Alternative facade mocking method

TestCase.php

  //this would go in the base TestCase class
  public function mockFacade($facadeName)
	{
		$facadeClass = get_class(call_user_func([$facadeName, 'getFacadeRoot']));
		$mock = m::mock($facadeClass);
		call_user_func([$facadeName, 'swap'], $mock);
		return $mock;
	}
  
  //it would be invoked like this:
  $this->mockFacade('Session')->shouldReceive('getToken')->once()->andReturn('token');
