Mocking Cache Facade throws InvalidArgumentException

[tillkruss]

The code from the 5.1 docs to mock the Cache facade doesn't work: http://laravel.com/docs/5.1/testing#mocking-facades

Cache::shouldReceive('get')
   ->once()
   ->with('key')
   ->andReturn('value');

Error:

InvalidArgumentException: get() cannot be mocked as it a protected method and mocking protected methods is not allowed for this mock

Should this be fixed, or removed from the docs?

Does this work?

Cache::shouldReceive('driver->get')
   ->once()
   ->with('key')
   ->andReturn('value');

Throws:

BadMethodCallException: Method Mockery_0_Illuminate_Cache_CacheManager::tags() does not exist on this mock object

If I alter the code to:

Cache::shouldReceive('driver->get')
   ->once()
   ->tags('tag')
   ->with('key')
   ->andReturn('value');

It throws:

ErrorException: call_user_func_array() expects parameter 1 to be a valid callback, class 'Mockery\Expectation' does not have a method 'tags'

@GrahamCampbell So is this a bug, or should it be removed from the docs?
