Project: Vcr 3.0.1

Publisher: VCR

:new_episodes

The :new_episodes record mode will:

Record new interactions.
Replay previously recorded interactions.

It is similar to the :once record mode, but will always record new
interactions, even if you have an existing recorded one that is similar
(but not identical, based on the :match_request_on option).

Background

Given

a file named "setup.rb" with:

$server = start_sinatra_app do
  get('/') { 'Hello' }
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://example.com/foo
    body: 
      encoding: UTF-8
      string: ""
    headers: {}
  response: 
    status: 
      code: 200
      message: OK
    headers: 
      Content-Length: 
      - "20"
    body: 
      encoding: UTF-8
      string: example.com response
    http_version: "1.1"

Scenarios

Previously recorded responses are replayed

Given

a file named "replay_recorded_response.rb" with:

require 'setup'

VCR.use_cassette('example', :record => :new_episodes) 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: example.com response"

New requests get recorded

Given

a file named "record_new_requests.rb" with:

require 'setup'

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

When

I run ruby record_new_requests.rb

Then

it should pass with "Response: Hello"

And

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

example.com response

Hello
