,
'guest' => \Orchestra\Testbench\Http\Middleware\RedirectIfAuthenticated::class,
'signed' => \Illuminate\Routing\Middleware\ValidateSignature::class,
'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
'verified' => \Illuminate\Auth\Middleware\EnsureEmailIsVerified::class,
];
/**
* The priority-sorted list of middleware.
*
* This forces non-global middleware to always be in the given order.
*
* @var array
*/
protected $middlewarePriority = [
\Illuminate\Session\Middleware\StartSession::class,
\Illuminate\View\Middleware\ShareErrorsFromSession::class,
\Illuminate\Auth\Middleware\Authenticate::class,
\Illuminate\Session\Middleware\AuthenticateSession::class,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
\Illuminate\Auth\Middleware\Authorize::class,
];
}
Como recordatorio... no olvides cambiar los namespaces y adaptarlos a tu proyecto.
