Mocking not initialized in around(:each) blocks.

[tylerhunt]

The mocking framework appears to not be initialized properly before the example is run in an around block.

RSpec.configure do |config|
  config.mock_with :rspec
end

describe 'around mocking' do
  let!(:now) { Time.now }

  around(:each) do |example|
    Time.stub(:now).and_return(now)
    example.run
  end

  specify { Time.now.should == now }
end

This results in the following failure:

Run filtered 
F

Failures:

  1) around mocking 
     Failure/Error: Time.stub(:now).and_return(now)
     NoMethodError:
       undefined method `stub' for Time:Class
     # ./bug.rb:9

Changing the around to a before works as expected, and after example.run is called, the mocking methods are available inside the around block. It appears the source of the the bug is that RSpec::Core::Example#run_before_each is where the mocking framework is set up (@example_group_instance.setup_mocks_for_rspec), but around begins executing before this code is called.

Mocking is unsupported in around hooks. I'll leave that open until this fact gets documented.

The mocking framework is verified/reset after each example, so doing this in a before is just fine.
