:none

The :none record mode will:

  • Replay previously recorded interactions.
  • Cause an error to be raised 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.configure do |c|
  c.hook_into                :fakeweb
  c.cassette_library_dir     = 'cassettes'
end
And
a previously recorded cassette file "cassettes/example.yml" with:
---
http_interactions:
- request:
    method: get
    uri: http://example.com/foo
    body: ''
    headers: {}
  response:
    status:
      code: 200
      message: OK
    headers:
      Content-Length:
      - '5'
    body: Hello
    http_version: '1.1'
  recorded_at: Tue, 01 Nov 2011 04:58:44 GMT
recorded_with: VCR 2.0.0
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"
  • @exclude-jruby
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 "An HTTP request has been made that VCR does not know how to handle"
