Middleware not reached when running the test

It may be how I am running the test but for some reason my Middleware isn't reaching when I run the test.

beforeEach I have a user that belongs to company_id 1 as it refreshes the database.

So I created a middleware empty one, just dd()

class EnsureCustomerBelongToCompany
{
    /**
     * Handle an incoming request.
     *
     * @param Closure(Request): (Response) $next
     */
    public function handle(Request $request, Closure $next): Response
    {
      
        dd($customer);

        return $next($request);
    }
}

On my routes:

 Route::middleware(EnsureCustomerBelongToCompany::class)->group(function () {
   	          .. rest of routes
	          Route::put('/{id}', [CustomerController::class, 'update'])->name('customers.update');
        });

The test:

it("should redirect if the user tries to update a customer that belongs to another company", function () {

    // create a new company other than the beForeEach company, this is probably the company id 2
    Company::factory()->create();
    $customerOfCompany2 = Customer::factory()->create(['company_id' => 2]);

// This user has company_1 middleware is supposed to check if the $customerOfCompany2->id belogns to logged in user ( before controller ) 
    actingAs($this->user)->put(route('customers.update', $customerOfCompany2->id), $customerOfCompany2->toArray())
        ->assertRedirect(route('customers.index'));
});

It is passing on test due to Controller logic, but I am looking to make some further validation even before controller / formRequest, however, whenever I run the test the dd() is never reached.

Any idea on what I am failing?
