The Laravel team released version 12.38.0, adding a WithCachedRoutes test trait, a WithCachedConfig test trait, a model prompt for the model:show command, and more.

WithCachedRoutes Testing Trait

Luke Kuzmish contributed the WithCachedRoutes trait, which builds routes once and stores them in memory. Routes are only built once for all tests in your test suite:

use App\Http\Controllers\UserController;
use Illuminate\Foundation\Testing\WithCachedRoutes;
use Tests\TestCase;
 
// Pest
pest()->use(WithCachedRoutes::class);
 
test('basic example', function () {
    $this->get(action([UserController::class, 'index']));
 
    // ...
});
 
// PHPUnit
class BasicTest extends TestCase
{
    use WithCachedRoutes;
 
    /**
     * A basic functional test example.
     */
    public function test_basic_example(): void
    {
        $response = $this->get(action([UserController::class, 'index']));
 
        // ...
    }
}

See Pull Request #57623 for more info.

WithCachedConfig Testing Trait

Luke Kuzmish contributed a WithCachedConfig trait, which builds the configuration in your app once and reuses it for all tests:

use Illuminate\Foundation\Testing\WithCachedConfig;
use Tests\TestCase;
 
// Pest
pest()->use(WithCachedConfig::class);
 
test('modifies config', function () {
    config(['services.postmark.key' => 'xyz']);
    expect(config('services.postmark.key'))->toBe('xyz');
});
 
test('uses default config', function () {
    expect(config('services.postmark.key'))->not->toBe('xyz');
});
 
// PHPUnit
class ConfigTest extends TestCase
{
    use WithCachedConfig;
 
    /**
     * A test that modifies the config.
     */
    public function test_modifies_config(): void
    {
        $this->assertEquals('xyz', config('services.postmark.key'));
    }
 
    /**
     * A test that makes no modification to the config.
     */
    public function test_uses_default_config(): void
    {
        $this->assertNotEquals('xyz', config('services.postmark.key'));
    }
}

See Pull Request #57663 for more info.

The model:show Command Now Prompts for Input

Razin Shaikh contributed an update to the model:show command to prompt for input when you run the command without arguments. Here's a before-and-after example:
