Debugging Laravel Routes in Testing

Laravel’s routing system is one of its core strengths, providing an elegant way to define and handle application routes. While php artisan route:list is a great tool for listing routes, it’s not always convenient when debugging in code or during automated testing.

To address this, let’s build a utility function, routes, that retrieves all registered routes in a structured format. This function is especially useful for testing or debugging complex route setups.

Why Use the routes Function?

When working on tests or debugging route configurations, you might need to:

• Verify that specific routes exist.
• Check route names, URIs, or methods programmatically.
• Debug routes without relying on Artisan commands or running them outside the test environment.

The routes function provides a simple, reusable way to access and inspect routes in your application.

The routes Function

Here’s the implementation:

use Illuminate\Support\Facades\Route;

if (!function_exists('routes')) {
    /**
     * Retrieve all registered routes for debugging in a structured format.
     *
     * @param bool $dump Whether to dump the routes to the console.
     * @return \Illuminate\Support\Collection A collection of routes with details.
     */
    function routes(bool $dump = false)
    {
        $routes = collect(Route::getRoutes())->map(function ($route) {
            return [
                'uri' => $route->uri(),
                'name' => $route->getName(),
                'action' => $route->getActionName(),
                'methods' => $route->methods(),
            ];
        });

        if ($dump) {
            dump($routes); // Dumps routes to the console
        }

        return $routes;
    }
}

How to Use the routes Function

1. Debugging Routes in a Test:

   Use the function in a test to inspect all registered routes:
   

   it('retrieves all routes for debugging', function () {
       $all_routes = routes(true); // Dumps routes to the console
   
       $route_names = $all_routes->pluck('name')->all();
       expect($route_names)->toContain('home');
       expect($route_names)->toContain('dashboard');
   });
   

2. Customising Route Output:

   Filter or transform the routes as needed:
   

   it('retrieves only POST routes', function () {
       $post_routes = routes()
           ->filter(fn($route) => in_array('POST', $route['methods']));
   
       expect($post_routes->count())->toBeGreaterThan(0);
   });
   

3. Inspecting Routes in Development:

   Create a debugging route in your application to view all routes in JSON format:
   

   Route::get('/debug-routes', function () {
       return routes(); // Returns all routes as a JSON response
   });

Example Output

Calling routes(true) will display something like this:

[
    {
        "uri": "home",
        "name": "home",
        "action": "App\Http\Controllers\HomeController@index",
        "methods": ["GET", "HEAD"]
    },
    {
        "uri": "dashboard",
        "name": "dashboard",
        "action": "App\Http\Controllers\DashboardController@index",
        "methods": ["GET", "HEAD"]
    },
    ...
]

This structured output makes it easier to inspect and debug your routes.

Benefits of routes

• Convenient Debugging: Quickly view and debug routes without leaving the code.
• Improved Test Coverage: Validate your routes programmatically during testing.
• Reusable Utility: Easily integrate into any Laravel project for route inspection.
