All

The :all record mode will:

• Record new interactions.

• Never replay previously recorded interactions.

  This can be temporarily used to force VCR to re-record a cassette (i.e. to ensure the responses are not out of date) or can be used when you simply want to log all HTTP requests.

Background ()

Given a file named "setup.rb" with:

$server = start_sinatra_app do
  get('/')    { 'Hello' }
  get('/foo') { 'Goodbye' }
end

require 'vcr'

VCR.configure do |c|
  c.hook_into                :webmock
  c.cassette_library_dir     = 'cassettes'
end

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

--- 
http_interactions: 
- request: 
    method: get
    uri: http://localhost/
    body: 
      encoding: UTF-8
      string: ""
    headers: {}
  response: 
    status: 
      code: 200
      message: OK
    headers: 
      Content-Length: 
      - "20"
    body: 
      encoding: UTF-8
      string: old response
    http_version: "1.1"
  recorded_at: Tue, 01 Nov 2011 04:58:44 GMT
recorded_with: VCR 2.0.0

Re-record previously recorded response

Given a file named "re_record.rb" with:

require 'setup'

VCR.use_cassette('example', :record => :all, :match_requests_on => [:method, :host, :path]) do
  response = Net::HTTP.get_response('localhost', '/', $server.port)
  puts "Response: #{response.body}"
end

When I run ruby re_record.rb

Then it should pass with "Response: Hello"

And the file "cassettes/example.yml" should contain "Hello"

But the file "cassettes/example.yml" should not contain "old response".

Record new request

Given a file named "record_new.rb" with:

require 'setup'

VCR.use_cassette('example', :record => :all) do
  response = Net::HTTP.get_response('localhost', '/foo', $server.port)
  puts "Response: #{response.body}"
end

When I run ruby record_new.rb

Then it should pass with "Response: Goodbye"

And the file "cassettes/example.yml" should contain each of these:

| old response | | Goodbye |
