memory leak in controller testing for json response

[beornborn]

describe "GET anchor" do
  context 'timestamp is not a number' do
    it 'shows error' do
      get :anchor, {auth_token: 'qwerty', timestamp: 'string'}
      expect(response).to eq({success: false, anchor: nil, error: 'Timestamp should be a number'})
    end
  end
end

when I edit
expect(response).to eq({success: false, anchor: nil, error: 'Timestamp should be a number'})
to
expect(response.body).to eq({success: false, anchor: nil, error: 'Timestamp should be a number'}.to_json)
it works.

but rspec should show the fail, but not begin to eat memory

Yep, this is a bug in Rack. See rack/rack#419 and previous rspec issues #166 and rspec/rspec-rails#601
