Run php artisan help <command> for detailed usage.
Creating Custom Commands
How to create your own Artisan commands.
// Create a new command
php artisan make:command MyCustomCommand
// MyCustomCommand.php
protected $signature = 'custom:command';
protected $description = 'Description of the custom command';
public function handle()
{
$this->info('Custom command executed!');
}Use descriptive names for commands.
Leverage the handle method for command logic.
Testing in Laravel
3 topics
Unit Testing
Writing unit tests for your application.
// ExampleTest.php
public function test_example()
{
$response = $this->get('/');
$response->assertStatus(200);
}Use PHPUnit for unit testing.
Run tests using php artisan test.
Feature Testing
Testing application features.
// FeatureTest.php
public function test_home_page()
{
$response = $this->get('/home');
$response->assertSee('Welcome');
}Use feature tests for end-to-end testing.
Mock dependencies for isolated tests.
Database Testing
Testing database interactions.
// DatabaseTest.php
public function test_database()
{
User::factory()->create(['name' => 'John Doe']);
$this->assertDatabaseHas('users', ['name' => 'John Doe']);
}Use factories for test data.
