Unable to successfully mock Config::shouldReceive('get')->with('my_testing_param_here'); because the application boots and it will start to ask you for every single required app configuration parameter

My test started to look like this before I called it quits:

        Config::shouldReceive('offsetGet')
            ->with('database.default')
            ->andReturn('DEFAULT_DATABASE')
        ;

        Config::shouldReceive('offsetGet')
            ->with('database.connections')
            ->andReturn(['DEFAULT_DATABASE' => [
            'driver'    => 'mysql',
            'host'      => 'HOST'
            'database'  => 'DATABASE',
            'charset'   => 'utf8',
            'collation' => 'utf8_unicode_ci',
            'prefix'    => '',
            'strict'    => false,
        ]])
        ;

        Config::shouldReceive('offsetGet')->with('database.fetch');
        
        // never ending configuration parameters until the application is fully booted

This is totally untestable if you're trying to just get a Config value. Is there a shortcut method out there?
