Laravel Dusk not picking up APP_URL in .env.dusk.local file

Laravel dusk does not seem to use the APP_URL set in .env.dusk.local file.

This is my .env.dusk.local file:

APP_URL=http://local.project/
BASE_URL=http://local.project/
APP_ENV=testing
DB_CONNECTION=dusk

This is my login test:

<?php

 namespace Tests\Browser;

 use Tests\DuskTestCase;

     class LoginTest extends DuskTestCase
     {

     /**
     * test_I_can_login_successfully
     *
     * @return void
     */
      public function test_I_can_login_successfully()
      {
             $this->browse(function ($browser) {
             $browser->visit('login')
                    ->keys('#email', 'test@test.co.uk')
                    ->keys('#password', 'test')
                    ->click('.btn-primary')
                    ->assertPathIs('dashboard')
                    ->assertSee('Marco');
                });
        }

   }

But when I run the test instead of going to http://local.project/login goes to http://localhost/public/local

Why is that?
