Cassette format

VCR Cassettes are YAML files that contain all of the information
about the requests and corresponding responses in a
human-readable/editable format. A cassette contains an array
of HTTP interactions, each of which has the following:

  • request
    • method
    • uri
    • body
    • headers
  • response
    • status
      • code
      • message
    • headers
    • body
    • http version
Scenarios
Request/Response data is saved to disk as YAML
Given
a file named "cassette_format.rb" with: 
require 'vcr_cucumber_helpers'
include_http_adapter_for("http_lib")

start_sinatra_app(:port => 7777) do
  get('/:path') { ARGV[0] + ' ' + params[:path] }
end

require 'vcr'

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

VCR.use_cassette('example', :record => :new_episodes) do
  make_http_request(:get, "http://localhost:7777/foo")
  make_http_request(:get, "http://localhost:7777/bar")
end
When
I run "ruby cassette_format.rb 'Hello'"
Then
the file "cassettes/example.yml" should contain YAML like: 
--- 
- !ruby/struct:VCR::HTTPInteraction 
  request: !ruby/struct:VCR::Request 
    method: :get
    uri: http://localhost:7777/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: 
      - "9"
    body: Hello foo
    http_version: "1.1"
- !ruby/struct:VCR::HTTPInteraction 
  request: !ruby/struct:VCR::Request 
    method: :get
    uri: http://localhost:7777/bar
    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: 
      - "9"
    body: Hello bar
    http_version: "1.1"
