Laravel Feature Tests always return 404 - php

Question

I'm struggling to make my Feature Tests run with Laravel. I ran out of options. This is the error I get (with withoutExceptionHandling to show the URL):
• Tests\Feature\ClientTest > example
Symfony\Component\HttpKernel\Exception\NotFoundHttpException
GET http://localhost/sunny-camping/welcome
at vendor/laravel/framework/src/Illuminate/Foundation/Http/Kernel.php:416
412▕ * #return \Symfony\Component\HttpFoundation\Response
413▕ */
414▕ protected function renderException($request, Throwable $e)
415▕ {
➜ 416▕ return $this->app[ExceptionHandler::class]->render($request, $e);
417▕ }
418▕
419▕ /**
420▕ * Get the application's route middleware groups.
+1 vendor frames
2 tests/Feature/ClientTest.php:19
Illuminate\Foundation\Testing\TestCase::get()
Obviously if I click the URL everything works fine, but the test gives me 404... The page itself is default welcome page from Laravel. Now for the files:
ClientTest.php
<?php
namespace Tests\Feature;
use Illuminate\Foundation\Testing\RefreshDatabase;
use Illuminate\Foundation\Testing\WithFaker;
use Tests\TestCase;
class ClientTest extends TestCase
{
/**
* A basic feature test example.
*
* #return void
*/
public function test_example()
{
$this->withoutExceptionHandling();
$response = $this->get('/welcome');
$response->assertStatus(200);
}
}
web.php
<?php
use App\Http\Controllers\Admin\ClientController;
use App\Http\Controllers\AdminController;
use App\Http\Controllers\HomeController;
use Illuminate\Support\Facades\Route;
/*

*/
Route::get('/{year?}', [HomeController::class, 'home'])->where('year', '[0-9]+')->name('home');
Route::prefix('/admin')->group(function () {
Route::prefix('/clients')->group(function () {
Route::get('/add-client', [ClientController::class, 'addClient']);
Route::get('/edit/{id}', [ClientController::class, 'edit'])->name('admin.clients.edit');
Route::put('/add', [ClientController::class, 'add']);
Route::patch('/update/{id}', [ClientController::class, 'update']);
Route::delete('/delete/{id}', [ClientController::class, 'delete']);
Route::get('/paginated-json', [ClientController::class, 'paginatedJson']);
Route::get('/find-json/{id}', [ClientController::class, 'findJson']);
});
Route::get('/dashboard', [AdminController::class, 'dashboard'])->name('admin.dashboard');
Route::get('/clients', [AdminController::class, 'clients'])->name('admin.clients');
Route::get('/bills', [AdminController::class, 'bills']);
Route::redirect('/', 'admin/dashboard');
});
Route::get('/welcome', function () {
return view('welcome');
});
I'm running everything from Windows Subsystem Linux, using Apache and MariaDB.
So far I tried multiple things:
php artisan serve (no clue why but it helped some people, not me though)
Different URIs
Making .env.testing file with APP_URL set to the same as .env file
Adding APP_URL to phpunit.xml file <server name="APP_URL" value="http://localhost/sunny-camping"/>
Pasting full URLs as the URI
Copying URIs from php artisan routes:list
Using `route('myroutename')' instead of URI
All of this to no avail. I keep getting 404 and I have no clue how to fix this. I went through multiple queries and over 2 pages of Google and found no solution...
Any ideas are appreciated.

Turns out, tests act in a (to me) very weird way. They use a different APP_URL than everything else.
So to fix this, you either have to set you APP_URL to just http://localhost in your .env.testing file, or add <server name="APP_URL" value="http://localhost"/> to your phpunit.xml file, given similar file structure. (Unfortunately I don't understand this enough to be able to tell how this will behave if your project is in deeper folders or non-local server)
