redeclaring method when i try to mock it

Question

i have a class that is binded in service provider
this class uses my facade which extends the laravel's facade,but
when i try to mock the class it say's
Cannot redeclare Mockery_1_App_Classes_Dashboard_class::shouldReceive().

my test method:

    public function test_method()
    {
        class::shouldReceive('method')->once()->andReturns(true);

        $response = $this->another_class->method();

        dd($response);
    }

my facade :

<?php

namespace App\Facades\Dashboard;

use Illuminate\Support\Facades\Facade;

class class extends Facade
{
    protected static function getFacadeAccessor()
    {
        return 'class';
    }
}

AppServiceProvider :

<?php

namespace App\Providers;

use Illuminate\Database\Eloquent\Relations\Relation;
use Illuminate\Support\Facades\Schema;
use Illuminate\Support\ServiceProvider;

use App\Classes\Dashboard\class;

class AppServiceProvider extends ServiceProvider
{
    public function register()
    {
        $this->app->bind('class', function($app) {
            return new class;
        });
    }

    public function boot()
    {
        Schema::defaultStringLength(191);
    }
}

i searched the web, unfortunately haven't find anything.

Answer 1

finally found the problem.
i was accidentally extending laravel's facade in my class inheritance.
