:none

The :none record mode allows previously recorded responses
to be replayed, but raises an error for any new requests.

This is useful when your code makes potentially dangerous
HTTP requests. The :none record mode guarantees that no
new HTTP requests will be made.

Background

Given

a file named "vcr_config.rb" with:

require 'vcr'

VCR.config do |c|
  c.stub_with                :fakeweb
  c.cassette_library_dir     = 'cassettes'
end

And

a previously recorded cassette file "cassettes/example.yml" with:

--- 
- !ruby/struct:VCR::HTTPInteraction 
  request: !ruby/struct:VCR::Request 
    method: :get
    uri: http://example.com:80/foo
    body: 
    headers: 
  response: !ruby/struct:VCR::Response 
    status: !ruby/struct:VCR::ResponseStatus 
      code: 200
      message: OK
    headers: 
      content-type: 
      - text/html;charset=utf-8
      content-length: 
      - "5"
    body: Hello
    http_version: "1.1"

Scenarios

Previously recorded responses are replayed

Given

a file named "replay_recorded_response.rb" with:

require 'vcr_config'

VCR.use_cassette('example', :record => :none) do
  response = Net::HTTP.get_response('example.com', '/foo')
  puts "Response: #{response.body}"
end

When

I run "ruby replay_recorded_response.rb"

Then

it should pass with "Response: Hello"

New requests are prevented

Given

a file named "prevent_new_request.rb" with:

require 'vcr_config'

VCR.use_cassette('example', :record => :none) do
  Net::HTTP.get_response('example.com', '/bar')
end

When

I run "ruby prevent_new_request.rb"

Then

it should fail with "Real HTTP connections are disabled. Unregistered request: GET http://example.com/bar"
