Laravel 5 Symfony\Component\HttpKernel\Exception\NotFoundHttpException: POST http://localhost/myproject/public/leads

I use Laravel 5.8 and have test method like this this

public function test_store()
{
   $attribute= ['lead_name'=>'test_name','lead_family'=>'test_family'];
   $this->post('/leads', $attribute);
   $this->assertDatabaseHas('leads',  $attribute);
}

and controller like this:

class LeadController extends Controller
{
   public function store(Request $request)
   {
       Lead::create($request->all());
   }
}

and route :

Route::resource('/leads', 'App\Http\Controller\LeadController');

When I run phpunit show me this error:

Symfony\Component\HttpKernel\Exception\NotFoundHttpException: POST http://localhost/myproject/public/leads
